How to install a new compressor on the refrigerator. Repair and replacement of the refrigerator compressor: features and recommendations. Stage # 6 - we start the refrigerant into the system

The motor-compressor is the "heart" of the refrigerator, one of its main parts. Unfortunately, motor failures are not uncommon. He suffers from time, and from power surges, and from too intense work. A faulty motor cannot be repaired (except in the case of jamming), therefore, in the event of a breakdown, it is replaced with a new one. Motor installation - not an easy task, which, in addition to “removed and installed”, requires the system to be evacuated and refilled with freon. You can't deal with it on your own. Entrust the replacement of the compressor to the specialists of "RemBytTekh", and they will promptly perform the work - already within 24 hours after receiving the application!

Refrigerator compressor replacement prices

The cost of replacing the motor is from 1900 rubles depending on the brand and model of the refrigerator. This includes only the work of a specialist, a new motor and filter drier are paid extra.

*Prices are indicative. The master will be able to name the exact amount after a complete diagnosis of the refrigerator.

Compressor replacement procedure

• Dismantling a faulty motor-compressor. The master will cut and break off the filling tube through which the system is filled with freon. This tube will be needed for the new compressor. Then, at a distance of 20-30 mm from the filter-drier, cut off the capillary tube so that freon leaves the system. After the refrigerant evaporates, the master removes (or cuts off) the suction and suction tubes from the faulty motor, they are soldered at a distance of about 10-20 mm from the compressor. Next, it remains to unscrew the motor mounts to the refrigerator body and remove the motor.
• Mounting a new motor. The master will fix the motor in the housing and dock all the pipes of the refrigerator (suction, suction and filling) with the corresponding pipes on the compressor. Then solder the joints of the tubes with the motor.
• Replacement filter drier. The third stage changes the zeolite cartridge, which is also a filter drier. The master will desolder or cut off the old one and solder the new one. Filter drier - small but very important detail. It prevents small particles and moisture from entering the capillary tube, which can damage the refrigerator. The filter drier must be changed each time the refrigerator cooling system is opened. Its cost in relation to the total cost of repairs is low. But keeping the old part in place can significantly reduce the life of the new compressor.
• Vacuum system. After sealing all the seams using a special pump, the master will evacuate the refrigerator, during which excess moisture is removed from the system.
• Filling the refrigerator with refrigerant. When refueling, the master will also check the tightness of the soldering of all connections.

After that, it remains only to return the refrigerator to its place, turn it on and enjoy the proper operation of your refrigeration unit!

How to determine that the motor-compressor of the refrigerator is out of order?

A broken compressor motor is one of the most serious problems that can occur in a refrigerator. However, do not be upset - because perhaps the reason for the failure of the unit lies in a completely different problem. The following are signs that may signal a compressor failure:

• Motor not running because it is burned out, the refrigerator is warm, but the light is on.
• Refrigerator turns on and off immediately, inside the refrigerator is warm. In this case, the compressor winding was broken, interturn short circuit or the motor just "wedges".
• A rare symptom of a broken motor - fridge running non-stop without turning off, while the temperature inside the refrigerator is slightly increased. Typical for compressors with a long service life. Due to wear and tear, the motor cannot build up sufficient pressure in the discharge tube and lower the temperature to the required value, even though it is constantly running.

Whatever the symptoms of a problem with your refrigerator, don't guess. It is better to immediately contact the specialists of "RemBytTech":

Replacing the compressor (motor) of the refrigerator is a complex and time-consuming process. Work on its replacement refers to a complex (major) repair. In order to replace the compressor (motor), you must first remove the refrigerant from the refrigeration unit, then replace the compressor (motor) itself and the starting relay, while during the repair process it may be necessary to replace some other worn-out components. After carrying out the above operations, the tightness of the system is restored using brazing. Then the system is freed from air and charged with a certain amount of a specific brand of refrigerant.

How much does it cost to replace a refrigerator compressor?

Minimum total the cost of replacing the compressor of the refrigeration unit in our service center - 7500 rub . The price depends on both the brand and the model of the refrigerator.

Below is the estimated cost of replacing the compressor of freestanding refrigerators of the most common brands.

Once again, we would like to draw your attention to the fact that estimated cost. Only the foreman or duty engineer (senior foreman) will be able to name the exact cost of replacing the compressor with your refrigerator model upon approval of the order.

Owners of refrigerators Samsung, Electrolux, Liebherr, LG, Bosch and other high-tech brands should be aware that an inverter compressor may be installed on their refrigeration units. The cost of replacing an inverter compressor is significantly different from the usual one. The minimum purchase price of such a compressor is $180.

In the photo below: inverter motor-compressor. As you can see outwardly, it is no different from piston crank or crank-rocker motor-compressors installed on the vast majority of refrigerators. To determine the inverter or conventional compressor (motor) installed on your refrigerator, as a rule, it is possible only after the diagnostics or by the serial number, product code of the unit.

Refrigerator compressor replacement - a job for a professional

Refrigeration units are different from other major household appliances durability, while still functioning daily. However, they are also prone to breakage.

At frequent drops The mains voltage is the first compressor for the refrigerator to fail. It is this mechanism that is considered the most important element of the system, driving freon through the pipes, due to which cooling is provided.

In this article, we will consider existing varieties compressor and analyze the reasons typical breakdowns. We also present detailed briefing by replacing it with your own hands.

A broken compressor promises significant expenses not only for the purchase of a new device, but also for the work of the master.

However, you can go the other way and make a replacement yourself. Whichever option is chosen, the first step is to select desired type compressor.

Collector blower

Obtaining information from sources innovative models refrigerators, you can find such a thing as a "normal" compressor. However, not everyone knows its meaning.

This term refers to a collector mechanism with a vertically mounted motor shaft. It is mounted on a spring mechanism and closed with a sealed box, thereby providing a high degree of sound insulation of the system.

In older models, a horizontal layout was used, which made the unit more noisy - the vibration was reflected throughout the body.

It uses the standard principle of operation and technology developed many decades ago - the blower operates until the set temperature is reached in the refrigeration unit, and then turns off.

Refrigeration units can be equipped with one or two manifold blowers. If there are two of them, then one maintains the temperature in the freezer compartment, and the other in the cooling unit. Now it is becoming less and less common to find two-compressor equipment.

Overview models are equipped mainly budget options refrigerators and this is their only advantage over other representatives of the species.

Inverter type compressor

The upgraded units are equipped with an inverter type of supercharger. A conventional compressor reaches its peak when it is turned off, and there are a lot of such repetitions per day, and accordingly, it is subject to rapid wear and a shortened operating life.

Whereas inverter devices work even with sufficient air injection in the chambers, periodically reducing the number of revolutions. The wear resistance of components is much lower, and, accordingly, the period of uninterrupted use is higher.

Linear view of the device

Innovative developments in imported technology involved the new kind superchargers - linear. The principle of operation is similar to the previous versions of the devices, but this type is much quieter and more economical.

Unlike conventional mechanisms, they do not have a crankshaft. Through action electromagnetic forces reciprocating movements of the rotor are provided.

New modern models cooling devices are presented in a layout with inverter-type compressors. They work measuredly and smoothly, without amplitude drops, which are the main causes of wear of the mechanism.

Linear superchargers are technically similar to the previous two analogues, but they have a number of significant advantages:

• less weight;
• high degree of reliability during operation;
• no friction in the compression plane;
• application at low temperature regime.

LG is considered to be the main ideologist who has taken up the active introduction of linear-type superchargers. Most often they are used in refrigerators with a system no frost having individual temperature controllers in different units.

Rotary plate blower

Rotary (rotary) horizontally or vertically positioned blowers are equipped with one or two rotors and are analogous to a twin-screw juicer, however, screw-type spirals are unequal.

Depending on the principle of operation, they are divided into two main classes: with a rolling and rotating shaft.

A gap is formed between the piston and the compressor housing with movable plates. Due to the eccentricity of the rotor, its value changes during the reproduction of rotations, thereby blocking the transition of the refrigerant from one zone to another

In the first case, the unit is represented by an engine shaft with a mounted cylindrical piston, located eccentrically relative to the center, that is, offset.

The rotation cycles are carried out inside the cylinder body. The gap between the housing and the rotor changes its dimensions during rotation.

In the place of the minimum opening there is a discharge pipe, the maximum - suction. To the reverse piston, in turn, a plate is attached by means of a spring, which blocks the space between the two nozzles.

In the second version, the principle of operation is similar with one difference - the plates are fixed and placed on the rotor. During operation, the piston rotates relative to the cylinder, and the plates rotate with it.

The general algorithm of the refrigerator

The functioning of all refrigerators is based on the action of freon, which acts as a refrigerant. Moving along a closed circuit, the substance changes its temperature indicators.

Under pressure, the refrigerant is brought to a boil, which is from -30 ° C to -150 ° C. Evaporating, it captures warm atmosphere located on the walls of the evaporator. As a result, the temperature in the refrigeration unit drops to the set level.

In addition to the main pressure device that creates pressure in the refrigerator, there are auxiliary elements that perform the specified options:

• evaporator, collecting heat inside the refrigeration unit;
• capacitor, displacing the coolant out;
• throttling device, which regulates the flow of refrigerant through a capillary tube and an expansion valve.

All these processes are dynamic. Separately, it is worth considering the algorithm of the motor and the principle of operation in case of its malfunction.

The compressor is responsible for the system regulation of differential pressure levels. The evaporated refrigerant is drawn into it, which is compressed and pushed back into the heat exchanger.

At the same time, the temperature indicators of freon increase due to which it passes into liquid state. The compressor operates with the help of an electric motor located in a sealed housing.

Having dealt with the device, we proceed to the analysis of the main factors of compressor failure, after which it will be necessary to dismantle it.

The main causes of blower failure

All problems in the compression unit are conditionally divided into two main groups: with a running and idle motor. The first option is as follows: when turned on, a sound is heard from the compressor, the light on the refrigerator is on. Accordingly, in another embodiment, the unit does not turn on at all.

Reason #1 - Refrigerant Leak or Thermostat Defect

Here the main reason may be the freon leak.

Conduct self-check you can in this way: touch the capacitor - its temperature will correspond to room temperature.

Inspection of the degree of heating of the condenser can reveal one of the reasons for the breakdown of the refrigerator - a refrigerant leak. In this case, the device will function, but the temperature in the chambers will not be maintained.

Another reason is also possible - failure. In this case, the signal about the wrong temperature regime simply will not be received.

Reason #2 - winding problems

If the unit does not turn on, then possible cause could be an open circuit in the compressor windings.

Such a situation can occur both on the working and on the launcher, or on both at once. When the refrigerator is connected to the network, the supercharger does not work, and the temperature of its block is room temperature.

Reason #3 - interturn short circuit

The device starts, but not more than a minute. And the body gets too hot.

In this case, the turns of the winding are closed, their resistance is reduced, an increased current passes through the relay unit. The relay turns off the supercharger, a click will be heard. After the starter cools down, it turns on the compressor again and so on in a circle.

Reason #4 - engine jamming

When turned on, the operation of the electric motor is heard, but there is no rotation, the compressor does not compress, the resistance of the windings is at maximum.

Reason #5 - broken valves

The loss of cooling capacity is due to defective valves.

As a result of such a breakdown, the unit operates without shutting down and does not create the proper level of compression, respectively, blocks refrigeration device not getting to the right temperature.

Often in this case, an uncharacteristic ringing can be heard. metal parts when functioning. You can find out by determining the degree of air supply.

You can confirm the presence of deformation of the valves by fixing the degree of air supply to the compressor. This will require a special device with a pressure gauge.

To make sure of the "diagnosis", you will need to cut off the filling pipe with a pipe cutter. We do the same with the capacitor filter.

Now, in their place, we connect a manometric manifold, turn on the supercharger and check the generated level of air compression - the norm is 30 atm.

Reason #6 - thermal sensor or start relay

It is also necessary to check for defects such elements as a thermostatic sensor and.

With such a failure, the compressor either does not turn on, or turns on for 1-2 minutes. When checking the resistance of the windings, the nominal values ​​\u200b\u200bwill be fixed.

Step-by-step self-replacement process

If the causes of malfunctions are not determined, the supercharger itself is subject to repair. And first you need to remove it from the refrigeration unit and check its performance.

Stage # 1 - we dismantle the supercharger

The compressor is located behind the refrigerator in its lower part.

During the dismantling process, the following tools will be used:

• pliers;
• spanners;
• plus and minus screws.

The supercharger is placed between two nozzles connected to the cooling system. With the help of pliers, you need to bite them off.

In no case should the pipes through which the refrigerant circulates be sawn off with a hacksaw, because in the process small chips will necessarily form, which, when they enter the condenser, will move through the system, thereby leading to a quick failure of its elements

The refrigerator is started for 5 minutes, during which the freon goes into a state of condensate. After that, a valve with a hose connected to the cylinder is connected to the filling line. Within 30 seconds, with the valve open, all the refrigerant will be discharged.

After we remove the relay block. Visually, it can be compared with a regular black box with wires coming out of it.

First of all, the top and bottom are marked on the launcher - this will come in handy in the process reverse installation. Having unscrewed the latches and removed from the traverse, we also bite the wiring leading to the plug.

We unscrew all fasteners together with the viewing device. We clean all the tubes for soldering a new device.

Stage # 2 - measure the resistance with an ohmmeter

In order to make sure that the component is working, we will perform an external inspection, as well as testing and checking its individual components. First of all, we inspect the condition of the motor. This can be done using a multimeter or ohmmeter.

As mentioned earlier, the power cable is initially checked. If it is a worker, we examine the supercharger itself. To do this, we use the tester.

The correct functioning of the compressor can also be checked using a handicraft method using charging: we put negative probes on the body of a 6 V light bulb. Plus, we connect the power winding to the upper leg and touch each of them with the light bulb base. When in good condition, they should all illuminate the lamp.

First of all, we remove the protective block and extract the contents, disconnect from the starting relay. Next, using the probes of the multimeter, we measure the wires in pairs.

The results obtained are compared with the table, which indicates optimal performance for this compressor model.

Data of a working device in standard version will be as follows: between the top and left-hand contact - 20 ohms, top and right-side - 15 ohms, left- and right-side - 30 ohms. Any deviations indicate breakdowns.

The resistance between the feedthrough contacts and the case is checked. Breakage readings (infinity sign) indicate the health of the device. If the tester gives any indicators, most often it is zero, there are malfunctions.

Stage # 3 - check the current strength

After checking the resistance, it is necessary to measure the current. To do this, connect the start relay and turn on the electric motor. With the tester's tongs, we clamp one of the network contacts leading to the device.

When working with a compressor, it is initially inspected for breakdown of the casing, since there is a possibility of electric shock if the winding gives voltage to the casing

The current strength must be identical to the motor power. For example, a 120 W motor corresponds to a current strength of 1.1-1.2 A.

Stage #4 - preparing tools and equipment

To replace a faulty refrigerator compressor, you need to prepare the following set of tools and materials:

• portable station for regeneration, filling and vacuuming;
• apparatus for welding or with a cylinder of MAPP gas;
• compact ;
• ticks;
• Hansen coupling for tight connection of the compressor with the filling pipe;
• copper pipe 6 mm;
• filter absorber for installation at the entrance to the capillary tube;
• alloys of copper with phosphorus (4-9%);
• soldering borax as a flux;
• freon bottle.

You should also focus on safety measures when working with repair equipment. First of all, you need to equip an isolating platform and turn off refrigeration unit from nutrition.

Having dismantled the old compressor, it is necessary to prepare and clean all copper pipes for subsequent soldering with a new device

After each filling with freon, before soldering, the room is ventilated for a quarter of an hour. It is not allowed to turn on heating devices in the room where the repair is being carried out.

Stage # 5 - we mount a new compressor

First of all, it is necessary to attach a new blower to the refrigeration block crosshead. Remove all plugs from the pipes coming from the compressor and check the atmospheric pressure in the device.

Depressurize it not earlier than 5 minutes before the soldering process. Then we dock the compressor pipes with the discharge, suction and filling lines, their length is 60 mm, and the diameter is 6 mm.

Now we remove the plugs from the filter-drier and install the latter on the heat exchanger by inserting a throttle pipe into it. We solder the seams of the two contour elements. At this stage, we put on the Hansen coupling on the filling hose.

Stage # 6 - we start the refrigerant into the system

For refueling refrigeration system freon to the filling line with a clutch connect the vacuum. For the initial start, bring to a pressure of 65 Pa. Having installed a protective relay on the compressor, the contacts are switched.

The evacuation process is the creation of a compression level below atmospheric in the cooling unit. By reducing the pressure in this way, all moisture is removed

Connect the refrigerator to the power supply and fill with refrigerant to 40% of the norm. This value is indicated in the table located on the back of the device.

The unit turns on for 5 minutes and the connecting nodes are checked for tightness. Then it needs to be powered off again.

The refrigerant is charged in a liquid state. The required amount is indicated by the manufacturer in the parameters of the refrigeration device located on the rear wall

Perform a second evacuation to a residual value of 10 Pa. The duration of the procedure is not less than 20 minutes.

Turn on the unit and completely fill the circuit with freon. At the final stage, we preserve the tube by clamping. We remove the coupling and solder the pipe.

Soldering of two pipes made of copper, is carried out by an alloy of copper with phosphorus (4-9%). Docked elements are placed between the burner and the screen, heating it to a cherry color.

The hot one is lowered into the flux and melted by pressing the bar to the heated docking area.

The control inspection of the solder joints is carried out from all sides using a mirror. They must be complete, without gaps.

The service life of the compressor declared by manufacturers is 10 years. However, its breakdown is inevitable.

In the event of a blower malfunction, you can replace the broken compressor yourself, having previously familiarized yourself with all the safety rules and the stages of the work ahead. Also for these purposes it is necessary to stock up with the necessary equipment.

If you have any questions about self-elimination breakdowns, ask our experts in the comments to this post.

The motor-compressor is the "heart" of the refrigerator, one of its main parts. Unfortunately, motor failures are not uncommon. He suffers from time, and from power surges, and from too intense work. It is possible to repair this part, but as a rule, repairs are extremely expensive, painstaking and cannot guarantee that the breakdown will not occur again. Therefore, if the compressor breaks down, it is usually replaced with a new one. Installing the motor is not an easy task, which, in addition to “removed and installed”, requires the system to be evacuated and refilled with freon. You can't deal with it on your own.

Compressor replacement procedure

• Dismantling a faulty motor-compressor. The master will cut and break off the filling tube through which the system is filled with freon. This tube will be needed for the new compressor. Then, at a distance of 20-30 mm from the filter-drier, cut off the capillary tube so that freon leaves the system. After the refrigerant evaporates, the master removes (or cuts off) the suction and suction tubes from the faulty motor, they are soldered at a distance of about 10-20 mm from the compressor. Next, it remains to unscrew the motor mounts to the refrigerator body and remove the motor.
• Replacement filter drier. The third stage changes the zeolite cartridge, which is also a filter drier. The master will desolder or cut off the old one and solder the new one. The filter drier is a small but very important detail. It prevents small particles and moisture from entering the capillary tube, which can damage the refrigerator. The filter drier must be changed each time the refrigerator cooling system is opened. Its cost in relation to the total cost of repairs is low.

• Filling the refrigerator with refrigerant. When refueling, the master will also check the tightness of the soldering of all connections.

Having made a step-by-step diagnosis of your Atlanta, have you established that the cause of the breakdown is in the compressor?

We remember physics

From the school physics course, we know about the device of the engine internal combustion. The compressor functions in a similar way. The scheme of his work for Indesit or Atlanta is the same. The piston and valve system compresses freon, sending the heated refrigerant to the condenser. There it passes into a liquid state, enters the capillary expander. The compressor compresses the freon, then cools the gas in the condenser, ensuring its circulation in the refrigeration system. The process has a continuous cyclic character. The compressor is switched off, turning on from time to time to perform the function of compressing the refrigerant.

What kind of refrigerator do you have - the Belarusian Atlant or the Indesit assembled according to the Italian patent, they all have the same motor, a similar device internal circuits. In Atlanta and Indesit, reciprocating compressors are used. The piston compressor is equipped with a vertical shaft electric motor. The design is isolated by a hermetic casing. The turned on motor starts the crankshaft, which, rotating, moves the piston. The refrigerant is pumped out of the evaporator by the piston and forced into the condenser.

Where to start replacing the refrigerator compressor with your own hands

Repair of refrigerators and replacement of the compressor can be done independently by establishing the cause of the malfunction. If the compressor heats up after being connected to the network, the thermostat relay is most likely out of order. Replacing the refrigerator compressor relay is carried out even by an amateur. Does the motor suddenly turn off when you start the refrigerator for no reason? Refrigerator compressor motor replacement is best left to the professionals.

But you can try to replace the compressor entirely.

What you need

Check out the video and photos step by step process do-it-yourself refrigerator compressor replacement.

Then prepare the necessary tool:

• oxygen-propane burner;
• two valves: for piercing and refrigerant withdrawal;
• leak detector;
• thermometer electronic;
• small pipe cutter
• filter dryer:
• copper tube 6 mm;
• solder;
• flux;
• clamping pliers;
• Hansen coupling;
• charging cylinder;
• freon storage tank;
• new compressor.

Observe security measures. Do not start work when the device is turned on. Repair equipment must be grounded. Work is done with gas - the room should be well ventilated. Free the refrigerator so that you can easily lift and turn it.

Work process

When replacing the compressor of the Atlant refrigerator or any other refrigeration device, the compressor must be slightly extended. Raising it, break off the tube filling the freon, having previously cut it with a file.

Then you need to release the gas. Turn on the refrigerator for no more than 5 minutes. The refrigerant will move to the condenser. Attach the piercing valve with the cylinder hose connected to it, unscrew it for 30 seconds. The gas will collect in a container.

Solder a copper tube in place of the broken tube. Here it is involved gas-burner, in the absence of a burner - a soldering iron will do. An incision of several centimeters is made on the capillary expander in order to break off the tube and unsolder the filter from the condenser. The compressor is connected to refrigeration plant two tubes (one for pressurizing, the other for removing excess gas).

It must be soldered from these tubes or cut off with a pipe cutter. The filter drier is cut off at a distance of 15 mm from the condenser. Remove the start relay. Dismantle the compressor and remove it from the refrigeration cabinet. Before brazing a new compressor, clean the piping.

When installing a new compressor, all steps are repeated in reverse order:

1. place the compressor in refrigerator, fixing it on the traverse;
2. plugs on the nozzles must be removed;
3. it is important to depressurize the unit 5 minutes before soldering;
4. when removing the plugs, check that there is no excess air pressure in the compressor (this will be indicated by the noise of the outgoing air;
5. gradually connect the discharge, suction and filling tubes to the compressor nozzles, the filling tube must be 6 mm in diameter and 60 mm long;
6. start soldering the seams on the tubes, adhering to the following sequence: filling, suction, discharge, make sure that the burner flame does not go inside the compressor nozzle;
7. after removing the plugs from the filter-drier, attach it to the condenser, connect the capillary tube to it;
8. solder the filter at the seams;
9. and put on the valve half-coupling of the filling pipe;
10. check the quality of the soldering of all seams, they should be smooth, without soldered spaces;
11. refuel with freon by connecting a vacuum filling station to the coupling and removing moisture from the system;
12. mount the start-up relay on the compressor by connecting the electrical wires;
13. turn on the refrigerator, fill the system with freon, leave for 5 minutes;
14. use a leak detector to check if the tightness of the seams is broken;
15. perform a secondary evacuation of the refrigerator, leave it to work for 20 minutes;
16. pinch the filling tube, remove the coupling, solder the tube.

Results

Your refrigerator is ready to go, start the engine. After that, you need to check the functioning of the relay. If it starts, then you have completed the task.

Having gained a positive experience with your own hands, you can now give advice if one of your relatives or friends has a similar problem. And in difficult times, you can earn extra money by performing the operation to repair the refrigeration unit, which is no longer difficult for you.
