I have one too under another name, Hoover, same thing with Candy parts. Worked more or less for first year then failed to cool in both freezer and fridge part. Freezer was +1.4c fridge +14c. After switching off (at mains) and defrosting for two days which it should do by itself but fails to properly, the freezer worked again -20c, but fridge stayed at +12/+14 depending on room temperature.
Eventually decided to examine myself, thermostat in fridge goes through control unit too I think, anyway took cover off evaporator in freezer section only to find that the white wall behind had cracks and had yellowed in one part, whether this happened before it was delivered to me as brand new or a result of the defrost heating element staying on too long/overheating I don't know.
However I noticed that there are no ducts for cold air to be blown into the fridge section, just a small hole for the wires to the heater and thermal switch, neither are there any vents in the fridge section for cold air to be blow in. I have read lots of engineers’ articles going on about these but this model does not have any. Neither Candy/Hoover supply exploded technical diagrams or service manuals for these and so far no engineer I came across seems to mention these fridges as they talk about air circulation from freezer to fridge, not on this model (unless it's going through a polystyrene filled penny sized wire hole away from and behind fan and thru insulation to back wall of fridge).
The back wall off the fridge does get cool and once ice built up on it from time to time before it completed failed. I need to know if there is an separate evaporator of some kind behind the fridge wall, unfortunately with no diagrams for these models available and no engineer mentioning anything about these models fixing DIY in the dark would be a pain, may as well take one to pieces as the rear section is sealed which insulation and no access able parts.
There is a tube from the compressor that goes up into that foam somewhere, one capillary goes to freezer if another goes to mystery evaporator behind the fridge wall I don't know. In any case it seems these particular models have are flawed and with no available official construction information all deliberate to make money from after service, it was good that I kept my old fridge which although small lasted over 40 years and even today saved my food from the failings of modern design.
Oh the model I have is called a Hoover HNC6185A4 with a Candy circuit control board at rear next to the compressor. Maybe it's just a dodgy fridge thermostat/control unit, I would understand that if behind the fridge wall was secondary sealed evaporator, maybe someone out there knows, maybe it is a dark secret or even conspiracy of some kind.
Therefore if a manufacturer does not supply a schematic or make easily available a service manual for their product like they did in the old days its best not to buy their products if at all possible.
