How to test a refrigerator defrost heater
![]() | Use our step-by-step refrigerator repair guide to learn how to test your defrost heater. Once you have diagnosed the problem we have the OEM replacement defrost heater that fits your appliance. Before you begin to test your defrost heater, make sure you disconnect the appliance's power supply. The easiest way to do this is to unplug the unit from the wall. Alternatively, you could trip the appropriate switch in the circuit breaker panel, or you could remove the appropriate fuse from your home's fuse box. Consult with an appliance repair technician if you do not feel you have the skill or the ability to successfully complete this repair.
