This is a high limit thermostat designed for use within various models of microwaves. The purpose of a high limit thermostat is to open the circuit of the appliance when the internal temperature reaches a certain threshold, to avoid becoming a safety hazard. If this thermostat fails or is damaged, it will cause your microwave to stop operating entirely. This is not to be confused with a thermal fuse, which is a one-time use component, whereas this high-limit thermostat resets once it drops back below operating temperatures. But if your microwave has repeatedly shut off, it is defective, or if the manufacturer recommends you replace it after it is triggered, it needs to be replaced immediately for safe operation. Consider inspecting your microwave for other component damage or factors that could lead to your microwave overheating, because that is what is causing this thermostat to be triggered. Replacing the high-limit thermostat will require a flathead and/or Philips-head screwdriver to remove the cover for the electronics of the microwave. First, you will want to unplug your microwave from the wall outlet and use your screwdriver to remove the side/top cover to give you access within it. Using your user manual, locate the thermostat within the main panel assembly and disconnect it from the wire harnesses, which may require a set of pliers. Here you can inspect it and any other components for visible burn damage. You can also test this thermostat for continuity with a multimeter, to see whether it is burnt out or perhaps defective. Install the new thermostat in place and reassemble your microwave, and you can now microwave safely.
