How to Repair a Freezer That's Making Loud Noise

If you are hearing freezer fan noise from your frost-free model, the issue might be caused by the evaporator fan motor. This type of freezer has a fan motor which circulates air through the evaporator to be cooled. Over time, the fan motor parts can wear or lose lubrication, causing a humming, buzzing, or clicking noise in your freezer. To replace the fan motor, first unplug the power source to your freezer. You will then need to remove the grille or evaporator cover to access the motor. Simply unplug the wire harness connector and remove the mounting screws.

If your frost-free freezer is making a loud buzzing or humming noise, it could mean the evaporator fan blade is damaged. The evaporator fan cycles air over the evaporator coil to cool it. To access the evaporator fan to check for damage to the blade, look behind the air grille or evaporator cover, first disconnecting power to the appliance. The fan blade is typically attached to the motor shaft by a spring clip. Unclip the fan blade to replace it.
