Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the unit before working on the door lock or control board.
Step-by-step checks:
- Verify correct part: Ensure the door lock assembly is the correct Whirlpool part number for the model.
- Test lock coils: Measure resistance of lock/unlock coils and compare to spec. Replace if out of range.
- Inspect harness: Look for shorts to chassis or between wires.
When to replace: Replace a defective door lock. If the lock and wiring are good but F34 persists, the main control board’s lock driver circuit is likely faulty.
