Safety: Unplug the freezer before adjusting or testing the door switch.

Check door closure: Ensure nothing is obstructing the door and that shelves or baskets are not protruding.
Inspect door switch: Press the switch repeatedly and listen for the alarm to stop/start. Replace the door switch if it behaves erratically.
Clean gasket and frame: Dirt can prevent full closure; clean both surfaces.
Reset alarm: Use the alarm reset button if provided. If nuisance alarms persist, the main PCB may need calibration or replacement.

Freezer alarm beeps intermittently but no error code is shown and temperature seems normal.
