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.

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.

Dryer won't start

Separate 'dead' (no display) from 'display OK but no start'. Common causes are supply, door switch, thermal fuse (on designs where it is in the motor/control circuit), start switch, belt switch and the drive motor.
