Possible Causes

How to Fix / Troubleshooting

Safety first: Unplug the appliance before accessing sensors or internal covers.

Step-by-step:

  • Check settings: Verify that the BioFresh or humidity control is set according to the user manual for the type of food stored.
  • Sensor and flap: Remove the drawer and inspect the rear wall for the sensor and airflow flap. Ensure the flap moves freely and is not blocked by packaging.
  • Temperature check: Place a thermometer in the drawer and compare actual temperature to the setpoint. If significantly lower, the sensor may be faulty.
  • Replace sensor: Install a new Liebherr BioFresh NTC sensor if misreading is confirmed.
