Question and Answers

Q:

Why won't my freezer temperature get down below the low 20's?

A:

You may have a sealed system failure; it could be short on Freon or an inefficient compressor. Make sure the condenser coils are clean and that the condenser fan is running too. There should also be a cardboard panel sealing the back of the unit too. If the cardboard panel is not in place the condenser fan motor can not pull air across the condenser coils and cause a failure in cooling.

I recommend unplugging the refrigerator and remove the evaporator panel and disconnect the evaporator fan motor wires so the fan will not run. Turn the refrigerator back ON and leave both doors shut for 10-15 minutes and then open the freezer door and visually look to see if there is frost covering the evaporator coils from one end to the other end. It should have a light frost pattern covering the coils from one end to other end if the compressor and sealed system is OK. If you find only a couple of rows covered in frost would indicate a sealed system failure and would require a technician to tap into the sealed system and connect a set of manifold gauges to check the low side pressure of the sealed system.

Q:

I'm still having trouble; do you think that the t-stat that I just replaced is defective?

A:

Your details indicate a sealed system failure. You said that there was only a little bit of frost on the top 2 coils. In a properly working freezer all of the evaporator coils should be covered in a light frost. It is not a defective thermostat. You either have a sealed system short on Freon due to a sealed system leak or an inefficient compressor.

You will need to call a service technician to diagnose if the failure is the compressor or a sealed system leak.
