In detail: DIY repair of refrigeration compressors from a real master for the site my.housecope.com.
“How to repair a refrigerator motor-compressor? If you do not know what a compressor is and what it is for, read the information below. "
The motor-compressor is one of the most important units in the "body" of the refrigerator. Therefore, its breakdown completely paralyzes the entire apparatus, and further performance depends only on high-quality and professional repair. As much as you would like to repair this component yourself - this is an overwhelming task. Only a master of the highest category who has extensive experience and the necessary set of professional tools will be able to eliminate the malfunction.
In some cases, the motor can be repaired, but it is not always profitable, it is because of this that it is most often more profitable to replace the refrigerator motor.
A compressor is a complex electromechanical device that compresses and pumps refrigerant vapors in a refrigerator. When the vapors are compressed, their condensation is observed, after which the liquid flows into the evaporator, where evaporation occurs and heat is absorbed from the chambers. Modern refrigerators come in one, two and even three - compressor, although a refrigerator with three motors in stores is not often found.
In great demand use two-compressor unitsbecause they are the most reliable and economical in terms of energy consumption. If one compressor provides cold to the entire refrigeration cabinet with two compartments, then the two compressors work independently of each other, and each pumps the cold into the chamber assigned to it, be it a freezer or a refrigeration compartment. If one of the motors is out of order, you need a professional repair of the refrigerator motor-compressor.
Signs of a malfunctioning motor:
Failure of a motor-compressor is a serious problem, because its replacement or repair will cost a little more than repairing some other components. The main thing is to prevent damage in time, so you can save on repairing it. In order to quickly respond to refrigerator signals, you need to know a few simple signs that indicate a compressor malfunction.

• The motor does not turn on or off after a certain time interval. • Excessive noise during compressor operation, strong vibration or rattling. • Exceeding the temperature regime in the refrigerating chamber.
If you notice one of the signs, then there is cause for concern.
You need, as soon as possible, to call the wizard at home to carry out in-depth diagnostics. After diagnostics, the specialist will be able to establish the exact cause of the malfunction and determine the degree of its criticality.

“Is the motor-compressor defective? Our specialists will quickly and efficiently repair it with a subsequent GUARANTEE. Only original components and spare parts for all brands and models of domestic and imported refrigerators. "
Often, the repair of the refrigerator motor is required through the fault of the user himself.The fact is that some models are equipped with an additional useful function "Super freeze" or "Fast freeze". This function helps to freeze the product in a short period of time so that it does not lose its taste and useful properties. Using this function, the hostess simply forgets to turn it off, as a result of which the engine runs at full power at an exhausting pace, and this has a detrimental effect on its performance. The consequence of this is complete failure.
When examining the device, the master, most likely, will decide that the motor needs to be replaced, and each client thinks independently to agree with this or not. As costly as replacing a refrigerator compressor is, it is still cheaper than buying a new refrigerator. A less expensive type of repair should be called the elimination of noise, rumble and other unpleasant sounds when turned on. This is solved by a simple action - adjusting the suspension of the motor casing. To do this, you just need to adjust the suspension bolts and tighten them well. Rattling can be emitted by the relay if its position is unstable. In this case, the master will carefully and competently put it in its place, in order to avoid closing the contacts. Some cases imply a complete replacement of one of the components, but this can only be determined after a professional examination and diagnosis. You do not need to rely on your own strength.
Most of the cases when the user interferes with the internal structure of the refrigerator ends in failure, and, as a result, the subsequent overpayment for repairs, as well as a high probability of electric shock, which is unsafe for their own health. It is better to immediately seek the help of specialists and rejoice in a positive and lasting result.

Having made a step-by-step diagnosis of your Atlanta, have you established that the cause of the breakdown is in the compressor?
From the school physics course, we know about the structure of the internal combustion engine. The compressor functions in a similar way. The scheme of his work for Indesite or Atlanta is the same. A piston and valve system compresses the freon, sending the heated refrigerant to the condenser. There it turns into a liquid state, enters the capillary expander. The compressor compresses the freon, then cools the gas in the condenser, allowing it to circulate in the refrigeration system. The process is continuous and cyclical. The compressor is switched off, including from time to time to perform the refrigerant compression function.
Internal combustion engine device
What kind of refrigerator do you have - a Belarusian Atlant or one assembled according to the Italian patent Indesit, they all have the same motor, a similar arrangement of internal circuits.Reciprocating compressors are used in Atlanta and Indesite. The piston compressor is equipped with a vertical shaft electric motor. The structure is insulated with a sealed casing. The included motor starts the crankshaft, which rotates and moves the piston. The refrigerant is pumped out of the evaporator by the piston and pumped into the condenser.
Repair of refrigerators and replacement of the compressor can be done by yourself, having established 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 for no reason when the refrigerator is started? It is better to leave the replacement of the refrigerator compressor motor to professionals.
Refrigerator compressor repair
But you can try to replace the entire compressor.
Check out the video and photo of the step-by-step process of replacing the refrigerator compressor with your own hands.
Then prepare the necessary tool:
oxygen-propane burner;
two valves: for piercing and withdrawing refrigerant;
leak detector;
electronic thermometer;
small pipe cutter;
filter drier:
copper tube 6 mm;
solder;
flux;
pinch pliers;
Hansen clutch;
charging cylinder;
storage tank for freon;
new compressor.
Observe safety measures. Do not start work with the device turned on. The repair equipment must be grounded. Work is done with gas - the room must be well ventilated. Free the refrigerator so you can easily lift and turn it.
When replacing the compressor of the Atlant refrigerator, any other refrigeration device, it is necessary to slightly extend the compressor. Having lifted 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 a hose connected to it from the cylinder, unscrew it for 30 seconds. The gas will collect in a container.
Solder a copper tube in place of the broken tube. A gas torch is used here, in the absence of a torch, a soldering iron will do. An incision is made on the capillary expander a few centimeters in order to break off the tube and unsolder the filter from the condenser. The compressor is connected to the refrigeration unit with two pipes (one for pressure build-up, the other for removing excess gas).
It must be unsoldered 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 starter relay. Dismantle the compressor and remove it from the refrigerator. Strip the piping before brazing the new compressor.
When installing a new compressor, all steps are repeated in reverse order:
Your refrigerator is ready to go, start the engine. Then you need to check the functioning of the relay. If it starts, then you have completed the task.
