Refrigerator not cooling? Find out how to troubleshoot problems

Hi, this is Wayne from Sears PartsDirect. Today, we're going to talk about a refrigerator not cooling. If you can’t hear your refrigerator running, the first thing you need to do is check for power. Open the refrigerator door and see if the light turns on. If the light doesn’t turn on, let’s check the power cord and the outlet. Obviously, you’ll want to make sure that 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 some other appliance that makes noise. If your outlet isn't working, you’ll need to have it repaired by a qualified electrician.

Frost Buildup Prevents Cooling

Once you’ve confirmed that your refrigerator is getting power, the next thing you will want to check for is excessive frost built up 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. This video will walk you through that process.

Compressor, Evaporator Fan Diagnostics

If there’s no frost on the evaporator coils, let's move on to some more advanced checks. Most refrigerators, like this common Kenmore model, have a diagnostic test mode that checks refrigerator operations. First, we'll check to see if the compressor and evaporator fan run in the test mode. To enter the diagnostic test mode on this Kenmore model, within 2 seconds, press the light switch 3 times and then press and hold it a 4th time until you hear a long beep. You're now in the test mode. If this doesn’t work on your model, check your tech sheet for instructions. You can usually find it located behind the bottom front grill or taped to the back of the refrigerator.

Press the door switch twice to start the compressor. The control beeps twice and then you should hear the compressor start. If you don’t hear the compressor turn on, check the start relay on the compressor. This video will show you how to troubleshoot issues with your compressor.

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. This video will show you how to troubleshoot problems with your evaporator fan.

Temperature Sensor Check

If the compressor and evaporator fan both work in the diagnostic test mode, you’ll need to check the thermistor, which is the temperature sensor. This video will show you how to troubleshoot problems with the temperature sensor.

To exit the test mode, within 2 seconds, press the door switch 3 times and then hold the switch down until the control beeps. Or just unplug the refrigerator.

Other Possible Problems

We want to help you determine the correct part needed to repair your refrigerator. Keep in mind it can be hard to diagnose the exact issue. Failures such as a broken condenser fan or the refrigerator being low on Freon, can also keep the refrigerator from cooling well. Don't hesitate to have a Sears technician diagnose and repair your refrigerator if necessary. Well I hope this video helped you out today.
