Function & Importance

The WP4375079 high limit thermostat plays a critical role in microwave safety. It continuously monitors internal temperatures and automatically shuts off power if unsafe heat levels are detected. This prevents damage to internal components such as the magnetron and wiring, while also reducing the risk of fire or electrical failure. Without a properly functioning thermostat, a microwave may overheat, operate unpredictably, or fail completely.

This component is essential for maintaining safe operation and extending the lifespan of your microwave oven.

Common Symptoms Indicating Replacement

A failing microwave high limit thermostat may cause the following issues:

• Microwave shuts off suddenly during operation

• Unit stops heating but still powers on

• Microwave will not start or runs intermittently

• Overheating or burning smells
