Possible Causes

How to Fix / Troubleshooting
Safety: Unplug the appliance before moving sensors or accessing the control board.
Short cycling can reduce compressor life in De Dietrich wine coolers.
- Check ambient conditions: Extremely hot rooms can cause rapid cycling; improve ventilation around the unit.
- Inspect sensor placement: Ensure the cabinet sensor is not directly in the cold air stream from the evaporator, which can cause rapid temperature swings at the sensor.
- Clean condenser and check fan: Overheating can trigger protective shutdowns; ensure good airflow and fan operation.
- Board replacement: If mechanical and sensor issues are ruled out, the control board's logic may be faulty and require replacement.
