My Freezer Compressor Will Not Stay On [2012-03-20]

 

Precisely the refrigerator is made up of the Freezer Compressor , the pipes as heat exchanging unit both from inside and outside, the refrigerant and the expansion valve. If you ought to understand the working mechanism of the freezer compressor, you need to know about the refrigerant first. The refrigerant is primarily the liquid which undergoes evaporation for cooling the temperature inside the refrigerator. Pure ammonia is one form of refrigerant which needs just 32 degrees Celsius to evaporate.
Power
The most obvious problem, and easiest to fix, is when the freezer cord has become unplugged. Even though the possibility seems ludicrous -- after all, no one's been back there -- it's still worth taking a look because the compressor will not run without electricity. If it's still firmly plugged in, find the main breaker box and verify that a circuit has not been overloaded and tripped a switch there. After confirming that the appliance is indeed getting power, it's time to look inside.
Thermostat
Freezers come with an adjustable thermostat inside the cooling area or on the outside of the unit. If the thermostat is set too high, the compressor won't stay on because it won't detect that the temperature needs to come down. Maybe the setting was inadvertently changed when someone tossed a gallon of ice cream inside. If the thermostat setting appears normal, it's time to check the Low Pressure Compressor itself.
Compressor
The compressor is the football-sized lump of metal on the back, or sometimes underneath, your freezer. It should be easily recognizable and accessed. As a mechanical device, it is quite likely to become worn out or overheat and stop working or work sporadically. The tricky part is that a failure of other mechanical parts in the system, such as the evaporator or condenser, can show up as compressor problems. Something as simple as dirty condenser coils can cause the compressor to overheat and run poorly.
Considerations
If you determine that the compressor is the problem, there's a good chance that repairs would cost more than the appliance is worth, and you might be better advised to buy a new freezer. For the price of a service call, you can have a repair technician confirm whether or not the compressor is the culprit. Maybe you'll get lucky and find the problem is unrelated and easily remedied. Then again, you might learn it's time to take a trip to the local appliance store.
