I was looking to repair a Beko CDA539FS-2 fridge freezer I had read that the two PCB boards could be the problem and had replaced them , to no avail. I hadn't thought of the Thermistor/Sensor until I read your article on it. https://www.ukwhitegoods.co.uk/help/fix-it-yourself/specific-faults/4336-beko-electronic-fridge-freezer-sensors. It was a great fix and thanks for the information on your website. I bought the replacement thermistor sensor and the fridge freezer is working normally now. I did need to modify the original Sensor holder the replacement sensor was a tad too big. Its a pity BEKO were not more forthcoming with the information about a replacement sensor and maybe they could have made the part more accessible in their design. Keep up the good work and I am glad to say that one unit at least is saved from the skip . I am sure that more units could be recycled for at least a few more years rather than a early demise. I will certainly use UK Whitegoods in future. Only down side is that they don't deliver to Southern Ireland due to Brexit .
