My Frigidaire microwave quit heating although the timer was working - the light came on and the timer clock worked. I had to hold the button that opens the door down slightly to make the heat work. So I could heat stuff by setting the time and standing there with my finger on the door button. I replaced the 3 relay switches in the door panel after reading that it would fix the problem. It did not - and so I called in a repairman (big mistake) and he said it was just the fuse but I think he may have toyed with some wires because now, with a new fuse, it immediately blows the circuit at my breaker box. I am determined to fix this...it lights ups and turns on (beeps) when the power is turned on but when I hit start to test it immediately blows the fuse...Any advice is really, really appreciated.
Thanks, Peggy
