First, I waste $65 by calling some "REPAIR" service. They showed at home and charge me that just to tell me Second, I researched on the web and ordered a part, which was not the issue. I waste abnother $72 Third, I found Part-Select and got the right answer: the Diode was the problem. Ordered the part form Part-Select and it FIxed it !!!
Note: I did not buy a new microwave because this one is mounted on the wall and it will cost me +$800 just the lowest price.
Used the trouble shooting guide and wire diagram found inside the microwave (thanks GE). Found the HV capacitor and diode had shorted. Replaced the capacitor and diode........works like new.
