    Obviously that didn’t do the trick and about a week after posting the fridge was iced up again. I’ve stuck a timer on it, so it switches off a few hours each night and it’s been limping along like that. On the plus side, the freezer’s still working perfectly with the new fan, so I’m very happy about that.
    Not being one to give up easily, I’m now wondering what to change next. The diagnostic test (pressing both top buttons for a few seconds) shows no errors. When I tested resistance of the defrost and drain heaters, both were correct. The thermal fuse and sensor tested ok too. If the fuse was at fault, or either heater was open circuit, I’d have expected a fault code to show. Actually, maybe not the heaters as they’re both connected to same plug.
    In any case, I’m wondering which of the above to change next – or is there something else to try?
    On fridge side, I’ve changed the evaporator cover to new type, the water bottle, the door seal and the fan (which is now frosted up again judging from the noise it’s making).
    Is there a way of testing that the heaters are getting a feed? I’m wondering if it’s a control problem.
    If not, can anyone point me in the direction a reasonably priced kit with all those components, so I can change them all out in one go?
    Thanks!

    Hello, Chally
    No, I’m afraid I decided to stop throwing good money after bad and shelled out for a new Fridge Freezer.
    Silly to have chucked out what was probably a perfectly good fridge if only I could have diagnosed what needed replacing. Have been stung for call-outs for domestic appliances when they got beyond me before and ended up having to buy a new (microwave and washing machine) anyway so thought I’d cut out the expensive middle man this time.
    Good luck with your one!
