Bosch Exclusiv type KGEE31A, after some minute(after power-up) compressor is starts but is cutting down few seconds after and after another few seconds up and so on…
I verify also compressor on direct connected…is ok… temperature is readed ok also. Advice…

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)
