TL;DR
A thermal fuse is a one-shot safety device wired into dryers, ovens, and other appliances that permanently opens the circuit when it reaches its rated temperature, unlike a thermostat that resets. In dryers it mounts on the blower housing or heating element and commonly blows because a lint-clogged vent let exhaust temperature climb.
What it means
A thermal fuse is a one-shot safety device wired into dryers, ovens, and other appliances that permanently opens the circuit when it reaches its rated temperature, unlike a thermostat that resets. In dryers it mounts on the blower housing or heating element and commonly blows because a lint-clogged vent let exhaust temperature climb. Replacing the fuse without clearing the vent restriction guarantees a repeat failure, which is why technicians check airflow before closing up.
