12001937 - Whirlpool Refrigerator Thermostat

This Whirlpool Refrigerator Thermostat (12001937) is an essential component for regulating the temperature within your refrigerator. Manufactured by Whirlpool, this genuine part is compatible with a range of brands, including GE, KitchenAid, Maytag, International, Amana, Jenn-Air, and Crosley. The thermostat plays a critical role in maintaining the fresh food and freezer compartments at precise temperatures. It does so by utilizing a sensor bulb and capillary tube connected to the evaporator outlet to measure the cold air temperature. This allows the thermostat to control various components like the compressor, condenser fan, evaporator fan, and more, activating them to increase cooling when necessary and deactivating them as the temperature normalizes. Additionally, a defrost thermostat, which is a part of this kit, prevents the evaporator coils from overheating during defrost cycles by acting as an on/off switch in response to temperature changes measured at the evaporator. Symptoms that might indicate the need for this thermostat replacement include inconsistent temperatures in the refrigerator compartments, an overactive or non-functional compressor, or an inability to enter defrost cycles properly. Before purchasing, kindly confirm your refrigerator's model number to ensure compatibility with this thermostat (12001937).
