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.

Video: how to repair a refrigerator with your own hands

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:

It is necessary to determine the reasons for the breakdown of the refrigerator. How to diagnose yourself. You will find all this on our website. Error codes and how to fix the breakdown.

New models of refrigerators of various brands appear on the market of household appliances every year. Modern design, applied engineering and technical solutions allow refrigerators to work for a long period without breakdowns. However, as everyone knows, there is no eternal technique. Sooner or later, but consumers have to deal with the renovation of their food keeper.

The first thing that comes to mind to domestic consumers is try to repair refrigerators with your own hands. This makes a certain sense, since indeed some problems can be easily eliminated by yourself with minimal financial costs. To carry out minor repairs, knowledge of the general design of the refrigerator, small skills in working with a measuring tester and knowledge of an electrician are enough. Replacing the seal yourself.

If your refrigerator is not working, it should be checked whether the supply is supplied to it. voltage... To do this, simply open the refrigerator compartment door. If a light appears in the refrigerator and there is a light indication on the information boards, then the voltage is supplied to the refrigerator.

Next, you should check the work thermostat. To do this, set the level to maximum cold using the temperature regulator.If at the same time the operation of the refrigerator does not resume, then the malfunction should be looked for both in the thermostat itself and in the compressor engine or in the circuit for starting and protecting it. As a rule, repairing a relay thermostat, or rather replacing it, is quite simple to perform. It is enough to buy a new one and install it instead of the faulty one.

Work thermostat made on the basis of an electronic sensor, you are unlikely to be able to perform on your own. The relay-based compressor starting system is also easy to check with a conventional tester. If necessary, replacing a faulty one takes no more than ten minutes if a new one is available. It is not difficult to restore the operation of the refrigerator when breakage of visible electrical conductors or oxidation of various contacts on the relay... Malfunctions in this case are eliminated by ordinary stripping and joining. Bad smells in the refrigerator can be eliminated by thoroughly cleaning the refrigerator compartments and by cleaning the clogged drain pipes so that condensation can drain freely. How to defrost the refrigerator correctly.

Modern refrigerators are complex devices built on the basis of microprocessor-controlled electronic blocks that process information from various sensors and sensors, and also control the operation of all systems. In case of failure of electronic control units do it yourself refrigerator repair you can not. Naturally, you will not be able to eliminate compressor malfunctions, violations of the tightness of the refrigerant pipes. Entrust the performance of all specified work to better qualified specialists. Only they can restore the normal operation of all systems. This is especially true for refrigerators with the Nofrost system with complex systems of sensors, heaters and cold air circulation. Do not repair the refrigerator yourself. Trust it only to professionals, who will perform all operations efficiently and will certainly provide you with a guarantee.

The refrigerator most often breaks down at the most inopportune moment. What was the reason, how serious the breakdown is, how it can be fixed - the summary table of refrigerator malfunctions will help answer these questions.

Classic refrigerator (without No Frost system) works as follows:

Now that we are familiar with the refrigerator device, we propose the following sequence of actions:

Try to identify the problem. in the vast majority of cases, this is not difficult by following the instructions for troubleshooting.

If possible, repair it yourself. A person familiar with the refrigerator design and possessing a minimum set of tools is able to eliminate most of the malfunctions not related to the depressurization of the system.

If self-repair is not possible, choose a company, determine the cost of repairs and call a master.

At the end of the repair, adhere to the recommendations for operating the refrigerator.

The sequence of actions to identify the failed part and recommendations for repair. For compressor refrigerators without No Frost system.

Check the voltage in the outlet, it should be in the range of 200-240 Volts, if this is not the case, the refrigerator is not obliged to work (although it may work for a while, especially the old models.)

All repair work must be carried out with the refrigerator unplugged and defrosted!

a) Check if the light inside the refrigerator is on, if it used to be on, but now it is off - there is a malfunction in the power cord or electrical plug (this is a fairly common malfunction and it is not necessary to call a refrigerator repair technician to fix it).

b) If the light comes on, the first thing to do is to check the thermostat:

- we find two wires suitable for the thermostat, remove them from the terminals and connect them together. If
the refrigerator will then work - we change the thermostat and the repair is completed.

c) If the thermostat is working properly. In the same way, we check the button for defrosting the refrigerator.

d) For further diagnostics, you will need an ohmmeter. We disconnect and call the starting and protective relay (they can be assembled in one case), if we find an open circuit, we replace the defective part.

e) The electric motor of the motor-compressor remains, it is difficult to replace it without the participation of a specialist, but since we got to it, it is worth finding out what exactly the malfunction is. There may be three defects in this unit:

- winding breakage;
- turn-to-turn closure of the winding;
- short circuit to the motor compressor case;

How to identify them is generally clear: all three contacts of the electric motor should ring among themselves and not ring with the case. If the resistance between any two contacts is less than 20 ohms, this may indicate an interturn closure.

f) If you carefully completed the previous points and did not find a malfunction, this most likely indicates oxidation of the contacts in one of the connections of the refrigerator electrical circuit. Carefully inspect and clean all the contact groups that you disassembled, restore the refrigerator circuit in the reverse order - the refrigerator should work.

1 - electric motor
motor-compressor
1.1 - working winding
1.2 - starting winding

3 - thermostat contacts

10 - defrost button

11 - protection relay
11.1 - bimetallic plate
11.2 - relay contacts

12 - starting relay
12.1 - relay coil
12.2 - relay contacts

a) Defect in the bimetallic plate 11.1 of the protective relay: determine the malfunction and replace the part.
b) Defective coil (or other current sensor) 12.1 starting relay: determine the malfunction and replace the part.
c) Breakage of the starting winding of the electric motor 1.2: we determine the malfunction and call the repairman of refrigerators to replace the motor-compressor.

a) Freon leakage: Determined as follows - if the compressor is running and the amount of freon is normal, the condenser should heat up, touch it with your hand (carefully, it can heat up to 70 degrees), if after prolonged engine operation it remains cold, then the system is depressurizing ... Disconnect the refrigerator from the network and call the wizard.
b) Violation of the thermostat regulation. The device can be temporarily replaced with a known good one, if the refrigerator works in normal mode - return the faulty thermostat for adjustment.
c) Decreased performance of the motor-compressor. This is a hard-to-diagnose malfunction, call the wizard

a) Violation of the thermostat regulation. The device can be temporarily replaced with a known good one, if the refrigerator works in normal mode - return the faulty thermostat for adjustment.
b) The rubber of the refrigerator door seal has lost its shape and elasticity. If the door does not close tightly, warm air will enter the refrigerator, the temperature regime will not be maintained and the motor-compressor will work with increased load. Carefully inspect the seal, defective - replace. (see also next point)
c) The door of the refrigerator led. The door geometry is adjusted by changing the tension of the two diagonal rods located under the door panel. For more information on how to adjust the door, see Removing gaps in refrigerator doors.
d) Decreased performance of the motor-compressor. This is a hard-to-diagnose malfunction, call the wizard

a) If the refrigerator turns off from time to time, but the temperature in it is too low - slightly turn the thermostat knob counterclockwise, if this does not help - see Violation of the thermostat adjustment
b) The fast freezing button is forgotten in the pressed position - turn it off.

Many malfunctions that subsequently lead to costly repairs to the refrigerator arise as a result of improper operation of the unit. Here are some simple tips:
a) If the refrigerator has been turned off for any reason, wait five minutes before turning it on again. This process can be automated, see the timer to delay the inclusion of the refrigerator

b) If the refrigerator has been defrosted, do not load it with food until it runs empty for one cycle and turns off.

c) Do not set the thermostat pointer further than the middle of the scale, this will not give a significant gain in temperature, and the engine will work in a tense mode.

d) On some refrigerators, a “crying evaporator” is located in the depths of the refrigerating chamber (on the back wall). Do not lean food against it and remember to clean the water drain underneath.

e) When defrosting the refrigerator, it is unacceptable to pick off the ice using hard objects, defrost it only with warm water.

f) On some refrigerators there is a “quick freeze” button (usually yellow) this button closes the thermostat contacts and the engine runs without shutting down. Do not forget this button is pressed.

g) Do not store vegetable oil in the refrigerator, oil is not required, and the rubber of the refrigerator door seal loses its elasticity.

h) Do not place the refrigerator near heating appliances.

The reason for the appearance of water in the refrigerating chamber is defrosting, as a result of improper operation or loss of tightness. Even a small puddle is a bad sign. The refrigerator has time to thaw and flow - look for leaks, as a rule, the sealing rubber does not fit tightly in the door. However, the reason may be trivial, the refrigerator doors were not closed tightly.

Sounds complicated? If you know how to hold a screwdriver in your hands and are more or less versed in technology, this task is within your reach. Let's try together?

The refrigerator belongs to the category of very reliable household appliances. Unlike, for example, washing machines stuffed with electronics in recent years, there is nothing to break in the fridge. A serious problem is the depressurization of the system and the breakdown of the compressor, everything else can be fixed by yourself. So repairing refrigerators is a good warm-up for a guy with hands 🙂

But let's start in order. The first thing to do is try to determine the cause of the breakdown, so to speak, diagnose your refrigerator. Depending on its severity or, conversely, lightness, and should act. Indeed, in some cases, even a blonde can handle the repair of a "broken" refrigerator.

For example, the light inside the refrigerator is off. Before calling the technician, listen to the refrigerator humming. At the same time, keep in mind that he does not do this all the time, but only from time to time. If the refrigerator hums, but the light is off, then, as you might guess, the light bulb has burned out. Unscrew it and go to the store to buy a similar one, and then screw in a new one.

But this, of course, is the simplest case - for blondes. People with higher living habits are able to diagnose faults in the power cord, plug, and electrical outlet. In houses with old electrical wiring, such breakdowns are not uncommon. In this case, of course, you need to repair the electrical wiring, and not the equipment that is powered by it.

If the light in the refrigerator is on, but the refrigerator is clearly not working (not humming, defrosting), the first step is to check the thermostat. In inexpensive models of refrigerators, there are the same inexpensive temperature regulators, the shelf life of which is 5-7 years, which means that after this time they will almost certainly fail. At the same time, replacing the thermostat is not tricky and you can do it yourself. The only question is where to buy a new one - they are not sold in supermarkets.Type in Yandex the query "thermostats for refrigerators ..." indicating the brand of your refrigerator and you get a list of companies from which you can buy this piece, and often with delivery - everything is cheaper than calling a specialist or taking a refrigerator to a service.

The thermostat is used to control the motor-compressor in the mechanical control circuit of the refrigerator and is installed either on the front panel of the refrigerator or in its chamber. We find two wires suitable for the thermostat, remove them from the terminals and connect them together. If the refrigerator works after that, we change the thermostat and the repair is completed.

There is also such a problem with the thermostat: the refrigerator works, but it freezes slightly (it does not freeze at all - another, more on that below). To eliminate this problem, the thermostat must be adjusted or completely replaced. True, the refrigerator can freeze slightly in two more cases: a loose door fit and a decrease in compressor performance. In both of these cases, you cannot do without a specialized service.

Moving further from simple to complex - compressor problems. It is hardly worth replacing it yourself, but you can try to diagnose the malfunction. Truth and your skills in working with equipment should already be an order of magnitude higher than in previous cases.

There can be three defects in a compressor: a winding break, an inter-turn winding short circuit and a short to the compressor case. How to identify them: all three contacts of the electric motor should ring among themselves and not ring with the body. If the resistance between any two contacts is less than 20 ohms, this may indicate a turn-to-turn closure. Alas, we call the wizard and change the unit.

Another possible problem: oxidation of contacts in one of the connections of the refrigerator electrical circuit. Carefully inspect and clean all the contacts, restore the refrigerator circuit in the reverse order - the refrigerator can and should even work.

Well, now one of the most common problems, which you will definitely not be able to solve yourself - the refrigerator works, but does not freeze at all. This speaks only of one thing - the depressurization of the refrigerator system and the leakage of freon - gas, with the help of the evaporation of which all refrigeration systems work. We are taking the refrigerator to the service - you have no other choice. However, there is - buy a new one 🙂

And finally, here are some tips to avoid some problems with your refrigerator (as they say, prevention is better than cure):

1. Do not put the refrigerator regulator in the extreme (coldest) position. The temperature in the refrigerator from this will only be very slightly lower than if you put it in the middle position, but the compressor will work at its limit, which means that it will fail much faster. And electricity will "eat" much more actively.

2. Compressors of all refrigerators, without exception, do not like power surges and often fail because of this. If you live in an area where power surges are not uncommon, use a voltage transformer or an uninterruptible power supply to operate the refrigerator - as a result, it will be cheaper.

3. When defrosting the refrigerator, do not pick off the ice with a knife or other sharp objects (and you do this, right? 🙂 - it's so easy to damage the tightness of the refrigerator system and disable it. - goodbye freon!

4. Do not install the refrigerator closer than one meter from radiators and stoves. Thus, you will again increase the load on the refrigerator compressor (it will have to work in an increased mode to compensate for the heating of the refrigerator from the outside).

5. Do not store vegetable oil in the refrigerator! The refrigerator is not required for oil, but its vapors lose the elasticity of the rubber gaskets, thereby violating the tightness of the door.Of course, in a year or two you will hardly notice it, but in five years you can "reap the fruits" of your hindsight.

And the last thing: perform all diagnostic and repair actions only by turning off the refrigerator from the network. Otherwise it will electrocute you, and I will be to blame for not warning you about this! 🙂

If you understand that repairing a refrigerator is too complicated and expensive, it is easier to buy a new one. How to do this correctly is described in our article - How to choose a refrigerator.

Good luck and longevity to your refrigerator!

Practical advice, nothing more can be done by a layman at home

Please keep in mind that any links, html tags or scripts will be displayed as plain text - it makes no sense to use them. Comments containing obscene language, insults, flooding and advertising will be removed immediately.

Did this advice help you? You can help the project by donating any amount you like for its development. For example, 20 rubles. Or more 🙂

Despite the fact that modern refrigerators are quite reliable and capable of serving for several decades, they also periodically fail. It is worth solving problems with household appliances right away. Some problems can be dealt with on their own, while others require specialist intervention.

Typical problems that you can deal with on your own include:

the appearance of extraneous sounds and rattling;
insufficient or strong cooling of food;
accumulation of water at the bottom of the unit;
not working condition of a light bulb or indicator;

But the serious problems that require the intervention of professionals include:

current piercing through the casing;
turning off the device immediately after turning it on;
the formation of a snow cap on the back wall;
stopping the operation of the motor - compressor;
lack of cooling.

Most often, no matter how trite it may seem, the rattling of the unit is caused by an incorrectly adjusted suspension of the compressor casing. To solve the problem, it is enough to lower the suspension bolts with springs to the required level.

Also, equipment rattling can be caused by contact of the product body with pipelines. This is solved by detecting problem areas and moving the tubes. Relays can also cause jitter. To fix the problem, it is worth making sure that it is located correctly and according to the special labels.

If the refrigeration equipment begins to freeze strongly or weakly, you will need to check several indicators at once:

Sometimes consumers are faced with the problem that refrigeration equipment is electrocuted. This can happen both during his work and in a calm state.

Attention: using a device that shocks is dangerous to life. Unplug it immediately and either fix the problem yourself or call the wizard.

To fix the problem yourself, you will need a special device - a megohmmeter, with which the insulation resistance of the refrigerator wiring is measured. The workflow will look like this:

Disconnect the unit from the mains and check the wires for visible defects.
If you haven't noticed any flaws on the wires, you will need one more device - "Ground". Its wire is connected to the body of the refrigerator, and the second wire - "Line", to the wire of the refrigerator. The “Line” wire is alternately connected to the thermostat, relay and compressor wires, and excessive resistance will be displayed on the screen.
After the location of the malfunction is calculated, the damaged wire will need to be replaced with a new one or carefully insulated.

The refrigerator can start to work continuously if the room temperature rises constantly or the thermostat knob is incorrectly set. Under these conditions, the equipment will operate at full capacity. If the thermostat is set correctly, and the unit operates at full power without interruption, it means that it simply failed and must be replaced. Also, a problem in the constant operation of the compressor motor may be a refrigerant leak. This can only be determined using a special device. It is impossible to repair the equipment on your own without the skill and necessary consumables. It is worth contacting the workshop here.

The thermal relay is often triggered for various reasons:

increased voltage in the electric motor circuit;
the relay is loose;
relay contacts oxidized;
there are faults in the starting relay;
the compressor is seized.

Important: most often the thermal relay often trips due to an increased voltage in the motor circuit. If the problem is not eliminated in time, its winding will burn out.

You can try to fix the breakdown by checking the voltage in the electric motor network. If stable, check the relay. For this, the motor is connected directly without a relay.If, after the performed manipulations, the equipment starts to work properly, you will need to replace the relay.

Sometimes in two-compartment refrigerators, excess moisture appears on the walls in the form of drops of water or a snow coat. This can happen due to long open doors, or if the seal has lost its elasticity. It can also be provoked by the fact that hot food is placed in the unit. Correcting this situation begins with checking all the settings in the cooling system.

Quite often, in modern models, a fur coat on the walls appears when the internal lighting is turned off. It is impossible to see if the backlight is on after the door is closed. To check if the light is on or not, place a thin object between the equipment wall and the seal and close the door. Through the resulting gap, you can determine whether the light is on or not. If it does not light up, then repair the lighting system or replace the button - the switch that comes out of the wall towards the door.

If, after connecting the unit to the network, it does not make any sounds, then the refrigerator does not work completely. This is most often due to the lack of current in the power supply network or to the failure of the refrigerator cord. If there is current, simply replace the cord or plug.

If the refrigeration equipment works, but with a short cycle, this can provoke:

high pressure;
the presence of air in the system;
excess freon;
relay actuation;
dirty fan;
failure of the fan.

For troubleshooting, you need to check if the fan is connected correctly. If there is a small amount of air in the system or there is an excess of freon, they will need to be vented through the valve. Remember to check the condenser for dust contamination. Frequent activation of the low pressure switch leads to clogging of the filter or damage to the expansion valve. In this case, you just need to clean the filter or replace it with a new one, check the relay settings.

Moisture can collect on the bottom of the refrigerator due to the tube misalignment or clogging. You can cope with a breakdown quite quickly if you clean the pipe that leads water to a special receiver using a long and flexible wire. The wire is inserted into the tube and moves along the hole to the bottom of the unit. After a few minutes of the working process, all the debris will go into the water receiver.

Caution: To completely clean the tube, it is best to douche it several times.

An unpleasant smell appears in the refrigerator from improper use. To do this, it is not recommended to place products with a pungent smell in it without special containers, wipe the walls of the device in time and monitor its cleanliness.

If, however, an unpleasant odor still appears in the device, you must quickly get rid of it. Since this will have a bad effect on all the products that are stored in it. This process can take several hours of your free time:

Disconnect the unit from the network and leave it for a while. If ice has formed on the walls, it is not recommended to remove it by force. Since we can cause mechanical damage to equipment.
After the equipment is completely defrosted, we wipe its walls with special means. Powder abrasive mixtures should not be chosen. Better opt for helium pastes.
Wipe the refrigerator dry with a clean cloth, ventilate it for 5-10 hours.
We plug the unit into an outlet and continue to operate it.

In some models of refrigerators, light bulbs in the backlight often burn out. Replacing them should not be difficult. It is enough just to unscrew the bolt holding the cover, remove it and unscrew the burned out light bulb. In its place, a new lamp is screwed in, the power of which should not exceed 15 W., and fix the shade in place.

Before proceeding with the repair of refrigeration equipment, it is necessary to diagnose it in order to understand whether it is possible to cope with the breakdown on its own or it is worth resorting to the help of specialists.

To diagnose equipment at home, you will need to prepare a universal tester and a screwdriver. Diagnostics begins with determining the quality of the voltage in the network. If it is 220 W, then everything is normal. If the voltage is less than this indicator, this can become the main reason for the failure of the household appliance.
Next, we carefully examine the cord and plug of the unit for integrity. It should not have defects, it should not heat up during operation.
Next, we inspect the terminals on the compressor. It is better to do this with the equipment disconnected from the network.
We inspect the compressor, which is located at the lower rear of the refrigerator. It must be free of defects and damage. After visual inspection, we check the winding. Disconnect flexible wires before inspection. It is necessary to check the winding circuit for continuity using a tester.
After that, you can proceed to diagnostics of small parts - the temperature sensor. To do this, use a screwdriver to remove and disconnect the wiring. Each wire is tested for functionality with a tester.

All malfunctions of refrigeration equipment are divided into two parts:

The inner chamber is not cooled during normal engine start. Most often, the breakdown lies in the main components of the equipment.

The unit does not turn on or turns on for a short time and then turns off. Here, the problems are associated with a malfunction of the electrical circuit of the household appliance.

In the first case, only highly qualified craftsmen should be engaged in repairs, since diagnostics and repairs can only be carried out with the help of special equipment and long-term skills.But if the electrical mechanism of the unit is out of order, then you can solve the problem on your own - after carrying out diagnostics, identifying the causes of the breakdown and replacing the failed spare part.In conclusion, I would like to note that every unit, even from a world-famous manufacturer, may stop working at some time. To repair a refrigerator, you need to figure out what the matter is, purchase the necessary part and stock up on free time. If you do not have special experience in the repair of household equipment, it is better to contact the masters of their craft, who will solve all problems quickly and efficiently.It is necessary to determine the reasons for the breakdown of the refrigerator.

This is especially true for refrigerators with the Nofrost system with complex systems of sensors, heaters and cold air circulation. Do not repair the refrigerator yourself. Trust it only to professionals, who will perform all operations efficiently and will certainly provide you with a guarantee.Sooner or later, the refrigerator starts to work incorrectly, of course, in this situation you need to find out what the problem is. Without thorough diagnostics, it is impossible to restore the operation of the device, if you cannot diagnose yourself - call a wizard who will immediately replace the broken part.Automatic devices used to operate the refrigerator:

Thermoregulators are sensors that keep the set temperature inside the refrigerator at an optimal level;

Start relay - is responsible for automatically turning on the motor winding when the refrigerator is turned on;

Protective relay - monitors the voltage so that there are no failures during the winding of the motor;

Cleaners - removes snow and ice that impairs evaporator performance.

Do not forget that for the refrigerator to work correctly, you need to maintain the voltage of electricity in the range from 200 to 240 volts. If the voltage is too low or too high, emergency operation will be activated. Many people forget about this, and look for a problem elsewhere, but before diagnosing, first of all, you need to check the voltage of the mains. Get a voltage tester, it is very cheap. Next, fix the test leads inside the socket contacts, but be careful, you can only hold on to the insulation on the test leads. After this procedure, you will receive detailed information about the strength of the voltage in the mains.Most often, the voltage is within reasonable limits, but the problem persists. It is quite possible that this is due to a malfunction of the plug, or a malfunctioning power cord. Replace the plug and power cord and the refrigerator will start working as well as before.If you have replaced, and the indicator light comes on, then the breakdown is related to the thermostat. Look for the two wires that lead to the temperature controller, and then remove from the terminals and close them tightly. Using this action, you can check the operation of the thermostat, it will react to the connection and turn on, but it will still have to be replaced.But if the problem persists this time, you need to test the defrost button, if there is one in this refrigerator model. If this time the problem persists, check the rest of the refrigerator appliances that are powered from the mains. Use an ohmmeter to test the protective and starting relays, there are often cases when they are combined in one case. If you notice a break, get rid of the broken part and replace it with a new one.The problem is compounded if the refrigerator motor-compressor is faulty. It cannot be repaired, so the entire compressor must be replaced. Do not try to repair the motor-compressor yourself - it is useless, you will only permanently ruin it. Call a professional technician, he will solve the problem in a short time.Usually, this problem is associated with the following malfunctions: a malfunction in the motor-compressor, freon leakage and a change in the temperature balance due to malfunctions in the thermostat. If the condenser, which heats up to at least 70 degrees Celsius, maintains a low temperature even when the compressor is running for a very long time, the problem is freon leakage. In this situation, it is very difficult to find the place where the leak occurred. You must purge the refrigerant from the system and then pump in air at high pressure. In the place where the leak has occurred, a strong air pressure will be felt. Charge the refrigerator with refrigerant, seal the leak, but be careful. The best option is to call the master.If you feel that the problem lies in the malfunctioning of the thermostat, replace it and check how the refrigerator is working correctly. You can also give the thermostat for regulation. It is almost impossible to diagnose problems inside the motor-compressor, as well as to eliminate them. Call the wizard if you suspect a compressor problem.Sometimes there is a more ambiguous problem: the thermostat works, but the refrigerator does not freeze as well as we would like. Replace the thermostat, if this does not help, check the refrigerator. For example, the problem may be leakage when the elasticity and shape of the sealing rubber changes greatly. The quality of the compressor drops noticeably, because warm air from the room enters the chamber. The problem is solved very quickly - restore the seal, and install a new sealing rubber. If the problem persists, try checking the thermostat adjustment, it is not uncommon for the temperature to be set too high or too low. Do not forget that in modern refrigerators everything is automated with special microcircuits, which can only be understood by a qualified specialist.Most people neglect the refrigerator, they believe that it is enough that it performs its functions and defrosts on its own. Rarely do people read the instruction manual and the operation manual, and very much in vain - it is possible to prevent possible problems.First, the refrigerator needs to be cleaned, both inside and out. To do this, you need a regular sponge or a rag soaked in disinfectant. Keep in mind that refrigerator cleaners are available at any hardware store. If there is an opportunity to purchase detergents from the same manufacturer - buy. They not only clean the refrigerator from dirt, but also improve the smell inside the refrigerator.Also, do not forget that not all refrigerator models are equipped with an air purification system, so you need to plan in advance for the purchase of a charcoal filter or a means to improve the smell.Secondly, you need to clean the refrigerator very carefully. It is undesirable for water to get under the shade of a lighting lamp or a thermostat, which is located inside the outer panel. It is usually in that position if you purchased an electromechanical refrigerator. In order not to damage the seal, you need to clean it with water, without using preparations containing chemicals. It is much easier to clean the outside of the refrigerator, pay special attention to those areas that you often touch with your hands.Do not wash the stainless steel refrigerator in the usual way. Despite the fact that it is a very attractive and high-quality material, it requires careful maintenance. Read the instructions to find out what product can be used to clean the refrigerator. If you did not find information, go to the company's website or study the forums where people leave feedback on the operation.After external and internal cleaning, the refrigerator must be dried. Use a dry flannel cloth. Of course, the back of the refrigerator also needs to be cleaned, but due to the huge amount of dust, doing this with a rag is very unpleasant and problematic. Very gently vacuum the back panel with a medium suction setting. When the refrigerator is completely dry, plug it in.
