Intermittently, but increasingly repeatably, the microwave self-starts when you close the door. No button pushes involved, nothing more than having taken out the already heated food from a previous correctly working cycle. Yes, removing the previously heated food and replacing it with a cold cup of water demonstrates that the magenetron is DEFINITELY working: the water heats during this self-start cycle. Dang ... simply closing the door starts the heating cycle. No sequence of button pushes ... including "CLEAR" ... will stop the cycle. Only opening the door stops it. Then, randomly, it stops after an arbitrary number of door openings/closings. No, there have been no other appliances (including computers, new HD TV, cordless phones, etc.) exhibiting weird symptoms, suggesting that a voltage surge is NOT the problem. Any sugestions?

If electronic control, one of two things come to mind. 1)your toutch pad is defective.replace it. 2)you electronic board has a leaky component.not very likly though. believe it or not, ive seen it start before by itself then i noticed a large quantity of bugs inside the glass which i realised triggered the microwave 0ff.

Sounds like an intermittent door switch or a loose door switch mount. Very common.

Update: occasionally, (less than 20% of the time), but randomly ... the magnetron does not kick on. I.e., the platform turns, the fan runs, the light lights, and it sounds like the unit is in a cook cycle, but no heating occurs. Given the low frequency of no magenetron action, odds are the next time you open the door and it self-starts, it WILL heat (and often does).
No bugs inside the glass; the "bugs" are in the "unit operation" only.
OK, this sucker is computer controlled, right? So how does one do a "reset" and a subsequent "cold start"? I've tried flipping the breaker controlling the microwave "off" and after a few minutes flipping it "on" again. "No joy"; it still behaves the same way: irratic.
Any suggestions on the best way to get GE's attention to what is (to me at least) obviously a safety issue? The unit is only 8 years old, hardly geriatric, and was near the top of the line when purchased. Or, are we better off writing off GE in the future and going with another brand. If so, which one?

'Clear button does not stop it. Otherwise it can be programmed and heats as normal
