Refrigerator Defrost Thermostat for GE WR50X10025 AP3190397 PS303445 L58-30*F

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 open-circuit, frost builds up on the coils, blocking airflow and causing the refrigerator to stop cooling. This direct-replacement thermostat restores proper defrost cycling.
