Alarm beeps intermittently but no error code is shown; temperature appears normal

Safety: No internal electrical work is required for basic checks.

Steps:

• Confirm door closure: Push firmly on the door after closing to ensure it latches and does not spring back.
• Inspect door switch: Check the door switch or magnetic sensor alignment. Adjust the switch position or magnet so they align correctly when the door is closed.
• Check gasket: Replace the door gasket if it is deformed and preventing full closure.
• Alarm settings: Some models allow disabling or adjusting the door alarm delay; consult the manual and adjust if necessary.

Note: Persistent false alarms with a properly closing door may indicate a faulty door switch or control board input.
