The evaporator fan motor circulates air over the refrigerator coils. These coils will convert the heat into cool air, which is then circulated. This part is 115 volts, has a 3/16th-inch shaft and is just over three inches long. It is made of both metal and plastic, and is made up of black, white, and metallic pieces. This evaporator fan motor is a genuine OEM part. Please remember to disconnect the power to your appliance before starting the repair.
