Liebherr Temperature Alarm Going Off

Error Guide · 2026-06-11

Undercounter ice maker diagnostic visit in Southampton

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.

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.
