# Liebherr freezer column: The power failure LED is lit and the freezer display flashes

### This is an indicator, not an error code

If the power failure LED is lit, this means the freezer temperature has risen too high during the last few hours or days due to a power failure. The freezer temperature display flashes at the same time. If you touch the Alarm icon now, the highest temperature registered during the power failure will be displayed.

It is on this page because it is what somebody is actually looking at when they go searching. Most of this maker’s equipment publishes no code at all, and an appliance that flashes at you is still telling you something — it simply is not telling you a number.

This is the one people describe as **liebherr freezer beeping after power outage**, and on this make it is documented rather than broken.

### What to do

- Touch the alarm icon before clearing anything. The appliance will show you the highest temperature the freezer reached while the power was off.
- Use that number to decide about the food rather than guessing. Previously frozen food that has thawed should not be refrozen.
- Then clear it. There is nothing to repair — the indicator existing is the appliance doing its job.

### What the repair is

Conditions like this one end at [Alarm and power-failure diagnosis](https://liebherrmiami.support/services/alarm-and-power-failure-diagnosis/) more often than anywhere else. The figure on that page is a starting point; the exact cost is confirmed after an on-site diagnostic and agreed in writing before anything is opened.
