How to Fix / Troubleshooting

Safety first: Unplug the appliance before working inside the cabinet.

Steps:

  • 1. Identify affected zone: Confirm that E1 corresponds to the upper zone on your specific model (check user manual if available).
  • 2. Locate upper sensor: Find the small sensor cover or probe on the rear or side wall of the upper compartment.
  • 3. Inspect and test: Remove the cover, check for damage, and measure sensor resistance. Compare with the lower zone sensor if identical.
  • 4. Replace sensor: Install a new Liebherr upper-zone NTC sensor, routing the cable along the original path and securing it away from shelves.
  • 5. Reassemble and test: Restore power and verify that E1 clears and the upper zone stabilizes at the set temperature.
