GE Refrigerator Defrost Heater (WR51X30141)

The GE Refrigerator Defrost Heater is a heating element inside your freezer compartment that melts frost buildup off the evaporator coils during the automatic defrost cycle. It turns on periodically to keep the coils clear so cold air can circulate properly and maintain the correct temperature throughout the refrigerator.

The GE Refrigerator Defrost Heater can burn out over time due to normal wear, electrical surges, or repeated thermal stress from constant heating and cooling cycles. When the heater fails, frost accumulates on the evaporator coils and blocks airflow, causing the refrigerator to lose its ability to cool efficiently.

These symptoms can help you decide if a defrost heater issue matches your problem:

- Refrigerator or freezer not cooling as well as it should

- Thick frost or ice buildup visible on the back wall of the freezer

- Food in the refrigerator section is warmer than expected

- Fan runs but little or no cold air reaches the fresh food compartment

- Refrigerator runs constantly without reaching the set temperature

- Visible frost covering the evaporator coils behind the freezer panel
