Whirlpool Microwave Fuse Or Sensor

This is a fixed high limit thermostat that monitors the internal temperature of the microwave and shuts off the unit if it overheats. It acts as a safety device to prevent damage to components and reduce fire risk. Replace this thermostat if the microwave shuts off unexpectedly during use, fails to start, or if continuity testing shows the thermostat is open.

This thermostat monitors the temperature of the magnetron in the microwave and shuts off power if overheating is detected. It is mounted directly on or near the magnetron tube. Replace this thermostat if the microwave shuts off unexpectedly during use, fails to heat food, or if continuity testing shows the thermostat is open.

If your microwave overheats or the vent fan runs constantly, this fixed thermostat may need replacement. Controls heating and safety shutoff.

This fixed thermostat monitors and limits temperature to protect the appliance's system and components. It's a simple, non-adjustable sensor/limit switch used where a set cutoff temperature is required for safe operation. What it does:

• Opens or cuts power when the monitored temperature reaches its fixed limit to prevent overheating
• Helps stop continuous heating cycles caused by a failed control or sensor
• Commonly used as a safety cutoff in temperature-control circuits
• Can resolve symptoms like persistent overheating, failure to stop heating, or temperature-related shutdowns

• One fixed thermostat (single unit)

• Disconnect power before inspecting or replacing the thermostat to avoid shock or damage
• Handle gently; avoid bending terminals or stressing sensing elements

This assembly combines a humidity sensor and thermostat used in over-the-range microwaves to detect moisture and temperature levels during cooking. The humidity sensor enables auto-cook and auto-reheat features by sensing steam released from food, while the thermostat monitors internal temperature for safety. Replace this part if your microwave no longer accurately auto-cooks or auto-reheats food, runs too long or shuts off too early, or if you get error codes related to sensor functions.

Prevents magnetron overheating in your microwave. This cavity over-temperature thermostat shuts off power when temperatures exceed safe limits.
