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.

Dryer stops early / clothes still damp

An auto cycle that ends early is usually the moisture sensor reading dry (residue, unlevel, small load). A dryer that stops mid-cycle and restarts later suggests motor overheating or a heat-related shutoff.

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.
