Refrigerator Defrost Thermostat

Whirlpool offers various brands, including Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. They also manufacture products for Sears-Kenmore and Ikea. The Defrost Thermostat Kit, an OEM replacement part, is located at the top of the evaporator in Whirlpool refrigerators. It sends temperature data to the processor, ensuring efficient operation. Identified as L42-30F, this thermostat is vital in the defrost cycle. It closes the heater circuit to initiate defrosting and reopens when the temperature exceeds the set point. Specifically, it opens at 42°F and closes at 30°F, providing controlled heating to melt frost without impacting the refrigerator's contents.

The thermostat includes a male-style spade, bullet connectors, and crimp wire connectors. Its main function is to prevent the evaporator from overheating during defrosting. Installation is straightforward, thanks to a clip on its face. Note that it is recommended to replace the defrost heater when installing the new thermostat.

This part addresses the following issues:
- Freezer not defrosting
- Freezer too cold
- Fridge too warm
- Freezer section too warm
