DE47-20034A Whirlpool Microwave Thermostat

Microwave Thermostat

Whirlpool offers a range of products under brands such as Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. They also manufacture items for Sears-Kenmore and Ikea. This high-limit thermostat is designed for various microwave models. Its function is to break the circuit when the internal temperature exceeds a certain level, preventing safety hazards. If this thermostat fails or gets damaged, your microwave will stop working.

It's important not to confuse this component with a thermal fuse, which is a single-use item. The high-limit thermostat resets once the temperature drops below the operating level. However, if your microwave frequently shuts off, the thermostat may be defective or the manufacturer might recommend replacing it after it has been triggered. Immediate replacement is necessary to ensure safe operation. Additionally, inspect your microwave for other potential issues that could cause overheating.

To replace the high-limit thermostat, you'll need a flathead or Philips-head screwdriver. Start by unplugging the microwave and removing the side or top cover to access the electronics. Refer to your user manual to locate the thermostat within the main panel assembly. Disconnect it from the wire harnesses, possibly using pliers. Check for visible burn damage on the thermostat and other components. You can also use a multimeter to test for continuity and determine if the thermostat is defective. After installing the new thermostat, reassemble the microwave, and it should function safely.
