Notice details
Freezers rely on steady airflow across the heat-rejection path. Dust near grilles, cabinetry too tight to spec, or nearby appliances dumping heat can all contribute to codes or alarms that look “electronic” but stem from environment first.
Liebherr Appliance Repair publishes this notice for awareness only. Confirm any official manufacturer service bulletin against your serial on Liebherr’s resources.
What to do: Clean accessible grilles per the manual, confirm listed clearances, then contact Liebherr Appliance Repair at the phone number on this site if run times stay long or error codes return.
