A Liebherr temperature alarm can be simple or serious. A door left ajar or a warm load will trip it temporarily, but a persistent alarm signals a cooling fault such as a failed evaporator fan or a defrost problem.
The fix is to confirm the door and load first, and if the alarm persists, test the evaporator fan and defrost system and replace the failed component.
Symptom and Error Guide
| Code / Symptom | What It Means | What We Do |
|---|---|---|
Brief alarm | Door open or warm load added | Confirm the door and load |
Persistent alarm | Evaporator fan or defrost fault | Test the fan and defrost, replace the part |
Alarm with warm zone | Cooling or sensor fault | Diagnose the cooling circuit |
What We Check
- Temperature alarm sounding on a column or wine cabinet
- E0, E1, or E2 sensor fault on the display
- Refrigerator or wine zone running warm
- Wine cabinet drifting off a set zone temperature
Making sure the door closes fully and not overloading the unit prevent nuisance alarms. A persistent alarm should never be silenced without diagnosing the cooling system.

When to Call a Technician
