GE WR50X129 Refrigerator Defrost Thermostat

Refrigerator Defrost Thermostat – GE

The defrost thermostat monitors evaporator coil temperature and cuts power to the defrost heater once the coils reach the correct temperature. When it fails, coils frost over completely, blocking airflow and causing the refrigerator to stop cooling. This direct-replacement thermostat restores proper defrost cycle operation.
