Re: Liebherr IKB3660 fridge fault

Is it the control board or is there a less obvious cause?

I have removed and tested the three temperature sensors. They all show the same response as the spare that I recently purchased, around 420 ohms at freezing, 5k at 25 degrees, and 13k at boiling.

The fan operates when the door is closed.

On re-assembly the fridge display immediately shows the ambient temperature, then next morning it’s the correct temperature of 5 degrees C. With a infra red heat gun I measured the temperature profile as :- top shelf 7 degrees C, middle around 4.7 degrees C, meat and vegetable compartments around 1-2 degrees C.

There was a lot of solid ice buildup behind the rear cover. This seems to happen quite quickly, within two-three weeks.

Any ideas?

Is there a test I can make to confirm the board is faulty?

Thanks
