How do I test a dryer door switch?

To test a dryer door switch, first unplug the appliance. Remove the switch and use a multimeter set to continuity mode. Touch the probes to the switch terminals. The multimeter should show continuity when the switch plunger is depressed (door closed position) and no continuity when it is released (door open position).

Can a dryer run with a bad door switch?

If a door switch fails in the closed position, the dryer might operate even with the door open, creating a significant safety hazard. If it fails in the open position, the dryer will typically not start at all, as it will not detect that the door is closed.

Is it safe to bypass a dryer door switch?

Bypassing a dryer door switch is strongly discouraged. This component is a critical safety feature designed to prevent the dryer from operating when the door is open, reducing the risk of injury or fire. Always replace a faulty switch rather than bypassing it.
