Customer Questions and Answers for Defrost Heater (Refrigerator) by Ge

The defrost heater warms the evaporator during automatic defrost cycles to remove frost and ice, restoring airflow and cooling. Replacing a failed heater helps prevent frost buildup and maintain more consistent temperatures throughout the refrigerator.

• Melts frost from the evaporator coil during scheduled defrost cycles
• Helps maintain airflow and cooling performance between compartments
• Failure may cause heavy frost on the back wall/evaporator cover
• Can lead to reduced cooling, long run times, or fan noise from ice contact

• Disconnect power before servicing; wear appropriate gloves.
• Remove freezer shelves/ice maker as needed and the rear panel to access the evaporator area.
• Defrost any ice buildup and avoid damaging evaporator fins or wiring.
• Reuse original mounting hardware/clips as needed; check the defrost thermostat and control if frost issues continue.
