GE Refrigerator Defrost Limit Thermostat WR50X134 AP2071272 PS303484 EA303484

Refrigerator Defrost Limit Thermostat – GE

The defrost limit thermostat is a safety device that cuts power to the defrost heater when the evaporator coils reach a safe maximum temperature, preventing overheating. When it fails open-circuit, the heater never activates and frost builds up on the coils. This direct-replacement thermostat restores safe, effective defrost operation.
