it is necessary to heat the compressor and strike it with a rubber mallet!
When the compressor fails, the high vapor pressure refrigerant is no longer condensed. Without a phase change of the refrigerant is refrigerator will not cool.
Before removing the compressor from a refrigerator or other appliances, you must 'reclaim' the refrigerant. This is done by connecting a compressor-pump on the access connection and pumping the refrigerant into an approved storage tank. once the refrigerant is out of the system, you crimp & cut the lines going into the compressor. There will be compressor lube in the compressor; don't spill it or let it leak out.
A refrigerator compressor is the center of the refrigeration cycle. It works as a pump to control the circulation of the refrigerant, and it adds pressure to the refrigerant, heating it up. The compressor also draws vapor away from the evaporator to maintain a lower pressure and lower temperature before sending it to the condenser.
compressor runs quieter than usuAL and overheats
The compressor compresses the refrigerant gas. This raises the refrigerant's pressure and temperature, so the heat-exchanging coils outside the refrigerator allow the refrigerant to dissipate the heat of pressurization.
Typically it is either the compressor has gone bad or there is a coolant leak or it has low/no refrigerant
If the compressor is running, either the compressor has an internal fault or the refrigerant has been lost. If the compressor is not running the thermostat or the compressor may have failed. If the compressor is getting hot and switching off at regular intervals, the refrigerant has been lost. In any case a refrigeration engineer visit will be needed to prove the fault.
Adding refrigerant to a compressor is a precise job to take on, and it is important to know exactly what you are doing. Attaching the Freon kit, turn on the compressor, and adding the refrigerant are the steps to adding refrigerant to a compressor.
Refrigerant filled within compressor, condenser and evaporator has leaked not allowing thermostat to switch off the compressor or in rare cases thermostat itself is damaged.
Centrifugal Compressor and Rotary Compressor is preferred with refrigerant R-113.
