TL;DR
The dryer thermal cutoff is a one-time safety fuse mounted on the heater housing that permanently opens the heating circuit when temperatures climb past its rating, commonly around 250 to 350 degrees Fahrenheit. It exists to prevent fires, and once blown it never resets — the part must be replaced.
What it means
The dryer thermal cutoff is a one-time safety fuse mounted on the heater housing that permanently opens the heating circuit when temperatures climb past its rating, commonly around 250 to 350 degrees Fahrenheit. It exists to prevent fires, and once blown it never resets — the part must be replaced. Because overheating almost always traces to a lint-blocked vent or failed cycling thermostat, a competent repair replaces the cutoff and fixes the airflow cause in the same visit.
