Common Symptoms

Dryer will not turn on at all
No response when pressing start button
Dryer hums but does not spin
Interior light works but dryer won’t run
Dryer stopped working suddenly

Most Common Causes

Bad door switch – dryer will not start if it thinks the door is open.
Faulty start switch – prevents the motor from engaging.
Blown thermal fuse – can completely shut down the dryer.
Drive motor failure – motor may hum but not turn.
Power supply issue – breaker or outlet problem.

Most Common Fix: Replace the Door Switch

If your dryer does nothing when you press start, the door switch is one of the most common failures. This part tells the dryer the door is closed, and if it fails, the dryer will not run at all.
