Re: Advice please Beko CDA543FW-2
the fridge sensor on this model is attached to the evaporator before the foam insulation is applied. It is not available as a spare part but I have heard some engineers have managed to find alternatives. To change it a hole would have to be dug in the right place in the insulation being careful not to damage the soft aluminium pipes. then the new part foamed back in to reseal it
not a job for the amateur in fact I would not even want to do it myself
