- troubleshooting various components to try to resolve the issue. While some issues can easily be fixed with minimal effort, others will require that you call in a professional who is trained in refrigeration repair.
Noise Inside the Freezer
Noise originating inside the freezer can typically be attributed to the evaporator fan, which runs whenever the unit is actively cooling. If you notice a chirping, squealing, or groaning sound that comes and goes (rather than being steady), it may be an issue with the fan motor. To find out for sure, open the freezer door and hold down the light/fan switch if there is one. If the sound gets louder with the door open, you can be pretty sure that the fan is the cause. Unfortunately, there is no way to repair the evaporator fan motor–you must replace the part in order to resolve the issue.

Noise from the Back of the Refrigerator
Most noises that you notice will come from the back of the refrigerator, where most of the moving parts are located. If you have a self-defrosting unit, the first place you will want to check is the condenser fan. The condenser fan is located on the back of the refrigerator, often behind a thin panel. The fan can occasionally accumulate a buildup of lint and other debris, causing a buzzing or clicking noise. You can try to resolve the problem by removing the thin cover to access the fan, and then cleaning the fan of any debris using a soft bristled brush (old toothbrushes are great for this!). Once the fan is clear of dust or other materials, replace the cover and plug the refrigerator back in. If you still have noise coming from the condenser fan after cleaning it, you may have to replace the pa
