12729128 Refrigerator Defrost Heater

Description: The Defrost Heater is an OEM part for Whirlpool refrigerators. This part prevents the build-up of frost and ice on the evaporator coils. By periodically heating up to melt away frost, this component ensures that air can flow freely through the coils, maintaining the refrigerator's efficient cooling performance.  Causes of a bad defrost heater can include electrical issues, such as a blown fuse or faulty wiring, wear and tear over time, or a malfunction within the heating element itself.
