My liebherr freezer isn't displaying a temperature. We found that it was "off". It is now on, but showing 2 flashing lines instead of the temperature.

YOu have to be more clear on the post it dont make much since, also if its brand new should be under warranty

SOURCE: whirlpool fridge freezer (american style)

you have a bad control or bad sensor

SOURCE: we have a liebherr 7082

The two flahing lights are normal if the freezer is warm. It will display temperature when it gets cold. If it doesn't get cold there is another problem.

SOURCE: got an american whirlpool fridge

may be a indication only but on many fridge-freezers, 2 flashing lines ,means power interuption

SOURCE: Fan not working, temperature too cold

You may need a man. Mine was doing the same, The sensor repair kit costs £35 the labour £60, both plus vat, so that was £109.25 in 2009.

Repair men seem thin on the ground and therefore his traveling time may add up. I believe, repair men pay for a course, and then charge like a wounded bull as they are the only ones that can do anything necessary
