Whirlpool Thermostat Kit 12001937 OEM Part

Whirlpool, a leading manufacturer, offers a range of brands such as Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral, and also produces appliances for Sears-Kenmore and Ikea. The Defrost Thermostat Kit, designed as an OEM replacement part, is situated atop the evaporator in Whirlpool refrigerators. Its role is to relay temperature data to the processor, promoting optimal performance. Known by the identifier L42-30F, this thermostat plays a crucial role in managing the defrost cycle. It activates the heater circuit to start defrosting and deactivates it when the temperature surpasses a predetermined threshold. Specifically, it opens at 42°F and closes at 30°F, ensuring that frost is removed effectively without compromising the refrigerator's contents.

Equipped with a male-style spade, bullet connectors, and crimp wire connectors, the thermostat is designed to prevent overheating of the evaporator during the defrost process. Installation is uncomplicated due to its front clip feature. It is advisable to replace the defrost heater concurrently with the thermostat installation.

This component effectively resolves the following challenges:
- Freezer not defrosting
- Excessive cold in the freezer
- Insufficient cooling in the fridge
- Warm temperatures in the freezer compartment
