Liebherr Combined Unit Code Alarm Symbol: freezer section warmer than set

What Alarm Symbol means

On Liebherr US combined units such as the HCB 1560, the alarm symbol appears together with a flashing temperature readout. It tells you the freezer section is warmer than it should be. Open doors and freshly loaded food are the two situations the unit is built to warn about. The warning stays on and the readout keeps flashing until the cause has been removed, so a flashing display means something needs your attention right now.

Common causes of Alarm Symbol

A freezer drawer or door left open or not fully latched
A large amount of fresh, warm food loaded at one time
Door seals that no longer close tightly
A cooling problem in the unit itself, which a technician has to confirm

✓ One safe check you can try

1. Close every freezer drawer and the door firmly and check that nothing blocks the seal. 2. Note whether you recently added a lot of fresh food; that load alone keeps the flashing going until it freezes through. 3. Wipe the door seals and look for gaps or frost build-up. 4. Wait several hours and see if the flashing stops. If it keeps going, move food you care about to another freezer and call us.

! Why to stop there

The flashing only stops when the real cause is gone, and a technician can tell a loading or door issue from a cooling problem in minutes.
Frozen food that thaws and refreezes loses quality, so a quick answer protects what you have stored.
Opening the unit up yourself risks the sealed refrigeration system and the electrical parts.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Alarm SymbolAlarm Symbol questions

Why is the temperature number flashing on my HCB 1560?

The flashing readout and alarm symbol mean the freezer section is too warm. The display keeps it up until the cause, such as an open drawer or a big load of fresh food, has been dealt with.

Will the alarm clear by itself?

Yes, when the cause is removed. If you closed a drawer or finished loading food, the warning ends once the freezer section is cold again. If it keeps flashing for many hours, the cooling needs a technician.

Is my food safe while the alarm is on?

Check how warm the freezer section got and how long it stayed that way. Food that is still hard with ice crystals is fine to keep. Soft or thawed food should be cooked soon or discarded.
