There was a power cut in our street a couple of weeks ago and ever since then the clock/timer on our oven randomly resets to the flashing 12:00 accompanied by a nasty sounding buzz noise. How do I fix this problem? Is it actually the fault of the clock or could there be a problem with the cookers mains switch/fuse?
you have answered your own question really.could be either of the above causing the problem.Nasty buzz tends to point to timer/clock issue but without taking the plunge and replacing it its hard to say!!
