Liebherr Larder Fridge, control issue

[PeterAtchison]

I have a liebherr 600mm larder fridge Model No 7082072-00 which seems to have an electronic control unit rather than conventional thermostat (From earlier forums) Unlike the previous poster, mine will not switch ON. If I press the "super cool" button it works fine for 6 hours (then switches off, on the timer I guess) The electronic display is showing Green and 5 degrees or 3 degrees when it evidently is not! Could this be a sensor issue and if so are they available and easily replacable?

Thanks

on a thermostat one, when u super cool or like super freeze, it by passes the stat to run the compressor, on the h/ps the electronic ones are the same, so i would say power board or a thermistor , u want the resistance values really to check them.
