Display shows temperature but actual cabinet temperature is significantly different; wines are too warm or too cold.

Safety: Unplug the appliance before accessing sensors or the control board.

Inaccurate temperature display on a De Dietrich wine cooler can mislead storage conditions.

• Use a reference thermometer: Place a calibrated thermometer in the center of the cabinet and compare readings over several hours.
• Inspect sensor mounting: Ensure the sensor is properly clipped to the liner and not insulated by foam or tape.
• Replace suspect sensor: If the sensor is old or has been spliced, replace it with a new, correct NTC sensor.
• Board replacement: If a new sensor does not correct the discrepancy, the control board's ADC or calibration may be faulty and require replacement.
