Misaligned door or hinges, Weak door magnet for reed switch, Faulty door switch, Warped cabinet or door gasket leak

How to Fix / Troubleshooting

Safety: Unplug the unit if you will adjust hinges or access wiring.

Steps to stop false alarms:

  • Verify door closure: Check that the door closes flush with the cabinet on all sides and that no shelves or bottles obstruct closure.
  • Inspect hinges: Tighten hinge screws and adjust if the door has sagged.
  • Check gasket: Ensure the gasket is not twisted or deformed, preventing full closure.
  • Test door switch: Locate the door switch or reed sensor and test with a magnet or by manually actuating it. Replace if it does not reliably change state.
  • Replace magnet (if applicable): If the door magnet is weak or missing, install a new magnet in the original location.
  • Re-test: Restore power and confirm that the beeping stops when the door is properly closed.
