Refrigerator runs constantly and is too cold; food freezing in the fresh food compartment.

Safety first: Unplug the appliance before accessing sensors or control boards.

Step-by-step:

• Verify settings: Ensure the temperature is not set too low or SuperCool mode left on.
• Check sensor placement: Locate the refrigerator sensor and confirm it is correctly clipped to its mounting point and not touching a cold air outlet directly.
• Inspect damper: Access the air damper and ensure it closes properly when the refrigerator reaches set temperature.
• Replace faulty parts: If the sensor reads incorrectly (tested with a multimeter) or the damper is stuck open, replace the corresponding Liebherr sensor or damper assembly.
