Understanding the Problem
The thermal fuse is a one-time safety device that blows when the dryer overheats, cutting power to the dryer or the heating element. If you keep replacing the thermal fuse and it keeps blowing, the root cause of the overheating hasn't been addressed. Common root causes include a clogged exhaust vent, a failed cycling thermostat, a shorted heating element, or a worn felt seal.

Helpful Repair Tip
Replacing the thermal fuse alone will not fix this problem permanently. You must find and fix the root cause: (1) Clean the exhaust vent completely. (2) Test the cycling thermostat. (3) Check the heating element for grounding — if the coil touches the housing, it stays on too long. (4) Check felt seals for heat leaks. Fix the root cause, then replace the fuse.
