Liebherr Sensor Reading Out of Range

Display shows dashes or blank temperature instead of a value, but no specific error code.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Disconnected or failed temperature sensor, Broken harness between sensor and PCB, Control board input fault

Safety first: Unplug the freezer before accessing sensors or electronics.

Steps:

Locate relevant sensor: Identify which compartment's temperature is missing and locate its NTC sensor.
Check connection: Ensure the sensor plug is firmly connected at both ends.
Test sensor: Measure resistance at room temperature; an open or shorted sensor will cause the display to show dashes.

Remedy: Replace the faulty sensor. If a new sensor does not restore the reading, the main control board input channel may be defective.
