Customer Questions and Answers for Door Switch (Dryer) by Whirlpool

The door switch detects whether the dryer door is open or closed, enabling the motor and heater only when it's safe. Replacing a failed switch restores proper start/stop control and drum light behavior.

• Senses door position and completes or interrupts the dryer's run/heat circuits
• Shuts the dryer off when the door opens for safety
• Common symptoms: dryer won't start with the door closed; doesn't stop when door opens; drum light stays on or won't turn on
• Intermittent operation when the door is moved or pressed

• Disconnect power before servicing; allow components to cool
• Access the switch from the door opening or front panel; remove screws or release locking tabs
• Note wire positions and transfer them one at a time to the new switch
• Verify operation before reassembly: dryer should not run with the door open; drum light should respond
