E1 and E2 on a Liebherr are temperature-sensor faults. E1 typically flags the refrigerator or upper-zone sensor, while E2 flags the freezer or lower-zone sensor, so the code itself points to the failed component.
The fix is to identify the specific sensor from the code, replace it with a model-specific part, and confirm the zone reports and holds the correct temperature.
Symptom and Error Guide
| Code / Symptom | What It Means | What We Do |
|---|---|---|
E0 | General sensor or electronics warning | Diagnose the flagged sensor, replace, reset |
E1 | Refrigerator or upper-zone sensor fault | Replace the upper-zone sensor |
E2 | Freezer or lower-zone sensor fault | Replace the lower-zone sensor |
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
A zone that drifts before the code appears is an early sign the sensor is failing. Acting on E1 or E2 promptly protects the food or wine the unit is holding.

When to Call a Technician
