Do-it-yourself refrigerator repair breakdown diagnostics

In detail: do-it-yourself refrigerator repair diagnostics of breakdowns from a real master for the site my.housecope.com.

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:

Not every consumer knows that the repair of any home appliances, including the refrigerator, can be done independently without contacting a service center. Even a novice master can deal with simple breakdowns. Today we will try to figure out how to replace the refrigerator thermostat with our own hands. And also let's talk about what kind of device it is and what are its characteristics and purpose?

Video (click to play).

First, let's figure out what it actually is. A thermostat is a device that monitors the t˚C in your refrigerator and gives signals to the compressor, causing it to turn on and off depending on the degree of cooling in the compartment. It works very simply. The thermostat is a relay. On one side of it there is a special hermetically sealed tube filled with freon. On the other hand, the contacts of the electrical circuit, with their help, the compressor is controlled.

Everything works very simply. The end of the capillary tube is attached to the evaporator. Since it is filled with a refrigerant, for example, freon, then with an increase in t˚C inside the refrigerating chamber, the pressure in it increases. This closes the corresponding relay contacts and turns on the compressor. After a while, t˚C in the refrigerator compartment decreases, the pressure in the bellows tube drops and the contacts open. The compressor turns off.

Another important component of the thermostat is the spring, which compresses and expands its contacts. It depends on her how and when they will work. For example, in order to open the contacts at a low pressure in the system (low t˚C), less effort is needed, for a large one - more. The tension of the spring is adjusted using the thermostat switch knob. This is how the temperature regime changes in the Atlant refrigerator and other models with mechanical control.

Some models of refrigerators are equipped with an electronic thermostat. It consists of a temperature sensor and a control module.In modern models, several sensors can be installed for each cooling zone. If your refrigerator has an electronic temperature control mode, it may require specialized knowledge to repair it.

Well, we have disassembled the device and characteristics of the device, we move on to the next question. In order to repair the thermostat with your own hands, you first need to find it.

This is not difficult to do. The thermostat is always associated with a knob or button for setting the temperature regime in the chamber. Depending on the refrigerator model, the thermostat can be installed:

inside the refrigerating chamber;
outside the refrigerator.

This arrangement is typical for earlier models of Atlant refrigerators and others. If you open the refrigerator, you can see a small plastic box placed on one of the panels. This is the thermostat. To get to it, you just need to remove the temperature selector knob and unscrew the protective case.

Modern refrigeration units are arranged a little differently. In them, the device we need is located outside the refrigerator chamber. It is usually located at the top of the refrigerator, above the door. But it may be in another place.
In any case, the principle is the same - the temperature controller is located in the same place as the switch knob. To get to it, you need to remove all protective parts.

Do we really need a temperature controller? Maybe the cause of the breakdown is completely different? Most often, the signs of a breakdown of a thermostat are obvious: (See also: Why the refrigerator does not freeze - what to do?)

the refrigerator works without stopping and does not turn off on its own;
the unit begins to freeze strongly in the refrigerator compartment, where, in normal mode, there should be, albeit a low, but still positive temperature;
the refrigerator shuts down spontaneously and no longer makes any sounds.

Each of these faults can be caused by the temperature controller. In order not to spend money on calling a specialist, we will try to fix the breakdown with our own hands.

To be sure that the temperature regulator is the cause of the malfunction of the Atlant refrigerator or any other, you need to do the following:

disconnect the refrigerator from the power supply;
remove all food from it and defrost it well;
move the thermostat knob to the “Max” position or turn on the freeze, if any;
place a thermometer on the middle shelf of the refrigerator compartment (not in the freezer), it is best if it also has a negative measurement scale;
turn on the refrigeration unit (empty, no food);
wait 2 hours, then quickly remove the thermometer and evaluate its reading.
On the "thermometer" you should see at least 6-7˚С. If this is not the case, repairs are imminent. And if the thermostat in your refrigerator is electronic, then it is unlikely that it will be possible to carry out repairs with your own hands.

There may be only 3 reasons:

broken thermostat;
the motor start relay has burned out;
the engine of the refrigeration unit burned out.

The last two reasons are, of course, very serious. But we are now interested in the first one. To make sure that you need to replace the thermal relay, you need to check it:

disconnect the refrigerator from the network;
find the location of the thermostat and remove the protective covers;
inspect the device carefully.

Most often, the temperature controller has three to four colored wires. One of them is usually yellow with a longitudinal green stripe. This is grounding. We won't need it, so set it aside to avoid accidentally snagging it. All wires that fit the body of the thermal relay, short-circuit each other directly.If, after turning on the refrigerator, you hear a steady hum of the engine, it means that the temperature regulator is out of order and you will have to replace it with a new one.
By the way, the wires suitable for the thermostat have the following purpose:

orange, red or black - connects the thermostat to the motor;
brown - zero, the wire leading to the outlet;
white, yellow or green - leads to a light indicating that the refrigerator is on;
striped yellow-green - ground.

If you find such a nuisance, several factors may be the reason. So first you need to do all the steps described in the first paragraph. If the thermometer readings were + 6 ° C or less, quickly turn the thermostat adjustment knob until the refrigerator is turned off.
If the refrigerator turns off, everything is in order. Not? It will be replaced. In the event that the refrigerator is turned off, we leave it to work without food for at least 5-6 hours. After that, we begin to mark the time intervals between turning the compressor on and off. For a properly operating refrigeration unit, this period should be approximately 40 minutes. If you did it less, "add" some coldness, that is, turn the switch a little to the right, clockwise.
If everything went well, you can load the groceries. Not? The temperature controller will still have to be replaced.

Do-it-yourself thermostat repair does not take much time. For example, let's take a refrigerator of the Atlant trademark:

remove the cover of the upper hinge and unscrew the bolts under it;
remove the refrigerator compartment door;
further, remove the plug in the refrigerator roof and unscrew one screw (most often it has a built-in hexagon);
we unscrew the screws holding the roof (located at the back) and remove it;
remove the temperature control knob;
take out the temperature regulator by unscrewing 2 self-tapping screws that secure the bracket;
change the node to a new one and perform all actions in the reverse order.

In principle, wherever the thermostat is located, its repair will look about the same:

get to the detail;
disconnect the capillary tube from the evaporator body;
carefully pull it out of the case;
disconnect the relay itself;
carefully insert the new bellows tube and secure it to the evaporator;
connect all the necessary wires and attach the relay in place.

If this is your first time doing this kind of work, take pictures of your every step with your phone or camera. The photos will help a lot when assembling, if you forget what and where was connected.

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 to answer these questions.Classic refrigerator (without No Frost system) works as follows:The motor - compressor (1), sucks in gaseous freon from the evaporator, compresses it, and pushes it through the filter (6) into the condenser (7).
Freon heated by compression in the condenser
cools down to room temperature and finally turns into a liquid state.
Liquid freon, under pressure, through the opening of the capillary (8) enters the inner cavity of the evaporator (5), turns into a gaseous state, as a result of which, it takes away heat from the walls of the evaporator, and the evaporator, in turn, cools the inner space of the refrigerator.
This process is repeated until
reaching the temperature of the evaporator walls set by the thermostat (3).
When the required temperature is reached, the thermostat opens the electrical circuit and the compressor stops.
After a while, the temperature in the refrigerator (due to external factors) begins to rise, the thermostat contacts close,
using the protective and starting relay (2), the electric motor of the motor-compressor is started and the whole cycle is repeated from the beginning (see point 1)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 who is familiar with the device of the refrigerator and has a minimum set of tools is able to eliminate most of the malfunctions not related to 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.

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 before 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 back of the refrigerator compartment (on the back wall). Do not lean food against it and do not forget to clean the water drain underneath.

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

If a refrigerator suddenly breaks down in your home, you cannot ignore this nuisance. Often a breakdown happens at the most unexpected moment. Calling a master can be expensive, but, alas, no money. There is only one way out - DIY refrigerator repair... The main thing is to correctly diagnose the breakdown and clearly follow the advice of professionals.

Creation of the first household model electric refrigerator happened in 1913. This model used highly toxic cooling agents... In 1926, Albert Einstein and Leo Szilard introduced the design of an absorption refrigerator that used harmless alcohol fuel.

In the same 1926, the Danish Christian Steenstrup presented a harmless and silent model of the refrigerator. General Electric Company patented this invention, after which already in 1927 the first known Monitor - Top model was released. More than a million refrigerators of this model have been sold.

Since 1930, freon has been used in domestic refrigerators. In the 1940s, freezers appeared in refrigerators. In the 1950s, the defrost function became available.

Before how to repair a refrigerator it is necessary to understand the basic principles of its structure and operation. Cold production is produced four main components:

A condenser is a unit responsible for heat transfer.
An evaporator is a mechanism that removes heat from a chamber.
A compressor is a unit that generates the required pressure difference.
Refrigerant (freon, freon) is a colorless gas that transfers heat to the condenser from the evaporator.

The operation of the refrigerator is coordinated by built-in electrical appliances:

start-up relay that regulates engine start;
thermostat responsible for automatic on and off;
compressor electric motor;
defrosting system that prevents frost formation on the evaporator;
door opening sensor, which is responsible for turning the light on and off when opening or closing.

The walls of the refrigerating chamber are cooled by a compressor, which, thanks to an electric motor, pumps out the refrigerant, and the condenser pumps this gas. Radiators cool the gas and return it to the evaporator. When the thermostat fixes temperature rise in the chamber, the relay starts the compressor. The refrigerant has a negative boiling point, which allows it to take away the available heat inside the refrigerating chamber, boil, give off heat to the outside world and turn into a liquid again.

If you have a need for Do-it-yourself Indesit refrigerator repair or troubleshooting models of any other brand, you can safely use the tips of this article for any modern refrigerators... We did not notice much difference in the principles of operation, troubleshooting and troubleshooting between different models.

Before how to fix a refrigerator yourself, you need to find out the exact cause of the breakdown. This will allow you to estimate the size Problems and the possibility of self-elimination. Maybe it will be technically impossible to make repairs with your own hands and you will have to use the services of a service center.

Before starting work, it is necessary to remind that any actions for the diagnosis and repair of electrical devices must be carried out, having previously stopped the current supply. Consider common refrigerator breakdowns, methods for diagnosing them, as well as the correct options for solving these problems.

The most serious problem that can show up during troubleshooting is compressor failure. We can confidently say that do-it-yourself replacement of the compressor in the refrigerator, like its repair, is impossible and, most likely, you will have to change the refrigerator.

To check the compressor's serviceability, you need to unscrew the bottom rear cover, under which it is located. You can immediately see the group of contacts with which the compressor is connected to the power supply. The green and yellow wires are ground, the first brown and blue are mains powered, the second brown and black are powering the compressor.

Disconnect all wires and close the two brown contacts. Then we plug it in. If the compressor does not work, you will have to buy another refrigerator.

The vast majority of modern refrigerators are equipped with a No Frost system. The next step in the diagnosis will be to check the fan that accelerates the cold air in the freezer. The fan is always connected to the compressor so that in the event of a fan breakdown, the evaporator tubes are not prematurely frozen.

It is necessary to open the freezer and remove the back wall with the fan located on it. It has only two contacts, you need to supply power to them.For this, a piece of any cord is quite suitable. If the fan does not work, it must be replaced.

The fuse is located in the freezer. It is a small metal cylinder enclosed in transparent plastic. It must be disconnected and checked with a standard tester, in case of malfunction, the fuse will need to be replaced.

The thermostat is responsible for maintaining the required temperature inside the refrigerator compartment. Depending on the temperature reading, the thermostat turns on and off the electric motor of the compressor. In the event of a breakdown, the refrigerator will either stop working or will work non-stop.

The thermostat is located inside the refrigerator compartment. It can be distinguished by the presence of a temperature controller. You need to remove the thermostat and short-circuit the wires that fit to it directly. In the event that the motor is running, the thermostat needs to be replaced.

The main reason for the failure of this relay is power outages. In this case, the refrigerator compartment simply stops working.

The relay is located on or near the compressor. It can be distinguished by its plastic body. A malfunction can be diagnosed by the presence of melted contacts or carbon deposits on the case. It is necessary to disconnect the relay, having previously fixed the connection diagram of the contacts. Replacing this part shouldn't be a big problem.

There are some types of faults that you can repair yourself. Image - Do-it-yourself refrigerator repair diagnostics of breakdowns

From this fact, we can conclude that there was a breakthrough of the drainage pipe. The drainage system delivers excess condensate volume to a special tank. If a crack appears in the pipe, condensation will flow to the bottom of the refrigerator.

It is necessary to pull out the rear panel at the bottom of the refrigerator compartment. Under it you can see a plastic tube connected to the drain hole. It is necessary to find the place of water leakage and carry out the soldering work. Alternatively, you can simply replace the pipe by hand.

Sometimes the drainage pipe will slip. In this case, you just need to put it in place.

It may also be necessary to clean the drainage pipe. The best way to do this is to use a soft, long-handled brush. Do not use metal-coated brushes or chemical cleaners to clean the drain.

The recommendations in this article are about diagnosing and replacing entire parts of your refrigerator. Only professionals can repair components such as a thermostat or relay. Probably, ordinary people do not need this, because today in every city there are many specialized stores where you can buy almost any part.

This article provides examples of the most common breakdowns. Of course, there are many nuances of diagnostics and repair that you can write a textbook about. You may not have received a comprehensive answer, how to repair a refrigerator with your own hands. Video on the Internet will help you understand the questions that arise.

Thanks for the advice. The current prices are inclusive of the head. The thermostat is broken. More precisely, after reading the article and diagnostics, I realized that the thermostat had broken. Now I can replace it. A master's challenge would hit the pocket.

In the "No Frost" system, the breakdown is immediately visible - there will be a lot of ice on the radiator. It will prevent air from entering the chamber.

Water flowed out of the refrigerator. No money for repairs. I will solder this pipe myself. I don't know if it will work out or not ...

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 clearing 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.

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;

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.DIY installation of screw piles: performing installation calculations, installation rules.
