Door alarm sounds even though the door appears closed; alarm may stop if door is pressed firmly.

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

• Check door alignment: Verify the door is level and flush with the cabinet. Adjust hinges to correct sagging.
• Inspect gasket: Look for gaps where the gasket does not contact the cabinet. Replace if deformed or torn.
• Test door switch: Manually operate the switch and see if the alarm stops. Replace the switch if intermittent.

Persistent false alarms after mechanical corrections may indicate a control board input fault.
