Samsung DA47-00243K Refrigerator Bimetal Defrost Thermostat

The Samsung DA47-00243K Refrigerator Bimetal Defrost Thermostat is a temperature-sensitive safety device designed to regulate your refrigerator’s automatic defrost cycle and prevent overheating. Installed on the evaporator coil, it monitors coil temperature and automatically shuts off the defrost heater once a preset temperature is reached. This bimetal thermostat operates by using two bonded metals that expand at different rates, opening or closing the circuit as temperatures change. By controlling heat during defrost cycles, it helps protect internal components, reduce the risk of frost buildup, and support consistent cooling performance. Reliable and precise, it contributes to efficient operation and helps extend the overall longevity of your refrigerator.
