Beeping alarm with no visible error code, often when door appears closed

Safety: No internal electrical work is required initially.

• Confirm door seal: Push firmly on the door to ensure it latches and seals all around.
• Check for obstructions: Rearrange bottles and shelves so nothing contacts the door.
• Monitor temperature: If the interior is warm, allow time for cooling and check for ventilation issues.
• Inspect door switch: If the alarm persists with a cold cabinet and closed door, test and replace the door switch or reed sensor as needed.
