There are a few different parts that could be to blame if your refrigerator isn't cooling. Your automatic defrost system may not be melting the frost off your evaporator coils. The compressor, which circulates coolant, may not be working correctly. Your evaporator fan may not be blowing cool air in your refrigerator. Or your thermistor may not be sending the correct temperature signals to your electronic control board, which controls all the major components. This video will walk you though some simple tests to help narrow down what's causing the problem and provide links to more advanced tests to figure out which part or wire needs to be replaced to get your refrigerator up and running.
1. Check for power
If you can’t hear your refrigerator running, check for power by opening the refrigerator door to see if the light turns on. If the light doesn’t turn on, make sure the refrigerator is plugged in and that the power cord isn’t damaged. Then make sure that the electrical outlet is working by plugging in a lamp or an appliance that makes noise like a blow dryer. If the outlet is broken, have it repaired by a qualified electrician.
2. Check for excessive frost
Check for excessive frost buildup on the evaporator, which can inhibit cooling. You may need to troubleshoot issues with the automatic defrost system if the evaporator is caked with frost.
3. Enter diagnostic test mode
Most refrigerators have a diagnostic test mode that checks refrigerator operations. Check the tech sheet for instructions. Look for it behind the bottom front grill or taped to the back of the refrigerator.
4. Test the compressor
Press the door switch twice to start the compressor. The control beeps twice and then the compressor should start. If you don’t hear the compressor turn on, check the start relay on the compressor.
5. Check the evaporator fan
To check the fan, press the door switch twice within 2 seconds and wait for the two beeps. Repeat this step 2 more times. The control beeps twice and then starts the evaporator fan. If the evaporator fan doesn't run, unplug the refrigerator and check the evaporator fan.
6. Check the thermistor/temperature sensor
