How do I test a dryer door switch?

To test a dryer door switch, first unplug the appliance. Disconnect the wires from the switch and use a multimeter set to continuity mode. The switch should show continuity when the plunger is pressed and no continuity when the plunger is released, indicating it's functioning correctly.

Can a dryer run with a bad door switch?

Typically, a dryer will not run with a faulty door switch. This prevents the drum from spinning or heating while exposed.

Is it safe to bypass a dryer door switch?

Bypassing a dryer door switch is strongly discouraged and unsafe. It disables a critical safety feature designed to prevent the dryer from operating with the door open. This creates a significant risk of injury, especially to children or pets, and could potentially lead to fire hazards or damage to the appliance.
