# Liebherr beeping after a power outage

### The fastest diagnosis is what the appliance is telling you

Touch the alarm icon. The appliance will show you the highest temperature the freezer reached while the power was off — the single number that decides what is safe to keep, and it is free.

### Why this deserves its own page in Miami

Because outages here are seasonal and predictable, and every one of them produces the same round of calls to every appliance company in the county. The answer is almost always the same: the appliance noticed, recorded and reported. Knowing that in advance turns an emergency into a five-minute check.

The power-failure indicator, working

Documented. The light means the freezer got too warm during the outage, and the display flashes with it. There is nothing to repair.

Two dashes while it comes back down

The freezer display only shows below-freezing temperatures. After an outage it takes three to five hours to get there.

It genuinely did not restart

Rare and real. Check the breaker before anything else — the maker's own troubleshooting starts there.

Read the recorded temperature first

Touch the alarm icon before clearing anything.

Check the breaker properly

Off and fully back on. A breaker can look set and have dropped.

Give it five hours before judging

From an outage, a freezer needs three to five to show a number again.

The appliance recorded what happened

### Do I have to throw the food away?

That is what the recorded temperature is for. Read it before you clear the alarm — the appliance kept the number precisely so that you would not have to guess. Anything that thawed and was refrozen is a separate question, and the maker is clear that previously frozen food which has thawed should not be refrozen.

### The light is on but everything is frozen.

Then it got warm at some point and recovered. The light is a record rather than a live reading. Clear it, and it stays clear unless it happens again.
