Hello Richard,

If the freezer is cold and the fridge side is warm, you need to check the evaporator coils to determine if they are frosted over. The defrost heater assembly turns on a few times throughout the day to melt away any frost that may have accumulated on the evaporator coils. If the defrost heater assembly is defective, frost will continue to accumulate on the evaporator coils, and the coils will become plugged with frost. If the evaporator coils are frosted over, the airflow through the coils will be restricted, causing the refrigerator not to cool. Since changing the Fan/Fan motor didnt help, check the evaporator coils to determine if they are frosted over. If the evaporator coils are frosted over, test each component of the defrost system like the defrost thermostat.

The defrost thermostat monitors the temperature of the evaporator coils. To determine if the defrost thermostat is defective, use a multimeter to test it for continuity. If the defrost thermostat does not have continuity when it reaches the low temperature of its operating range, replace it.

Also check the air damper control. It opens and closes to let the proper amount of cold air into the refrigerator compartment. If the damper does not open properly, it won’t let enough cold air into the refrigerator. Check the damper control to determine if it is broken or stuck closed.

Thanks for replying Richard. If the freezer coils are not freezing then the defrost system has no issues as well replacing and fixing the condenser fan, The problem could be a leak or compressor problem. First  check if the condenser coils are dirty, they won’t dissipate the heat effectively. As debris builds up on the coils, the refrigerator becomes less efficient, causing the refrigerator to work harder to cool down. If the coils are significantly dirty, the refrigerator will not be able to maintain the proper temperature. Check the condenser coils at the back of the refrigerator to determine if they are dirty—if the condenser coils are dirty, clean them then observe for  an hour if theres a good temperature change. 

Compressor Issue:

The compressor is a motor which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. If the compressor is not working, the refrigerator won’t cool. Before replacing the compressor, first check the condenser coils on the back of the refrigerator. If it has been done, use a multimeter to test the compressor for continuity. If the compressor does not have continuity, that could be the problem.

Just in case comptessor is okay, the last thing I can think of which is causing this issue is the Main control board. This might need to be replaced. Please let me know if you are already satisfied with the answer or have additional questions by replying to this message. I will be waiting for your response once you are done with the tests. Thanks.
