What RE means (liebherr re error)
A liebherr re error points to a compressor or refrigeration-circuit fault on a Liebherr refrigerator. The control flags “RE” when the cooling circuit is not performing as expected — the compressor may not be starting, running, or pumping correctly, so the unit cannot make cold.
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 “RE”
- No cooling at all, or steadily warming compartments
- Clicking from the compressor relay without a steady run
- The unit is silent where the compressor should be running
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.
- Compressor start fault — the relay or inverter cannot start it
- Sealed-system issue — a refrigerant or compressor problem
- Electrical supply fault — voltage out of range
- Control fault — the board cannot drive the compressor
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.
- Confirm the unit has stable power on a correctly rated circuit.
- Power the unit off for several minutes, then restore to clear a transient.
- Move perishable food to a working cooler if cooling has stopped.
- Because RE is a cooling-circuit fault, arrange service rather than continuing to run the unit.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the compressor, compressor relay/inverter, sealed system, and control board. 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
RE almost always needs a technician to test the compressor, relay/inverter, and sealed system and carry out the repair. 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. Where stored food, wine, or temperature-critical contents are at risk, treat a sustained out-of-range condition as a reason to act quickly rather than wait.
