Hi, got a zanussi zx99/5w, its 6 years old and recently temp warning light kept flashing and beeping. I hoovered the coils (covered in pet hair!) at the front which did help for a while, then started to notice bad smell in fridge so cleaned thoroughly and eventually smell went away but now it has completely stopped working, no warning lights and the green light blinks off every minute or so accompanied by a small click from circuit board in the back, no fans going, not making any noise. I did try defrosting for 24hrs but still nothing, ive taken back panel off and hoovered out, unscrewed bits in the freezer part and removed cover but did not want to remove freezer part at the top. Sorry not very technical! any ideas would be greatly appreciated.
