WPW10583800 - Whirlpool Refrigerator Thermostat

The Thermostat (WPW10583800) is a genuine part manufactured by Whirlpool for use in their refrigerators. This part is sometimes referred to as a temperature control switch or a cold control. The thermostat is a crucial component in ensuring your appliance maintains the correct temperature in both the fresh food and freezer compartments.

This thermostat operates by sensing the temperature in the refrigerator via a sensor bulb and capillary tube connected to the evaporator outlet. When the temperature rises above the set point, the thermostat triggers the compressor and fans to increase cooling. Conversely, when the temperature drops, the thermostat deactivates these components.

Additionally, a separate defrost thermostat, located near the evaporator, prevents overheating of the coils during defrost cycles. Thus, the thermostats act as precise on/off switches, controlling the refrigeration system's operation based on the air temperature changes at the evaporator.

Symptoms of a failing thermostat may include the refrigerator running constantly, the appliance not cooling properly, or the fridge cycling on and off too frequently. If you notice any of these signs, it might be time to consider replacing the thermostat.

Before purchasing this part, we advise verifying the compatibility of this thermostat with your specific Whirlpool refrigerator model number.
