Safety: No internal electrical work is usually required for this symptom.

• Check door closure: Ensure nothing is obstructing the door and that the gasket seals all around.
• Allow recovery time: After loading warm bottles, allow several hours for the temperature to stabilize.
• Verify ventilation: Confirm that the wine cooler has the recommended clearance from walls and cabinets.
• Test door switch: If the alarm continues with the door closed, the door switch may be faulty and should be tested and replaced if necessary.
