Based on customer reports and repair data, this part commonly fixes these issues:
A frozen freezer defrost drain can be caused by the freezer temperature being too cold. If the temperature is significantly below 0° Fahrenheit, you should use a multimeter to test the temperature sensor for appropriate changes in resistance as the sensor cools down or heats up. If the resistance doesn't change or there's no resistance at all, the temperature sensor is defective and will need to be replaced.
