In detail: do-it-yourself repair of the refrigerating chamber from a real master for the site my.housecope.com.
The Italian brand Indesit refrigerators are well-known and loved in Russia. The production is organized in Lipetsk. Good value for money, reliability of the device and availability of spare parts make the products popular. Malfunctions in the Indesit refrigerator occur due to aging, the development of a service life.
Most of the Indesit refrigerators are two-compartment, on their examples we will consider the malfunctions characteristic of these models. Signs of a malfunction of the compressor of the Indesit refrigerator are:
the unit works noisily, with uncharacteristic knocking, whistling;
starts for a few seconds and stops;
does not generate cold.
Replacing a compressor, filling the system with refrigerant is an expensive and complex repair. It is caused by prolonged operation of the device in conditions that do not meet the requirements for operation or the development of a resource.
The most common and less costly reason will be the failure of the thermostat. The manufacturer has set the operating time for the thermostat at 5 years. Symptoms of a malfunctioning thermostat:
The temperature in one of the chambers does not hold.
The compressor may not turn on, it may run continuously.
The electromechanical thermostat does not emit a characteristic click when the knob is turned to 0.
You can replace the temperature sensor yourself. The node is connected to the thermostat.
Why is the cooling mode not maintained in the chambers? If the compressor does not turn on, you need to check the contacts of the start-up relay. They may burn out or stick and need to be replaced.
Long-term operation of the device is accompanied by the gradual volatilization of freon. In case of mechanical damage to the evaporator, leaks during corrosive wear of the joints of the copper and aluminum pipes, in the door heating circuit, the gas quickly leaves the circuit. The lack of freon impairs the performance of the refrigerator. Heat dissipation is reduced. The signs will be a rise in temperature and the formation of a "fur coat" in the refrigerator. It is necessary to refuel the circuit with freon.
Video (click to play).
The refrigerator will work with the same symptoms as a lack of freon if the capillary tube gets clogged. The difference is determined by the temperature of the condenser and its heating zones.
A defective circuit board in an electronically controlled refrigerator will paralyze all systems. Failure occurs when there are power surges in the network. To avoid problems, all devices with electronic control units must be connected through a voltage stabilizer.
For Indesit refrigerators with No Frost, malfunctions are possible associated with the operation of the fan and thawing of ice. The electronic board displays the code F04. The fan may stop due to freezing of the blades, a malfunction in the electrical circuit. To defrost the inner ice behind the wall and in the chamber, to dry it, it is necessary to run the fan for at least a day. Ice builds up on the propeller when the ice defrost heater on the evaporator is not working. It turns on at the command of the thermostat. Possible malfunction of heating element, wiring, thermostat. Error code F7.
Each model of refrigerators has features in design, cooling circuit, electrical and electronic control circuits. Let us analyze the malfunctions characteristic of different Indesit refrigerators, why they do not turn on, do not freeze.
Two-chamber model, with 1 compressor, electromechanical control. Condensate drain from the refrigerating chamber is drip, the freezer requires manual defrosting.The refrigerator is very reliable, during normal operation it has been working without repair for more than 10 years.
A typical breakdown in the model is the failure of the thermostat. This is a housing part with internal relay contacts and a membrane. If the unit malfunctions, the refrigerating chamber does not work, and the temperature in the freezer drops. Due to the inability to analyze, the sensor sends incorrect commands to the module. The compressor can run non-stop and cause damage. The motor will not turn on if the sensor does not give a start command.
The thermostat cannot be repaired and must be replaced. To do this, the refrigerator is disconnected from the network, and the sensor is replaced, according to the instruction manual. We offer you to watch a video on replacing the thermostat on the refrigerator.
VIDEO Two-compartment combined refrigerator with one compressor and electromechanical control. The Nou Frost defrosting system in the freezer and the "crying" wall in the cold chamber are used.
The temperature control in the chambers is independent, thanks to the presence of a magnetic valve on the refrigerant line between the freezer and the refrigerator. Defective components of the Indesit refrigerator of this model, when the temperature in the chambers does not hold, can be:
freezer thermostat, if the desired minus is not typed in the freezer;
thermostat of the upper chamber, if the temperature in the refrigerator is incorrect;
sticking of the switching solenoid valve;
Freon leakage or compressor failure.
Elimination of the causes is possible after a full diagnosis by the specialists of the service center.
In the condensate drainage system, the condensate drainage system in the refrigerator may become clogged. Failure of heaters in the Know system will result in freezer growth in icing. The fan will stop clogged with ice. An inoperative defrost timer will also lead to such consequences.
A specialist can find and eliminate the malfunction, but before that, the lower chamber should be defrosted within 24 hours. During this time, the blades of the refrigerator will be released, and it will be possible to check whether the No Frost power grid is working properly.
The refrigerator is two-compartment, with the lower location of the freezer has an energy efficiency class A. Apparatus with one compressor with full Know Frost in the chambers. On the forums, the model is characterized as reliable, malfunctions happen, but the masters advise you to carefully consider the service.
The model with an external condenser mounted in a grid above the motor will last longer if the heat exchanger is thoroughly cleaned of dust and pet hair once a year.
If the Indesit refrigerator does not freeze, malfunctions may be identified:
damage to the network or lack of power.
malfunctions of the thermostat;
Freon leakage due to the appearance of fistulas in evaporators or refrigerant pipes;
plug in the capillary system.
failure of the motor-compressor.
The Know Frost system in both chambers is located behind the refrigerator wall. The products are cooled by an air stream, condensate is deposited inside the system. The main symptom of a malfunction of the air-cooled Indesit refrigerator is the appearance of ice inside the chamber and an increase in temperature due to a violation of heat transfer.
After a complete defrosting of the chamber with an inoperative fan, it turns out:
the defrost timer has failed;
open circuit in the heater power supply;
the fan has broken.
If puddles form under the refrigerator, you need to check the integrity and serviceability of the condensate drainage system into the container installed on the compressor.
The appearance of frost in the refrigerator when the fan is running indicates a violation of the tightness of the chamber. It is necessary to check the fit of the seal, its integrity. Adjust or eliminate door slack. Choose a more correct operating mode. Optimally, choose a medium setting.
The refrigerator is two-compartment, with the lower location of a small freezer of 63 liters, energy efficiency class B. In the chambers, Nou Frost defrosting is used.
The main reason for the malfunction of the Indesit refrigerator of this model will be the failure of the thermostat, the device that maintains the set temperature in the cabinets. Symptoms of a malfunction are:
the refrigerator does not turn on, but there is a light inside;
the compressor runs continuously;
subzero temperature in the cold chamber;
the compressor has stopped freezing.
How to check the compressor's performance, find the one you need for the freezer and refrigerator, change it yourself, a step-by-step video instruction is offered.
However, the master may find other reasons as well. These include the lack or absence of freon, clogging of the capillary tube by the decomposition products of the refrigerant in reaction with oil, and compressor malfunction.
Refrigerator series Giugiaro with bottom freezer. The device is electronically controlled. Used by Know Frost in both branches. There is a freshness zone. Adjusting camera modes on the front panel at the same time. There is an indication of the parameters of work and a signal in case of deviations or violation of the tightness of the circuit. The energy efficiency of the equipment is class B. The main malfunctions of the Indesit refrigerator of this model relate to the control system and the cooling circuit.
In the refrigerator, the electronic control system can fail in case of voltage surges in the network. Therefore, the device must be connected through a stabilizer. The problematic knot is the complete Know Frost system. Most often it is necessary to change the fan or the power supply to it. If water flows from under the refrigerator, you need to revise the condensate removal system.
Freestanding refrigerator with electromechanical control. Used for manual defrosting of the freezer and drip defrost for the refrigerator. The compact device with a height of 167 cm has a volume of 241 liters.
The main malfunction of the Indesit refrigerator, when the refrigerator does not keep the temperature, the lower cabinet does not freeze. There are several reasons, the main ones are:
malfunction of the thermostat in the upper chamber and the thermostat in the lower one;
absence or lack of freon due to leakage in the circuit or damage to evaporators;
plugs in the capillary system;
failure of the motor-compressor or starting relay.
But first of all, when melting food is found, you need to check whether there is voltage in the power line, whether the power-on indicator on the refrigerator is on.
What kind of refrigerant the refrigerator is charged with is a question that is rarely asked. There are 2 types of refrigerants used in refrigerators for Europe and Asia. Freon R134a replaced the prohibited R12. It is believed to have depleted the ozone layer. With the introduction of the new component, the capillary tubes began to clog more frequently. It is believed that freon reacts with the oil in the system, creates a sediment, clogging the capillary in 5-6 years. Isobutane, the R600a refrigerant brand, is free from these disadvantages. The unit runs quietly, the filling volume is 30% less. However, in the event of a leak, it is more expensive to repair the device. The gas is explosive, the equipment for working with it is more expensive. The refrigerant isobutane is more expensive than freon. For single-compressor double-chamber refrigerators, the R600a filling is more reliable.
An illustrative and detailed lesson by the master on how to choose and install a thermostat on your own, without spending money on calling specialists.

Very often household appliances, which are subjected to daily intensive use, fail. A private foreman for the repair of refrigerators can assign a fairly round amount, but fortunately, all the work can be done with your own hands.
Before starting repair work, you need to find out the place and reason for the strip. The simplest, most accessible, but at the same time, and dangerous indicator is water, which can flow under the freezer or flow out directly from the refrigerator. If a Soviet refrigerator is leaking, then there may be two reasons:
Drainage is clogged;
The container in which the condensate collects is overfilled;
The drain pipe is leaking.
It will not be difficult to eliminate such breakdowns, but we will tell you more about this below. If the water does not flow, and the Electrolux, Nord, Ariston and others simply stopped working, then you need to carry out a comprehensive diagnosis.
Urgent repairs of even the most complex refrigerator can be done at home with your own hands. Let's take a look at step-by-step instructions on how to troubleshoot the most common problems in refrigeration systems.

Refrigerator repair prices depend on the type of problem and the specific company. Sometimes different consumables and urgent call of specialists are also separately taken into account. Consider the price list for replacing the compressor motor:
Some buyers do not even know that the world famous Italian brand Indesit is produced in Russia, in the city of Lipetsk. That is why the products are famous for the excellent ratio of low prices and excellent quality. Throughout the territory of the Russian Federation, sales of refrigerators of this brand are constantly growing due to a rather low percentage of failures, but the appearance of malfunctions in refrigerators of the Indesit brand still happens.
Breakage of this element for any class and brand of refrigerator leads to rise in temperature in the refrigerator chambers, because it is the relay that controls the operation of the compressor, which ensures the normal circulation of freon. A typical cause may be the appearance of carbon deposits on the terminals contacts of the electric motor - you must immediately check the connectors for the presence of moisture, check the correct connection, if an independent repair has already been carried out before.
Due to incorrect connection, a short circuit may occur, the start-up relay will have to be changed due to its burnout. The operation of this device, and how a possible problem is eliminated, can be studied in detail with the help of this video:

The modern unique system "No Frost" (translated from English means "no frost") is becoming more and more popular. It allows the hostess to completely ignore whether there is ice or a snow coat inside the product. The Indesit Know Frost system is installed in every product, but sometimes users may notice areas of frost, which means various breakdowns. Very often, the service center of this model is called with such complaints.
Refrigerator cannot freeze food - the engine is running, but the temperature inside does not drop. The reasons may be as follows: malfunction of the thermostat, refrigerant leakage, violation of the seal on the door.
Product does not function , despite the fact that it is connected to the network or turns on for only a few seconds - a relay failure, a faulty electrical wiring or an electronic unit has failed, you need to call a specialist.
Formed snow coat and its growth increases - check the temperature sensor, the small-section capillary tube is clogged or it has been moved.
Typically, the compressor or temperature sensors fail much more often. Do not load the refrigerator to the top, wipe the shelves and walls of the refrigerator compartment, as soon as the above-described malfunctions occur, immediately call the service center and call the technicians.
It is enough to keep the refrigerator door open for several hours - the frost will disappear naturally, and it is recommended to defrost it once every 7 months.
"Snow coat" in the freezer
Indesit products may themselves report internal problems to the user. For example, fan failures are reported by displaying error code "F04". To eliminate the malfunction, you need to check the circuit between the device itself and the board that controls its proper operation. We measure the resistance or connect the fan directly to the network, if it does not spin, a new one is needed, which can be bought in a specialized store or ordered in an online store with home delivery.
Various malfunctions of this part are indicated by signal "F07" or three LEDs light up at once. It is worth warning users that not all error codes that appear on the display correspond to a real failure of equipment - the command apparatus is just as likely to make mistakes as people. It is best to assume that the error code is just an assumption that the heating element of the defrosting system is faulty, so everything should be checked.
First, we measure the resistance in the circuit, then we find out the state of the fuses, maybe one of them has blown. If everything is normal, it is necessary to change the heating element, it is better to entrust this operation to the master from the service center, because he will check everything thoroughly and diagnose the exact cause.

The entire life of the Indesit refrigerator depends on the correct operation of this unit. Long-term operation can be the cause of compressor failure. The so-called heart of the product can be unstable due to frequent power surges and surges, for which our electrical networks are famous.
The compressor is not repaired, experts say: it must be replaced immediately and seriously think about purchasing a new refrigerator.
If the compressor of your refrigerator constantly drives freon, there is no nominal temperature in the freezer and refrigerating chamber, during operation the unit may emit extraneous sounds, then the visit of the wizard for a complete diagnosis of the product should not be postponed for a long time.
There are malfunctions that are not as easy to detect as it seems: it is necessary to observe the operation of the refrigerator for some time and carefully examine its mechanisms. Signs of a persistent refrigerant leak are the following:
the appearance of frost in the chambers of the product;
there is no sufficiently low temperature in the chambers (users complain that their Indesit refrigerator does not freeze well or does not freeze at all);
a noticeable swelling sometimes forms on the back wall of household appliances;
the compressor runs continuously or intermittently.
Freon leakage occurs more often in two-chamber products with bottom freezer ... Both chambers are connected by a heat pipe, through which freon is distilled throughout the refrigerator. Even a small amount of water vapor can destroy the integrity of this connection due to corrosion - this can subsequently lead to various failures. Freon has neither taste nor smell, so its leakage cannot be determined without special equipment.
It's important to know! Household refrigerators contain too little inert gas to harm the human body.

When you feel a small electrical discharge when in contact with the body of household appliances, then such a product cannot be used. We urgently need to find out the reason for the breakdown to the case, for this there is a simple method: you need to measure the insulation resistance of the device with a megohmmeter ... We turn off the refrigerator and visually inspect all the wires, if it is not possible to visually establish the malfunction, we begin to check the wiring one by one.
We connect the “Earth” wire from the device to the body, and the “Line” wire - alternately touch the wires going to the relay, thermostat, compressor. After finding the wire where there was a breakdown, replace it with a new one. Experienced craftsmen advise - it is better not to risk additional insulation of a faulty wire.
Such odors can appear inside the refrigerator due to the fault of users, when placing products with strong odors, when the freezer is not wiped dry after defrosting. Odor can be removed quite easily.
Remove all food from the refrigerator compartment.
Place a bowl of water and water in this chamber. lemon juice one to one, close the door tightly and unplug the refrigerator to defrost the freezer.
After defrosting, which will last several hours, wipe all the walls of the chambers and shelves with a mixture of lemon juice and water, leave closed for a few minutes, but no more than half an hour.
Wipe the inside of the entire refrigerator with a dry, clean cloth. Lemon vapors and its juice remove not only the smell, but also remove it from the walls and shelves fatty deposits and dirt.
The refrigerator can be used no earlier than 5-10 hours, because it must be well ventilated. This operation is best done in the evening, before going to bed, and by the morning your refrigerator will be as good as new.
Indesit refrigerators can have problems with light: although the bulbs are not very powerful, they tend to burn out at the most inopportune moments. Replacing them is not laborious - we unscrew the bolt that holds the plafond, remove it, and then unscrew the light bulb from the socket. Spare 15 W lamps can be bought at any specialty store. Carefully screw the new miniature light bulb into the socket, install the shade in its original place and fix it.

The article can turn out to be quite large, so I want to say right away that the repair of the Indesit No Frost refrigerator, with a completely electronic control system and a refrigerator that has a thermostat, is practically no different in principle. Before proceeding with DIY repairs, let's take a look at how our brand's No Frost system works. I will now consider two options, about the first I have an article that you can read at this link, despite the fact that the article is about general breakdowns, there is still a lot of useful information, both for a novice master and a repairman with experience. In general, the whole dry freezing system consists in the fact that the fan drives cold air throughout the refrigerator, while the main cold remains in the freezer, and part of it goes into the refrigerator. Thanks to the flap, the temperature in the refrigerator compartment can be adjusted, that is, the flow of cold air into this compartment can be reduced or increased.
Indesit Nou Frost refrigerators, which have an electronic defrost timer and a mechanical defrost sensor, have proven themselves not only for reliability, but also for ease of repair. I will not pull the cat by the tail and will immediately begin to tell you what to do if your refrigerator refused to work normally
No cold in the refrigerator compartment
I note that I am now talking about the complete Know Frost, if you have a refrigerator with a mixed system, then this problem usually arises due to the leakage of freon (refrigerant) on the crying evaporator, which is located behind the plastic on the back wall of the refrigerating chamber, about this you can find out here ... Let's return to our rams and find out why the cold in the upper compartment disappeared. Usually this breakdown is related to ice build-up on the freezer evaporators, so the first thing you need to do is get to the evaporator and see if there is ice on it. If it is completely in the snow, then there is only one conclusion - the defrosting system is not working properly or the spiral of the defrost heating element is in a cliff. Now you can list the actions that you must take in order.
You will be surprised, but this completes the elimination of this malfunction, that is, in this case, you need to stupidly change the defrost sensor and the electronic timer. Just do not save, it will come out sideways, of course, if you are repairing your refrigerator, then you can first replace the timer, and then the sensor. It's just that these details are very difficult to check, and as I wrote above, it seems that a working part may malfunction on the unit itself
No frost in the freezer
In this case, everything is much worse and more complicated, if you are faced with this problem, then it is better to contact a qualified technician, because the problem may be associated not only with ice freezing, but also with the failure of the thermostat, engine start relay, compressor, and it also happens freon leak.Now let's see what signs indicate a malfunction of a particular part.
We have more or less figured out all the main malfunctions of the refrigerator, which has a defrost timer, now you can proceed to the second step, namely, answer the frequently asked questions that sound on my YouTube channel
I have an Indesit No Frost refrigerator, which is about 10 years old. In general, the upper chamber refused to work, where the main products are, the freezer is also slowly dying. We were advised to turn off the refrigerator for a few days, we turned it off and both cameras started working fine. After about 2 weeks, the situation repeated itself, that is, the refrigerating chamber began to work poorly, or rather, the cold disappeared altogether, and then the freezer also began to freeze worse. I watched your YouTube video, checked the defrost sensor and the heating element, they turned out to be working, so I came to the conclusion that the timer is faulty. Of course, I replaced it, but the malfunction has not disappeared anywhere. What do I need to do next
In this article, I mentioned that if the refrigerator compartment does not work, and the freezer compartment is functioning normally, then you need to change two parts - a sensor and a timer, you do not need to be greedy. It is these details that are responsible for the correct operation of the heating element, that is, you also need to change the defrost sensor
Hello, the fan in my refrigerator has stopped blowing, and the light has also gone out, that is, the light is not on, behind the back wall in the freezer, you can hear the sounds of a seething sea. It is clear that the refrigerator does not turn off and the cold in both compartments disappeared. I checked the fan, just connected 220 volts to it, it blows fine, but it does not turn on on the refrigerator
Very often, such a breakdown is associated with a button that turns off the light, it is double, that is, it turns off the light and turns on the fan. First of all, you need to change it. This is done specifically so that the refrigerator does not collect excessive condensation, that is, when the door is opened, the fan should turn off
My Indesite No Frost refrigerator does not freeze. The fact is that the upper chamber, that is, the refrigerator compartment, is working normally. In general, I measured the temperature, it turned out to be + 5, and in the freezer somewhere around 0. Tell me what needs to be tweaked or replaced so that the freezer has a normal temperature
You don't need to twist and change anything, you need to call a specialist. Such a problem is associated with a freon leak, that is, it is necessary to find the leak, eliminate it and refuel the system. The capillary can also be clogged, but even in this case you cannot cope without a master, because you need to fill the refrigerator with freon
Tell me why the compressor starts up for a few seconds, I changed the relay, but it's no use. Anyway, after plugging in the refrigerator, it works for about 30/40 seconds maximum
Many people think that if the relay is replaced, the motor-compressor will start working. In the vast majority of cases, this will not happen. To avoid wasting money, remove the starter relay and take it to a workshop. A normal master will immediately determine what burned out - a motor or a relay
If you know how to hold a screwdriver and pliers in your hands, then I think it will be possible. The power of the heating element, in almost all refrigerators is the same, you need to pay attention not to the power, but to the configuration, that is, so that the heating element has the same bends as the native
There are only 2 or 3 types of heaters on the Indesites. Remove this part from your refrigerator and just compare it with the photo of the item you want to buy, at the same time you will find out the price of this part.
Watch video how to repair Indesit No Frost refrigerator with electronic control module
VIDEO
If you haven't watched the video above, then I advise you to watch it, it tells about many of the nuances of repairing the Indesit No Frost refrigerator with an electronic control module.When starting to repair such units with your own hands, you first need to find out the resistance of the freezer evaporator sensor (defrost sensor) and the resistance of the freezer temperature sensor
Defrost sensor resistance for refrigerator Indesit → about 14 kΩ at room temperatureResistance of the sensor sensor of the freezer compartment of the Indesit Nou Frost refrigerator → the same 14 kOhm at + 20 0 СIf your refrigerator has lost the cold in the refrigerator compartment, then first of all you need to look at the ice freezing on the freezer evaporators, if there is one, you need to check the evaporator sensor and see how it changes resistance when exposed to heat or cold. In the video I shot, I focused on the thermal fuse. In this model, two thermal fuses were installed in the body of one part, if one of them fails, then the defrost will not turn on. They are checked by ringing, that is, for an open circuit. In principle, the repair of new refrigerators is practically no different from the repair of old ones, that is, where there was a defrost timer and a thermostat. Of course, there is a big difference in the component parts, but the principle is the same and if you understand it, then it will not be difficult for you to cope with the malfunction. I have selected several comments that sounded on my YouTube channel, I think my answers to these questions will in many ways clarify the breakdowns that are associated with the failure of the electronic part of this refrigerator.
The cold in the refrigerator compartment disappeared when I got to the freezer evaporator and saw that it was covered with frost. I’ll even say more, half of it was in the ice, and the rest was kind of wet and covered in snow. I measured the defrost sensor, its resistance was 18 kOhm. I pulled it out of the freezer evaporator and measured it again, it turned out to be about 12 kOhm. I checked the heating element, the resistance on it is 380 Ohm, I also checked the sensor for ringing - two blue wires are ringing among themselves and two yellow wires are ringing too. What is the problem, I don't understand, everything seems to be working fine
It is quite possible that the problem is in the freezer evaporator sensor, it is advisable to change it. The fact is that the defrost is not working properly, and since you checked the heating element and thermal fuses, and they turned out to be intact, then there is only one part that needs to be replaced - this is the defrost sensor. Although, according to your data, its resistance seems to be normal, this spare part may be buggy when the refrigerator is running. There is another option, but it is unlikely - this is a control module. It happens that the relay on the unit sinks and the defrost does not turn on, but this happens very rarely. First, change the sensor
As I understand from the video, you changed two fuses for the sensor, which contains a thermostat and a thermal fuse. I know a little about electromechanics and I understand that the system seems to have remained the same and the principle is the same, but still I would like to know, so there was no repetition of the refrigerator. Excuse me for my skepticism, but I, as a master, must be confident in the performance of this system.
More than two months have passed, and during these two months there was a major heat, changed in early June, now the end of August. In general, the season worked without problems, so I conclude that the system is efficient. The fact is that at that time I did not have such sensors and there were no such sensors on sale either, so I had to do know-how.
The light in the refrigerator went out, the light bulb is working, and to hell with it with a stop light bulb, you can live and use it without light, but as I understand it, the fan does not work, I checked it, in short, I connected 220 volts to it and it blows like crazy. In general, the refrigerator stopped turning off, the temperature disappeared, the master came and said that there was a leak. I'm not a craftsman, but I guessed to touch the condenser on the back of the refrigerator, it was hot.I watched your videos and saw how you conduct a magnet in the area where the control unit is located, I did the same, but there was no reaction. Thank you for seeing how you showed how the module is removed, as a result, I discovered a problem in the glass piece that stands on the block. Inside this part, you can see 2 contacts, which, it seems to me, should be closed or open when the magnet approaches. This does not happen for me, I checked it with a tester. Tell me, do I correctly think that this particular part is responsible for the light and the fan or something else.
Yes, this is a kind of switch, when the magnet is acting on this part, the contact must close or open. Try to change it, it is quite possible that the glitch comes from it, poor-quality soldering of parts is also found, check if this part is well soldered to the board. On the control unit, you will find a triac that controls the fan, if it does not help, you can also change it
That's all I think if you haven't found any answers to your questions, then you can safely ask them on my youtube channel. The only thing I want to add is that in this paragraph, I just supplemented what was said above. You must understand that most of the failures of the Know Frost system are associated with the electromechanical part. You only need to check 4 parts: defrost sensor, freezer sensor, thermal fuse and heating element. If everything is in order and there is ice on the freezer evaporators and you do not know what to do, then my advice to you, it is better to call the master and let him rack his brains
You can tell a lot about the repair of Indesit refrigerators and 1 article is clearly not enough for this, since this brand produces not only a large number of models, but also refrigerators with different defrosting or freezing systems (here whoever wants it is called). I will try to succinctly tell you about each of these systems, but still I will pay more attention to the crying defrosting system, since today, these are perhaps the most common refrigeration units in the homes of residents of the former Soviet Union, I will pay special attention to automation, because it is the malfunctions associated with a thermostat or relay, you can do it yourself, as for a freon leak or a motor replacement, in such cases you cannot do without the help of a master. There is also an important point related to the engine, that is, the compressor, the main thing here is to correctly diagnose its breakdown. It often happens that at first glance the motor is out of order, but as a result it turns out that this part is quite working. Now, after you have done a small introductory part, you can start looking for the causes of the malfunction of your refrigerator.
In more than 50%, the thermostat or relay fails, but the real scourge for these refrigerators is the leakage of freon in the foamed part of the case, below I will try to list all the malfunctions that are associated with this defrosting system. Here I would immediately like to note that if the master has identified a freon leak in your refrigerator and recommends that you install a crying evaporator on the back wall in the refrigerator compartment, then it is advisable to agree with this, do not be greedy. This is so, a small digression, but on the case, and now I will list everything that can break in your coldness
Motor start relay - In this case, the motor simply does not start or starts for a few secondsFridge motor burned out - The signs are the same as in the first paragraph, plus if you hear a barely noticeable hum of the engine, then most likely a kirdyk came to him, read the rest belowFreon leak - No cold in the refrigerator compartment or frost in the freezerCapillary clogged - The same as in the previous case, that is, in paragraph 3Broken thermostat - The refrigerator does not turn on or works in the wrong modeThen we will disassemble everything in order and first of all, we will start with the most important thing, that is, with the start-up relay and the refrigerator compressor
VIDEO
Now let's add a little more, this paragraph. It happens that the engine runs for an hour or 2, but after it is turned off by the thermostat, the compressor cannot start, this is more due to the overheating of the motor and therefore, until it cools down, it will not work. There is only one reason, it sticks the piston on the compressor and fix it, such a malfunction, you can only change the engine. In general, if the refrigerator engine does not start, then first of all, remove the relay and take it to the workshop, a master, who thinks a little, will immediately determine the breakdown. It is very important, do not poke every 5 seconds, plug into the outlet, this cannot be done, the minimum interval between turning off and on must be at least 10 minutes
Here it is, the biggest mess, in two-compartment refrigerators with a drip thawing system. As you guessed, we will talk about a freon leak and a clogged capillary. If the injection tube, that is, the capillary, is clogged, then first of all you need to look at the heat exchanger, this is a metal grill on the back of the refrigerator, it is also called a condenser or a radiator. In general, it is advisable to check how this heat exchanger heats up, if two rolls are very hot to the touch, and the rest are cold, then most likely we are talking about a clogged filter or capillary tube. Without a master, you cannot make such repairs with your own hands. For complete reliability of the picture, it is necessary to release the gas from the system, drop the air pressure into it and see the passage of the capillary tube at the outlet. If, at the exit from the capillary, the air blows well, that is, as expected, then it is necessary to insert a crying evaporator. An illustrative example of such work, I showed in the video, which you can watch below, and now let's look at the signs that a freon leak has occurred in the refrigerator
The temperature in the refrigerator compartment has risen
On the back wall of the refrigerator compartment, there is a swelling of plastic, that is, the so-called flapper, you can easily determine this by pressing on the plastic, if there is a free space under it, then a crying evaporator must be installed 100%
The temperature in the freezer is too low and the temperature is too low to shut off in the refrigerator
Unpleasant smell of oil is felt
The refrigerator does not turn off
In the corner on the back wall of the refrigerator compartment, there is ice, that is, a block of ice

Above, I have listed how to determine the malfunction if your refrigerator is leaking. Here it is necessary to add the following, freon has no smell, it smells like oil and therefore it is practically impossible to smell the leak. Now, we will talk about how the masters calculate the leak in visible places. First of all, you need to touch the radiator tubes near the engine, if there are oily places, then it is likely that the freon came out exactly where you found this muck. You also need to pay attention to the intermediate bar between the refrigerator and freezer, if it is very rusty and smells of oil, then it is quite possible that the leak occurred right here, it happens in 10% out of 100. The fact is that behind this bar there is a defrost circuit, it is a metal tube through which the refrigerant circulates, it heats up the iron bar, look at the photo below, this is done in order to remove condensation from under the rubber band
The first step is to properly check the thermostat. On Indesit refrigerators with a crying defrosting system, there is a "super freeze" function, this is such a button, when pressed, your refrigerator can work for weeks without shutting down, with its help - the motor is connected directly without a thermostat.To begin with, if there is such a button, try clicking on it, see the photo below, if this button is not there, then we will do the following procedure
We need to get to the thermostat, remove the top cover, of course, if the thermostat is at the top, you will see the spare part we need under it. The next step, you need to bridge 2 or 3 wires between each other, I draw your attention to the fact that the green wire with a yellow stripe or vice versa is a yellow wire with a green stripe, this is a ground wire that fits to the thermostat body, be sure to remove it to the side, but the other two or three wires, you just need to connect together. Before carrying out this procedure, you must de-energize your refrigerator, that is, unplug it from the outlet. I made a video about this in detail, which you can watch below. Now let's look at the signs by which we can say that the thermostat is out of order.

Now let's see what thermostats are used in Indesit two-compartment refrigerators.
C 59 - Suitable for almost any model of Indesit two-compartment refrigerators. You do not need to look at the modifications of this thermostat, it is important for you that the length of the thermostat tube is sufficient, and otherwise they do not have any differencesThere 133 - almost the same as the K-59, it will also fit any model of a two-chamber refrigerator, the main thing is that the length of the thermostat tube is enough, here you have to look at the modification. The fact is that these thermostats are available in different lengths, from 50 cm to 2.5 m.There 145 - Usually stands on Indesit Nou Frost two-compartment refrigeratorsOn this, I consider the topic of thermostats closed, of course there are still nuances associated with this part, but it is simply impossible to describe everything in one article, I think I will soon post material dedicated to this particular malfunction
Too much space was taken up by the story about the crying system, so I will have to write about Nou Frost in Indesit in another article, but now I will try in kration to tell you about the most common malfunctions of these units. The repair of such refrigerators is quite simple, it consists in replacing the automation, and not individually, but as a whole. When such cold weather began to be produced, I, as a little experienced master in this matter, first changed the sensors and then the timers, but as a result I came to the conclusion that this is all garbage. In short, after a while, I got repeats with the same breakdowns. In general, guys, don't be weird, and if your No Frost started to mope, then change all the automation in bulk, don't be greedy. Be sure to watch the video about this.

Here it must be added that the leakage of freon in these refrigeration units is very rare, during my practice I had to eliminate such muck, only a few times. Believe me, I repaired them, more than one hundred, and practically everywhere I changed the timer and defrost sensor, less often I replaced the defrost heating element, it changes just like in refrigerators Samsung, Lg and other brands. Of course, if the breakdown is associated with a leakage or replacement of a heating element, then it is better to contact a good specialist, since this procedure is not easy and here you can find it on the s **** of adventures, but as for the timer and defrost sensor, then this is quite you can do it yourself
Watch a video on how to replace a defrost element in a refrigerator Indesit, Samsung, etc.

In the photo below, the defrost timer controls the defrosting process for the freezer evaporator. Usually, the interval between turning on the defrost heater is from 8 to 12 hours, it depends on how long the refrigerator engine has worked, that is, the total operating time of the compressor is taken into account. By the way, a substitute for this timer may be a clock mechanism from Ariston or Stinol, here it should be noted that these are practically the same refrigerators.It is very difficult to check the defrost timer, for this you need to create a whole structure with a bell, that is, we do the following thing. It is necessary to connect to the circuit, something like an alarm, that is, to make sure that when the clockwork goes into defrost, it would signal us loudly about it
In photo 2, the defrost sensor is a very capricious part, it is difficult to check it. The fact is that it is made on the principle of a thermostat, that is, when the temperature drops, the contacts inside this sensor close and it would seem that you take a multimeter in your hands and just ring it. Yes, indeed, if you remove it from the system and check it in a similar way, then I assure you in 90% of cases it will work like a clock, but as soon as you put it in place, miracles associated with turning it on and off will begin. In general, if this sensor, when checked, showed that it is working, you should not believe it
Freezing ice on the freezer evaporator
There is no cold in the refrigerator compartment
The back grill of the refrigerator is completely hot, but there is no frost. We are talking about a condenser that sits on the back of the refrigerator.

Basically, these are the main breakdowns that we examined in this refrigeration unit. Here it should be noted the following, as in any refrigerator with the No Frost system, first of all you need to get to the freezer evaporator and see the ice freezing, if there is no ice on the freezer, then this already indicates that, most likely, there was a leak or clogged capillary. Above I wrote that in refrigerators with this system, a thermostat is used there 145. Our manufacturer did not become clever and did the most sensible thing, the guys put here something that can be easily replaced and checked. In general, checking this thermostat is no different from checking a thermostat with a crying cooling system. In short, you need to bridge the contacts and listen to the refrigerator engine, if the engine starts up, then the thermostat needs to be changed
