How to replace a dryer door switch

The step-by-step dryer repair guide explains how to replace a dryer door switch. The door switch sends a signal to the electronic control board to stop the dryer when you open the door. If the door switch fails, the dryer won't start when the door is closed. To quickly test the door switch, open the dryer door and press the door switch lever. If the dryer drum light stays on, the door switch is faulty. Replace the door switch with the manufacturer-approved dryer part.

The video below shows a gas dryer, but the repair is the same. Use these steps to replace the door switch in Kenmore, Whirlpool, Maytag, Amana, Roper, Crosley and Estate dryers with a lint screen housing located in the top dryer panel.
