Washer-dryer combo shows F29 and will not unlock the door at the end of the cycle.

Safety first: Unplug the unit. If water is present in the drum, manually drain it before attempting to open the door.

Step-by-step checks:

• 1. Wait for cool-down: Some models delay unlocking if water is too hot. Wait 5–10 minutes and try again.
• 2. Manual release: Access the door lock from the front by removing the lower panel or pulling back the door gasket. Many Maytag locks have a manual release tab you can pull to open the door.
• 3. Inspect lock: Once accessible, check the lock for physical damage or signs of overheating.
• 4. Test lock coil: With the lock disconnected, measure resistance of the lock/unlock coils. Replace the lock if coils are open or shorted.
• 5. Wiring and control: Inspect the harness to the lock. If wiring is intact and the new lock still does not unlock, the control board may be faulty.
