Safety first: Unplug the refrigerator before adjusting hinges or replacing switches.

Steps:

Check door closure: Ensure doors close fully without bouncing back. Adjust leveling legs to tilt the unit slightly back.
Inspect gaskets and hinges: Look for warped gaskets or sagging doors that prevent full closure.
Test door switch: Manually press the switch; if the alarm stops, the switch is working but the door may not be contacting it properly. If it does not stop, test and replace the switch.
Magnetic systems: For reed switches, verify the door magnet is present and aligned.

Corrective action: Adjust hinges, replace worn gaskets, and replace faulty door switches or magnets as needed to restore proper door detection.

Door alarm beeping even when doors appear closed.
