The outlet, the circuit, a GFCI in a garage or basement and an extension cord are checked before anything inside the freezer. If there is a burning smell or the breaker keeps tripping, switch the breaker off from a dry panel and leave it off until the visit. ### Usually leads to Freezer diagnostic visit A visit that starts with the food and the room the freezer stands in, then works through the seal, the airflow, the defrost and the compressor until one part is named. ### Shows up as Freezer Error Code A freezer error code appears on the display: letters and digits, a flashing temperature, or a warning symbol, sometimes with an alarm and sometimes with the freezer still running. ### Make Liebherr Liebherr freezers repaired in the home when the cabinet warms, the alarm sounds or frost builds up. ### Source Liebherr operating instructions, SF5291 freestanding freezer (OI SFNsth 529i) SF5291, SIF5181 and UF3651 Touch & Swipe freezers (Power failure alarm) and Monolith columns (Power Alarm).

Touch the display to see the warmest temperature reached during the outage. If it comes back, it needs a visit. ### Do I need to reset my Liebherr freezer after a power failure alarm? No. It returns to the temperature you set without any input. You only confirm the message so it disappears. ### How long is food safe after a Liebherr power failure alarm? Go by the warmest temperature the display shows. Liebherr says food that stayed below 16°F can still be eaten; above that, check it item by item. ### Why didn’t my Liebherr show a power failure alarm after an outage? If SabbathMode was on, Liebherr does not show the message at all, and the appliance goes back to SabbathMode when power returns. Check the food yourself after any outage in that mode. --- **[Read on the site: Liebherr Power failure alarm: the freezer warmed during an outage](https://freezerrepair.center/error-codes/liebherr-power-failure-alarm/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
