Understanding the Dryer Door Switch
What Is a Dryer Door Switch?
The dryer door switch is a safety device that prevents the dryer from operating when the door is open. It acts as a gatekeeper, ensuring that the dryer only runs when the door is securely closed. The switch is typically a small, button-like component located near the door frame that activates a circuit when pressed.
Why Does the Door Switch Fail?
Over time, the door switch can fail due to:
- Wear and tear from frequent use
- Physical damage or cracks
- Dirt, debris, or corrosion affecting the contacts
- Electrical surges or power fluctuations
A faulty door switch can manifest in several ways, such as the dryer not starting, the door light remaining on or off, or error messages appearing on digital displays.
