Dryer overheating / cabinet too hot

Overheating is a fire risk. Restriction is the usual cause; after that, a cycling thermostat stuck closed, an element grounded to the housing, or a heater relay stuck on can keep heat on.

Electric dryer runs but no heat

Most electric no-heat calls come down to supply voltage (one breaker leg), a blown thermal fuse from a restricted vent, a tripped high-limit, or an open element. Always fix the airflow cause, or the new fuse will blow again.

How to test a high-limit thermostat (dryer and similar heaters)

A high-limit is a normally-closed bimetal switch that opens if the heater area overheats and closes again when it cools. A room-temperature continuity test catches the common "stuck open" failure, but it cannot prove the opening temperature is right.
