Door alarm beeping even when doors appear closed.

Safety first: No high-voltage work is required for basic checks; unplug if replacing switches.

• Check door closure: Ensure no food items or shelves are preventing the door from closing fully.
• Inspect gasket: Look for warped or damaged gaskets that keep the door slightly open. Replace if necessary.
• Test door switch: Press the switch manually; the interior light should turn off and the alarm should stop. If not, replace the door switch.
• Adjust door alignment: Level the refrigerator and adjust hinges so the door lines up properly with the cabinet and contacts the switch.
• Control reset: If the alarm persists after mechanical fixes, reset the control by unplugging for 5 minutes. Persistent false alarms may indicate a control board issue.
