WB21X10046 General Electric Thermal Fuse

The Microwave Thermal Fuse, also known as the Thermal Cut-Out (TCO) Oven Cavity, is an essential replacement part designed for GE microwave ovens. This part is critical for safety, as it shuts off power to the microwave's oven cavity if the internal temperature surpasses safe levels, thereby mitigating the risk of overheating and potential fire hazards.

Common indicators of a malfunctioning TCO oven cavity include:
- The microwave not heating or ceasing to function
- Display of error codes or warnings concerning thermal issues
- Unusual smells like burning or visible smoke emanating from the appliance

Factors that may lead to TCO oven cavity failure often involve normal wear and tear, exposure to unusually high temperatures, electrical fluctuations, or damage from physical impacts.

This specific GE part is also suitable for use in appliances from Hotpoint, RCA, and select models from Kenmore, enhancing its versatility across different microwave brands.
