    Hi
    On past experience, it is usually the PCB thats is plugged inhorizontally behind top fascia. P/no – 263781.
    On a rare occasion you may have a faulty compresser 😥

    Thanks Greg, I did guess that.
    I have taking at home PCB to see what’s dead in it.

    After removing condens residual from PCB and resoldered cold contacts it works for three days OK. This morning I found him in alarm condition with 18’C inside both compartments.
    Can any help me with electric diagram & correspondence between temperature=sensor resistance?

    Costumer doesn’t want to pay new one. He wants to try repairing.

    Hi

    I don’t think thats recommended, although you could look for 2 black diodes on that module that look like they have scorched the PCB board below them, and replace them. Before you ask I have no idea what type/ value they are 😀

    Yes they are two 12 Volts Zenner diodes. It looks they are OK. Under them on the oder side is one 16Volts (SOT223 cases) is schoching PCB. I will change that three diodes. But I need electric diagram and value of those three sensors in order to check at home PCB(to simulate fridge enviromment)
