What — on display means (liebherr dashes display)
A liebherr dashes display condition — a “–” shown where a temperature should be — means the control on a Liebherr refrigerator cannot present a valid temperature reading. It can indicate a sensor the control cannot read, or that the unit is in demonstration/showroom mode and is not actually cooling.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your Liebherr Refrigerator. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- The display shows “–” instead of a number
- No temperature value can be set or read
- The unit may not be cooling (demo mode)
- The condition may follow first power-up or a reset
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level fix from a problem that needs trained service and the correct Liebherr parts.
- Demonstration mode active — showroom mode disables cooling and the display
- Sensor unreadable — a thermistor the control cannot interpret
- Initialization state — the unit is still starting up
- Control fault — the board cannot resolve a valid reading
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where the sealed refrigeration system or live electrical parts are involved, and hand the rest to a qualified technician.
- Check the owner guide for the demo/showroom mode exit sequence and perform it.
- Power the unit off for a few minutes, then restore and allow it to initialize.
- Confirm the unit is actually cooling after the dashes clear.
- If “–” stays and the unit is not in demo mode, book service.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the temperature sensor, demo/showroom mode, control board, and display. The correct part for your Liebherr Refrigerator is matched from the model and serial number, and genuine Liebherr components are fitted rather than generic substitutes so that cooling performance, energy efficiency, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
If the dashes persist with demo mode off, a technician should test the sensors and control board. When the fix calls for trained service, book a visit through our scheduling page and our certified technicians will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your Liebherr Refrigerator. Keep the condenser and ventilation grille clean, avoid overloading or blocking air outlets, check the door gasket for a clean seal, and follow the Liebherr maintenance guidance for your model. Because this unit uses electronic temperature management, protect it with a stable, correctly rated power supply and have any built-in installation done to Liebherr specification so the control never sees an out-of-range condition. If a code or alarm appears, note exactly what was shown before you reset the unit — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily.
