What Power failure alarm
actually means.
Liebherr shows the power failure alarm when the freezing temperature rose because of a power outage. Once power is back, the freezer cools down to its old setting on its own; the message stays so you know to check the food.

What to do when Power failure alarm shows on the freezerKind of codePower and voltage
The freezer saw its supply voltage drop, spike or vanish, and many models log that as a code after an outage or when the power returns. 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 toFreezer 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 asFreezer 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.

Before you book,
in this order.
Each step comes from Liebherr's own guidance for Power failure alarm on its freezers. Follow it to the end: the last card says whether this is a visit.
Touch the display to see the warmest temperature reached during the outage.
If it stayed below 16°F the food can be kept; if it went higher, check each item and do not refreeze anything that fully thawed.
Confirm the message so it clears, and book a visit only if the freezer does not return to its set temperature within a day.
Still there?
It usually turns into freezer diagnostic visit. Book with the code and the model number.
What not to do
The power failure alarm does not mean the freezer is damaged; it is a record of the outage. If the display stays dark after power returns, the appliance is not getting power, which is a different problem.
