WP4344659 - Whirlpool Refrigerator Thermostat

The Whirlpool Refrigerator Thermostat (WP4344659) is a genuine part produced by Whirlpool for its refrigerators. This part is also compatible with other brands that utilize the same component design. Sometimes referred to as a temperature regulator, this thermostat plays a crucial role in ensuring your refrigerator maintains the right temperature.

The thermostat works by using a sensor bulb and capillary tube connected to the evaporator outlet. These components measure the cold air temperature within the refrigerator. When the air temperature rises above the set point, the thermostat activates the compressor and fans to increase cooling. Conversely, when the temperature drops, the thermostat deactivates these components, thus maintaining an optimal temperature within your appliance.

Additionally, a separate defrost thermostat, located near the evaporator, prevents the coils from overheating during defrost cycles. This part is a critical component in the refrigeration system of your appliance, acting as an on/off switch to control various parts based on the air temperature changes measured at the evaporator.

If your refrigerator is not maintaining the correct temperature, or if the compressor and fans are not functioning as they should, these could be symptoms of a failing thermostat. In such a case, the Whirlpool Refrigerator Thermostat (WP4344659) could be the replacement part you need.

Before purchasing, please ensure to verify your device's model number for compatibility with this thermostat.
