What Door alarm
actually means.
The door alarm sounds when the freezer door stays open longer than the time set for it, and you can change that time in the settings. After you close the door, the freezer cools harder for a while, so the display can read warmer than the food really is.

What to do when Door alarm shows on the freezerKind of codeMode, not a failure
A setting the freezer was put into, often by accident or by the store it came from, rather than a part that broke: a showroom or demo mode that lights the display while the compressor stays off, a fast freeze left running for days, a Sabbath setting that silences the alarms, a control lock, a door alarm reminding you the door stood open. Nothing has worn out, and the freezer's own buttons or manual put it back.
Usually leads toNo repair
Close the door and check that no drawer, the IceTower tray or a package is holding it open.
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 Door alarm on its freezers. Follow it to the end: the last card says whether this is a visit.
Close the door and check that no drawer, the IceTower tray or a package is holding it open.
Give the freezer time to recover before you judge the temperature on the display.
If the alarm sounds with the door firmly shut, check that the seal sits in its groove, then book a visit.
Cleared?
The freezer is holding its temperature again and no part had to be replaced. If the same code comes back within a few days, or the packages start to soften again, book it as a fresh problem.
What not to do
The door alarm does not mean the door switch or seal has failed if the door really was open. It is also separate from the temperature alarm, which you may see afterward if the door stayed open a long time.
What you may
