thermal fuse

A thermal cutoff (thermal fuse) works with the high-limit thermostat to cut power to the dryer's heating element if temperatures rise to unsafe levels. This shuts down the heating circuit, prevents overheating and fire risk, and protects the dryer’s internal components.

A typical dryer thermal cutoff kit includes two primary components: a thermal cutoff fuse and a high-limit thermostat.

By cutting power to the heating element when temperatures become unsafe, the thermal cutoff prevents overheating that can damage heating components and wiring. Preventing excessive heat reduces wear and the risk of serious failures, which helps extend the appliance’s service life.

Kits include a thermal cutoff fuse and a high-limit thermostat. The components are metal and described as made from materials intended to withstand high temperatures.

The kit restores safety functions that shut off the heating element at unsafe temperatures, preventing overheating and protecting internal components.

A dryer thermal cutoff cuts power to the heating element when temperatures become unsafe, stopping overheating and protecting the appliance from heat-related damage.
