The 115-volt evaporator fan motor is in the back of the freezer section and circulates air over the coils. These coils will convert the heat into cool air, which is then circulated. If your freezer is noisy or too warm from the motor not working, you will need to replace this part. It is suggested to replace the thermistor when replacing the evaporator fan. This is a genuine OEM part – note the screw holes in the motor are not threaded from the factory, use your old screws. Please remember to disconnect the power to the refrigerator before starting your repair.
