Check Door Safety Switch

What happens here

Locate the door safety switch, which is usually mounted within the dryer door opening and is often activated by a small plastic tab on the dryer door itself. For easier and more accurate testing, it is recommended to carefully remove the switch from its housing. Always ensure the dryer is unplugged before handling this component. Set your multimeter to the continuity setting. Touch the multimeter probes to the two terminals of the door safety switch. This switch typically operates similarly to the start switch: it should only beep (indicating continuity) when its internal button or plunger is pressed (simulating the dryer door being closed). If it does not beep when pressed, or if it beeps when released, the switch is faulty. The video demonstrates a specific issue where the switch's casing was not fully closed, causing intermittent operation; re-snapping the casing back together resolved the problem.

Goal: Confirm the door safety switch operates correctly
