How to Fix / Troubleshooting

Safety: Unplug the unit before moving sensors or opening any panels.

Usage pattern: Reduce door openings and avoid placing hot items inside. Allow bottles to cool to room temperature before loading them into the cooler.
Check sensor placement: Ensure the cabinet sensor is not directly in the airflow of the evaporator or too close to the door. Reposition it to the original factory location if it has been moved.
Replace sensor: If readings are erratic, install a new Montpellier-compatible NTC sensor.
