What Not Freezing means (liebherr freezer not freezing)
A liebherr freezer not freezing problem is reported as a symptom rather than a single code on a Liebherr freezer, though a HI or AL02 alarm may appear with it. The unit is powered and may run, but the compartment never reaches a freezing temperature.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your Liebherr Freezer. 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.
- Food fails to freeze or partly thaws
- The interior is cool but not cold
- The compressor runs constantly or not at all
- A high-temperature alarm may accompany it
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.
- Sealed-system issue — a refrigerant or compressor problem
- Evaporator fan fault — cold air is not circulated
- Defrost fault — frost chokes the evaporator
- Door seal leak — warm air infiltrates the cabinet
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 setting is correct and the unit is not in demo mode.
- Make sure the door seals fully and the gasket is clean and ice-free.
- Clean the condenser and clear the ventilation grille.
- If the freezer still will not freeze, move food and book service.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the sealed system, evaporator fan, defrost system, door seal, and control board. The correct part for your Liebherr Freezer 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 a freezer will not freeze after airflow and door checks, a technician should test the fan, defrost system, and sealed system. 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 Freezer. 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. Note when the symptom first appeared and what changed around the same time — a recent load, a warm room, a power event, or a relocation — because that detail often points a technician straight to the cause and keeps the repair simple. 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.
