refrigerator Stinol with two motor - compressors

To have a complete understanding of the electrical circuits of refrigerators, we need to go back to the 70s of the last century, where in our domestic technical literature you can find a detailed description of all types of refrigerators of those years.

In modern circuits, we can observe: cold storage room thermostat with ground, temperature compensation switch, heater, overheating protection relay, compressor with ground, overcurrent protection device, door contact and lamp. the action of the electromagnet, at overcurrents, the rod in the winding is attracted to the poles of the magnetic circuit, the contact opens, and a break occurs in the electrical circuit. When the current stabilizes, the return spring brings the rod to its original position and the contact closes the electrical circuit.

refrigerator condenser coil

The overheating protection relay works on the principle of the bimetallic plate mobility until a certain heating, the temperature heating is set in a heating resistor that releases heat to the bimetallic plate, and a certain heating of the resistor creates a current.

We know from electrical engineering that the lower the resistance in the electrical circuit, the greater the current, which means the resistor has its own specific resistance to the temperature regime. So the plate was deformed under the influence of heat, - the contact opened.

The heating temperature of the plate has decreased - the plate has taken its initial position, - the electrical circuit is closed. The heater is made in the form of an ordinary incandescent coil. The compressor is installed in refrigerators, single-phase, with a squirrel-cage rotor. The circuit also has a lamp connected in parallel in the electrical circuit, with a connected contact on refrigerator door, the contact closes when the door is opened.

Refrigeration circuit operation

For floor-standing refrigerators, the refrigeration unit has a lower motor-compressor arrangement. The sealed refrigeration unit mainly consists of:

motor - compressor;
capacitor;
evaporator

and is a circulating closed system.

refrigeration circuit with two motor - compressors

Freon refrigerant is used for circulation. When the motor - compressor is operating, freon vapors are sucked from the evaporator through the suction pipe into the casing of the motor - compressor and then the freon enters the cylinder.

Further, hot vapors of freon from the compressor cylinder are injected under pressure into the condenser. Due to the small section of the capillary tube, the freon pressure in the condenser increases. The refrigerant condenses at high pressure and freon in a liquid state accumulates on the end turns of the condenser coil.

refrigeration unit device

Through a capillary tube from the condenser, freon enters the evaporator. Getting into the evaporator, the liquid freon begins to boil, since a low pressure is created in the evaporator. Heat is absorbed from the environment, that is, from the refrigerating chamber.

The absorbed heat, together with the refrigerant, is fed back through the motor-compressor to the condenser coil.

Refrigerator wiring diagram

This diagram contains the following connections:

thermostat TH1;
thermal relay RH1;
compressor CO1;
starting protective relay RA1,

- connected in series in an electrical circuit. Two light bulbs are connected in parallel in the circuit:

indicator lamp SL1;
refrigerator compartment lighting lamp L1

and a button for lighting the refrigerator compartment IL1.

The reasons for not turning on the refrigerator can be different:

the single-pole circuit breaker in the group panel is turned off,
the machine is turned off above the electric meter in the apartment,
there is no contact between the plug and the socket,
the temperature regulator in the refrigerator is not turned on,
the refrigerator overheat protection relay has tripped and you immediately turned on the refrigerator again.

A malfunction of the thermostat affects the operation of the refrigerator:

duration of work;
prolonged non-inclusion;
continuity of work.

Usually, this reason for a malfunction of the refrigerator thermostat is the oxidation of the contacts.

In the event of a breakdown, malfunction of the thermostat - you should disassemble it and clean the contacts of the bimetallic plate.

If the starter relay fails, it may fail:

starting winding of the motor - compressor;
working winding of the motor - compressor,

- depending on the nature of the malfunction.

starting protection relay for motor - compressor

wiring diagram for starting and protective relay

The protective relay is an overcurrent fuse for the motor - compressor motor.

A failure of the protective relay leads to failure of the electric motor or shutdown as such, the shutdown of the electric motor without the influence of the thermostat.

Or in other words, with a sharp increase in the current strength, a voltage surge in the electrical network and a malfunction of the protective relay, the stator windings of the electric motor burn out.

Also, for refrigerators, such a malfunction is typical as the frequent operation of the protective relay, which leads to the switching on and off of the motor - compressor without the participation of the thermostat.

Repair, with the subsequent installation or replacement of a motor - compressor for a refrigeration unit, is a more voluminous performance of work. In general, when carrying out the repair of the refrigeration unit, brazing and welding are used.

motor - refrigerator compressor

Steel and copper pipes are connected together by soldering with silver solder.

The cover of the casing of the motor - compressor is welded with a steel electrode.

Depending on the nature of the work carried out during the repair of the refrigeration unit, the following types of connections can be used:

tin soldering;
butt welding;
arc welding;
argon arc welding;
brazing with copper;
soldering with silver solder.

Such work, for the repair of the refrigeration unit, requires, in some cases, specialized conditions, that is, they are carried out in the workshop premises.

gas torch for brazing copper pipes

Evaporator and condenser coil made of aluminum, - connected to copper pipes through copper-aluminum transition pipes. The aluminum side of the pipe is TIG welded to the evaporator. The copper side of the branch pipe is soldered with silver solder.

copper and bronze solder fittings

Argon arc welding is performed with a special torch using filler material. The parts to be welded are pre-cleaned with a wire brush and degreased with gasoline.

When welding the casing of the motor - compressor, work should be carried out as quickly as possible so as not to overheat the cover with contacts.

For butt welding of individual parts, a 220V household welding machine is quite suitable.

welding machine FUBAGTR 220

The place of leakage of freon from the refrigeration unit is determined in a workshop, - under air pressure.

It should also be remembered that with reduced voltage in the electrical network, the contacts of the starting relay at the moment the engine is turned on, the motor - the compressor may not close, as a result of which the starting winding will not be connected. For this reason, the rotor will not be able to turn, and a short-circuit current will flow through the working winding. The electric motor in this example is likely to burn out.

The refrigerator is an important device that helps to make life comfortable and cozy. However, sooner or later, any home appliances start to work intermittently. Then the question of how to repair a refrigerator with your own hands becomes very relevant. The fact is that contacting the service, even if the price is affordable, sometimes turns out to be superfluous. However, first you need to understand the reason why the refrigerator is not working properly.

Almost any defect in the operation of the refrigeration unit can be repaired by hand. It is enough to pay attention to this issue and clearly present an algorithm of actions.

In order for household appliances to last a long time, they must be properly operated. This is especially true of refrigerators, which, as a rule, have many owners in the house.

The refrigerator should be at least five centimeters away from other items of kitchen furniture.
It is better to store food in closed containers, then they will retain their freshness, and an unpleasant musty smell will not appear in the refrigerator.
Defrost and clean the refrigerator regularly. This also applies to models equipped with the No Frost system.
If unpleasant odors appear in the refrigerator, use small containers of coffee or green tea - these products are excellent at absorbing corrosive aromas.

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:

Inexpensive, but reliable and easy-to-use, Don refrigerators can be found in many Russian homes. The peculiarity of the units of this brand is their resistance to voltage drops, which significantly prolongs their "life". But, unfortunately, power surges are not the only reason household appliances can fail. If you find that your Don also "malfunctions" or has stopped working altogether - contact the specialists of "RemBytTech"! Our masters will establish the exact cause of the breakdown, and quickly and with a guarantee will eliminate it, returning your Don refrigerator to full operation.

Most often, the following malfunctions occur in DON refrigerators:

The motor-compressor is out of order.

The motor is not working. The temperature in the refrigerator is above the specified rate. In this case, the light in the refrigerator compartment is on.

Fridge Don turns on and turns off immediately. At the same time, it is warm inside the unit, and the refrigerator compressor itself is very hot. In some cases, the machine can also "knock out". This suggests that, most likely, a short circuit of the motor winding has occurred.

There was a leak of freon from the refrigerator system.

It is necessary to eliminate the leak and refill the refrigerator with freon.

The temperature in the refrigerator and freezer compartments of the refrigerator is higher than the specified norm, since the freon remaining after the leak is not enough to cool to the desired temperature. At the same time, "trying" to lower the temperature to the set value, the compressor of the Don refrigerator works without shutting down.

In some cases, if freon leaks, the evaporator may freeze up or the refrigerator may leak.

The capillary line is clogged.

It is necessary to clean the system, refill it with freon and check the oil (if necessary, and replace it).

The Don refrigerator thaws and leaks, the temperature in the freezing and refrigerating chambers is higher than required. With a "complete" blockage, when a "thrombus" completely blocks the pipeline, the temperature in the refrigerator becomes room temperature. The motor-compressor runs continuously.

Engine oil that has thickened during heating, which is present in the system, can cause a “clot” to form inside the capillary line. As a result of its appearance, the circulation of the refrigerant through the system becomes difficult, which leads to an increase in the temperature in the refrigerating and freezing chambers. The motor runs constantly, "trying" to pump freon through the system and lower the temperature in the refrigerator.

* The table shows FULL PRICES for repairs, taking into account the cost of new spare parts and the work of the master.

Years of operation do not spare even truly reliable and high-quality household appliances. At the same time, non-observance of the operating rules can significantly reduce the service life of the refrigerator.Whatever the reason for the failure of your unit, do not postpone its repair until a more serious and expensive breakdown appears. It is better to contact "RemBytTech" immediately:

Our specialists will eliminate the malfunction within 24 hours after you leave your application.

In the refrigerators of the Russian manufacturer Don, high quality, affordable price and attractive appearance of products are harmoniously combined. Designed specifically for operation in Russian conditions, they have powerful compressors and are not afraid of power surges.

Units of this brand are loved by our hostesses for their original design. Along with the classic white and metallic models, in the Don product line you can find products with an exterior finish that imitates the texture of wood, as well as pistachio, jasmine or ivory refrigerators. Most models also provide an opportunity for the owner to move the door to any convenient side in order to organize the kitchen space as harmoniously and comfortably as possible.

Their functional content is not inferior to the appearance of the units - numerous shelves, boxes, containers will provide the most convenient storage of products, preventing the mixing of odors. One of the advantages of Don refrigerators is the presence of a special antibacterial coating on the inner walls of all models, thanks to which products with a short shelf life will retain their taste and nutritional value for a long time.

All DON refrigerator models are equipped with one compressor, require manual defrosting of the freezer compartment and have a drip defrost system for the refrigerator compartment.

DON refrigerators are produced in the Tula region, at modern production facilities. Today the Tula plant is equipped with modern European equipment, which makes it possible to produce refrigerators of various types: single-chamber, double-chamber, etc. DON refrigerators have a stylish design, high reliability and a wide range of functions. Moreover, they are quite inexpensive.

One of the important advantages of DON refrigerators is their resistance to surges in the electrical network. Refrigerators of this brand are equipped with Austrian ACC compressors, which are not afraid of such negative influences. However, sooner or later, any equipment fails, and DON refrigerators - not an exception.

Refrigerators of this brand have a completely standard design, so their repair does not cause great difficulties. However, only professionals should be consulted for troubleshooting.

The repair of these refrigerators should be trusted by professionals. In case of malfunctions in the electromechanical part, standard symptoms appear: extraneous sounds, accumulation of moisture inside the chamber, arbitrary shutdowns, inability to maintain optimal temperatures, etc. All these are just external signs that do not give an accurate idea of the malfunction.

Each apartment and private house has a refrigerator that works without interruption, and often breaks down at the most inopportune moment. Most often, serious expensive repairs are required, or even a complete replacement of failed equipment. Many turn to service centers, but some DIYers successfully repair the refrigerator with their own hands. In this case, it is necessary to have a good idea of the device of the units, to have the skills to handle tools and to strictly follow the established procedure.

Before proceeding with self-repair of the refrigerator, you need to accurately determine the cause of the breakdown. With correct diagnostics, you do not have to disassemble the entire refrigerator, but immediately gain access to the place of malfunction.

The refrigerator has stopped freezing food, or the operating temperature is insufficient for normal storage. Here, most likely, the compressor is faulty or the adjustments are set incorrectly, with violations.

The refrigerator does not turn on... This can happen for a variety of reasons. For example, a plug or cable that is bent or has received mechanical damage is often faulty. Such malfunctions are easily eliminated with your own hands, it is enough to replace the damaged part. Refrigerators often stop working due to problems in the electrical network. For normal operation of the unit, a voltage of 190 volts or higher is required. If this condition is not met, the device will simply not turn on. This problem is not a breakdown, as in this case the protective mechanism is simply triggered. You can solve the issue by installing a voltage stabilizer.

The button that turns on the defrost function does not work... Sometimes it sinks or stops working altogether. As a result, this leads to the impossibility of defrosting or canceling an already started defrosting. In this case, the old button is removed and replaced with a new element.

Serious attention is paid to checking electrical circuits. It is possible that the lack of cold is due to oxidation of the contacts that need to be cleaned. This problem most often appears as a result of moisture ingress and with prolonged use of the equipment. Because of this, all compounds are oxidized and contact is lost. Such a breakdown is eliminated by the usual stripping of the terminals and the unit begins to cool again.

The electrical circuit of the refrigerator will help to quickly detect the malfunction. Defective parts found, such as the start relay, are usually not repaired but must be replaced.

Most domestic refrigerators have similar devices and, accordingly, they have the same problems. As a rule, all malfunctions consist in too strong freezing, or in its complete absence. By and large, they also affect foreign models, so the principles and rules for carrying out repairs will be the same for everyone.

The lack of cold is most often associated with the leakage of freon from the cooling system and compressor. Usually this problem becomes visible to the naked eye. If the leak was not visually detected, the following steps must be taken:

You need to find a special sealed tube on the compressor and pump out freon through it.
Instead of freon, air is pumped under low pressure.
A characteristic hiss will be heard at the place of damage, which will indicate a leak. This place should be soldered, since other methods are not suitable here.

Sometimes in Indesit refrigerators the freezing becomes weak. This occurs as a result of freezing of the air exhaust and supply ducts. It is very easy to eliminate this defect by ordinary defrosting of the unit.

Sometimes the thermostat functions normally, but there is not enough cold to freeze food. This problem applies to all brands of refrigerators. If the compressor is in good working order and is operating normally, then the rubber gaskets installed between the chamber and the doors may be the cause. Worn seals simply do not seal the refrigerator compartment as needed. As a result of the resulting gap, the cold gradually goes out. The problem is solved by replacing the old seals with new ones. Fastening is done with epoxy or glue.

If refrigerators, on the contrary, begin to freeze very strongly. Most often this happens due to incorrect settings of the thermostat, when the factory settings are lost. The situation is corrected by adjusting this relay. However, this operation requires qualifications, so you will have to call the wizard from the service center to configure it.

Sometimes severe freezing occurs as a result of a refrigerant leak. This happens very rarely because in all other cases the compressor starts to freeze much worse. In this case, replacing the compressor is not required; maintenance is sufficient.

During operation, more serious problems may arise, in general, negatively affecting the operation of refrigeration equipment. For example, the refrigerator produces noise and strong vibration. This usually occurs due to improper installation of the unit, as a result, the electric motor is not provided with normal operating conditions.

Many refrigerator problems are caused by improper installation of the equipment protection relay. In such cases, it must be reinstalled correctly. This procedure should be carried out in full accordance with the scheme.

Malfunction in the form of an unpleasant odor. This happens when the drain pipe becomes clogged during long-term operation of the refrigerator. The connection is cleaned with water or compressed air.

There are some differences in the repair of one- and two-compartment refrigerators.In the second option, there may be more compressors requiring care and monitoring. Usually one part fails, while the other continues to function normally.

Thus, it is quite possible to repair the refrigerator yourself. Of course, only specialists can solve more serious problems. But even those faults that can be corrected at home will significantly save the family budget. The most important thing is to carefully study the operating manual, and then follow it during the repair.

Photo gallery: DIY refrigerator repairIf any malfunctions are detected, it is advisable to trust the repair of the refrigerator to professional masters, but a number of malfunctions can be identified and even repaired by yourself. The Land of Tips will tell you how to repair a refrigerator with your own hands.The sequence of actions for troubleshooting is considered for compressor refrigerators without the NoFrost system.A refrigerator is one of the most important household electrical appliances in the house of each of us, so even a daily “simple” refrigerator can turn into a host of problems. The list of the most common potential problems includes the following:

the refrigerator does not turn on

the refrigerator works, but does not "freeze"

refrigerator slightly "freezes"

the refrigerator is very cold

To begin with, you should remember the principle of the refrigerator. The refrigerator consists of a compressor, a condenser, an evaporator, connected by tubes. The so-called refrigerant circulates through the sealed piping system, i.e. a gas that has a low boiling point and evaporation: when expanding, it absorbs heat from the environment, and when it is compressed, it gives it off due to condensation. In most household refrigerators, freons act as a refrigerant; ammonia is often used in industrial refrigeration units.The gaseous refrigerant flows from the evaporator to the motor-compressor, where it is compressed, and then fed to the condenser. In the condenser, the refrigerant, heated by compression, cools down and becomes a liquid state.The liquid refrigerant under pressure enters the capillary tubes, and then into the inner cavity of the evaporator, as a result of which, after expansion and transition to a gaseous state, it absorbs heat from the walls of the evaporator. The inner space of the refrigerator compartment is thus cooled. Image - DIY fridge repair don

The refrigerator does not freeze: what to do

The cycle will be repeated until the temperature sensors in the refrigerator compartment record the desired temperature (it is set on the thermostat). After that, the thermostat opens the electrical circuit and the compressor turns off (to save energy consumption). When the temperature in the refrigerator compartment rises due to various external influences, the cycle repeats again.

For the refrigerator to work properly, the supply voltage must be within 200-240 V, otherwise the safety mechanisms of this electrical appliance will work. Therefore, before looking for a malfunction, you should check the voltage level in the mains. The check is carried out with a special measuring instrument, a voltmeter or a universal multimeter (tester). By installing the test leads to the contacts of the electrical outlet (only hold onto the insulated sections of the test leads!), You can find out the supply voltage in the network.

Do-it-yourself repair of Atlant refrigerators

If the mains voltage is within the specified range, a faulty plug or a faulty power cord is a possible cause of the problem. Replacing these elements with new ones should solve the problem.

If the voltage indicator light is on, then the cord and plug are in good order, it is necessary to check the thermostat.It is necessary to find two wires suitable for the thermostat, and, removing them from the terminals, close them together. If after this operation the refrigerator starts to work, then it is enough to replace the thermostat to continue the normal operation of the refrigerator.

If the thermostat is working properly, it is necessary to check the defrost button of the refrigerator, if any, in the same way.

If the previous measures did not help, then you must also check other elements of the refrigerator electrical circuit. With the help of an ohmmeter, it is necessary to "ring" the starting and protective relay of the refrigerator (sometimes the relays are assembled in one housing). If a break is found, the defective part should be replaced.

The motor-compressor is the most important element of the refrigerator, if it is faulty, then, as a rule, its complete replacement is required. Do-it-yourself refrigerator repair in the event of a compressor breakdown is impossible - only a professional can select and install a new compressor correctly.

Similar consequences are typical for several types of malfunctions: freon leakage, malfunction of the thermostat, malfunction of the motor-compressor.

In the event of a freon leak, the condenser, which normally should heat up (up to 70 ° C), remains cold even with prolonged compressor operation. It is difficult to find the place of freon leakage on your own - for this it is necessary to drain the refrigerant from the system and pump air into the system under pressure. The air jet will be felt at the point of leakage. The problem will be solved by refilling the refrigerator with refrigerant and sealing the leak - you need to call the master.

If you suspect a malfunction of the thermostat, it must be replaced with a known good one and the result of the work must be evaluated. Replace the defective thermostat or give it back for adjustment.

The malfunction of the motor-compressor can only be identified and eliminated by a specialist.

If the refrigerator "freezes", but weakly, then, perhaps, the previously described malfunction of the thermostat takes place. Actions in this case are similar to those described above.

Also, a slight "frost" can be a consequence of the depressurization of the refrigerating chamber - the sealing rubber on the door has lost its shape and elasticity. In this case, warm air from the outside can enter the inside of the refrigerating chamber, which reduces the performance of the compressor. The leaky "rubber" should be replaced.

The malfunction of the refrigerator, when the refrigerator is very "freezing", can be caused by improper adjustment of the thermostat - just set the knob of the thermostat to the "higher" temperature and the problem is solved.

The described malfunctions do not cover the entire list of possible malfunctions in the refrigerator. Do-it-yourself refrigerator repair becomes more complicated if the refrigerator is equipped with control microcircuits, etc. Only a specialist can provide assistance in this case.

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. Image - DIY fridge repair don

Among the entire set of household electrical appliances designed to facilitate the existence of a modern person, the refrigerator occupies a central place. The safety of the most valuable food products depends on its uninterrupted operation. Fridge breakage is a rare occurrence and therefore always unexpected.

Waiting for an invited repairman can drag on for several days, and the malfunction may turn out to be trifling. Therefore, each owner is advised to have an idea of the principle of operation of the refrigerator, to know the main reasons for its failure and to be able to perform some types of repairs with his own hands. The principle of operation of all household refrigerators is the same and is based on the transfer of heat by the working fluid (refrigerant) from the inside of the refrigerating chamber to the outside.

The design of any refrigerator includes a compressor, a condenser and an evaporator connected to each other by tubes, as well as elements of the electrical supply and control circuit. The compressor evacuates the gaseous refrigerant from the evaporator in the refrigerating chamber. Heat is removed from the refrigerating chamber together with the refrigerant. The refrigerant is then pumped into the condenser by the compressor. Passing through the condenser, the working fluid is cooled and becomes liquid.

In this form, the refrigerant enters the evaporator again, where, when it turns into a gaseous state, it takes heat from the walls of the refrigerating chamber.Thus, in a closed cycle, heat is transferred from the interior of the refrigerator to the environment. The electrical part of the refrigerator device performs the functions of powering the compressor and regulating the temperature of the air inside the refrigerator, Refrigerator repair in Lipetsk produced in specialized service centers, as well as by individuals with extensive experience.

The main rule: competent operation is the key to the reliable operation of the refrigerator. Do not forget to carry out all types of maintenance prescribed in the instructions for using it.

The most common breakdowns of refrigerators:

increased noise during operation;
the refrigerator "does not want" to turn on;
the refrigerator turns on, but does not "cool";
insufficiently low temperature;
the temperature in the refrigerator is very low.
Increased noise during operation of the refrigerator

Possible reasons may include the following:

1) The rubber mountings on the compressor are secured with transit bolts or damaged. It is necessary to loosen the bolts or replace the pillows.

2) Uneven arrangement of the refrigerator. It is necessary to achieve a strictly vertical position of the body by adjusting the height of the legs.

3) The compressor is touching a wall or furniture. Move aside the refrigerator.

4) The content inside is positioned incorrectly. Arrange to prevent rattling.

1) The voltage in the mains supplying the refrigerator must correspond to the passport data. Otherwise, protection will work. Therefore, first of all, you need to check the voltage level in the network with a voltmeter. 2)

2) If the voltage is within specifications, check the condition of the mains cable and plug. If faults are found, replace.

3) If the refrigerator does not work, but the light inside the refrigerator is on, you need to check the condition of the thermostat. To do this, you need to disconnect the wires suitable for it from the terminals and short-circuit them. If the refrigerator turns on, then the reason for the failure is in the thermostat. It is necessary to replace it for further normal operation of the refrigerator.

4) A possible reason for the failure to turn on is a breakdown of the defrost button, if it is provided in the design of the refrigerator. The state of the defrost button is checked in the same way as the thermostat.

5) If the measures taken did not reveal the reason for the failure to turn on, it is necessary to check other parts of the refrigerator's electrical circuit. Using an ohmmeter, the start-up relay is checked and, if an open circuit is detected, it is replaced with a new one.

6) If after all checks the cause is not found, check the voltage at the compressor terminals. It may not be receiving power due to poor connections. If necessary, the contacts must be cleaned by first disconnecting the refrigerator from the mains.

7) If after that the refrigerator does not turn on, then most likely the compressor is out of order. It needs to be replaced, but it is difficult to implement it yourself. In this case, you need to involve a specialist.

This video demonstrates a method for self-repair and replacement of a refrigerator compressor. Remember that doing a DIY repair requires a number of technical skills, the necessary tools and equipment, and the correct replacement compressor and refrigerant.

Possible reasons for such a breakdown may be as follows: refrigerant leakage, thermostat malfunction, compressor failure.1) Leaking refrigerant. In this case, the condenser will remain cold even if the compressor is turned on for a long time (during normal operation, the condenser should heat up). If the leak cannot be detected visually, you will have to drain the refrigerant and look for the leak by pumping compressed air into the system. The leak point found in this way is sealed and the refrigerant is topped up. The elimination of this kind of malfunction must be entrusted to a specialist.2) The suspected malfunction of the thermostat is detected in the following way. It is necessary to replace the "suspicious" thermostat with a new one and check the refrigerator in operation. If everything is in order, then the unusable part must be replaced or adjusted.3) A compressor failure can only be rectified by a specialist.1) The temperature on the thermostat is set incorrectly. It is necessary to set the required cooling temperature.2) Failure of the thermostat. It is necessary to check its serviceability.3) In the room where the refrigerator is used, the air temperature is high. Install the refrigerator in a room with normal temperature, or at a sufficient distance from a heat source.4) A lot of dust has collected on the condenser, which is why the refrigerant, passing through it, does not cool sufficiently. It is necessary to disconnect the refrigerator from the mains and remove the dust with a soft brush or vacuum cleaner.5) The backlight lamp in the refrigerator compartment is constantly on. It is necessary to adjust the work of the switch of this light bulb.6) The seal of the refrigerator door has lost its elasticity, and warm air penetrates into the refrigerator compartment. It is necessary, if possible, to replace the seal.If liquid food freezes in the refrigerator, it means that the temperature is very low. Possible reasons:1) The temperature on the thermostat is incorrectly set. It is necessary to set the adjustment knob to a lower cooling level.2) Faulty thermostat. It is necessary to check its functionality and, if necessary, replace it.3) The fast freezing mode is accidentally turned on, if it is provided in the design of the refrigerator. It is necessary to check and, if necessary, disable.
