What's Happening

The door lock mechanism isn't engaging properly. The dryer won't start because it can't confirm the door is securely closed. Something may be caught in the seal or the lock mechanism is faulty.

How to Fix It

Check for items caught in the door seal. Close the door firmly until you hear it click. If the latch appears fine but the error persists, reset power at the breaker for 30 seconds. The door lock mechanism or its sensor may need replacement.
