Wine cooler interior is too cold and bottles may partially freeze even at a moderate set temperature.

Safety: Unplug the unit before adjusting sensor placement or accessing the control board.

Overcooling in a De Dietrich wine cooler is usually due to incorrect temperature sensing.

• Check setpoint: Confirm the displayed set temperature is appropriate for wine storage (typically 10–14°C for reds, 6–10°C for whites).
• Verify with a thermometer: Place an accurate thermometer in the middle of the cabinet and compare to the display. Large differences indicate a sensing issue.
• Inspect sensor placement: Ensure the cabinet NTC sensor is firmly clipped to the liner and not hanging in free air or touching the evaporator directly.
• Replace suspect sensor: If the sensor is correctly placed but readings are inaccurate, replace it with a genuine De Dietrich NTC sensor.
• Board calibration: If a new sensor does not resolve the issue, the control board may have an internal calibration fault and should be replaced.
