Have a GE microwave model JVM6175DF1WW. Over the last week, it's been resetting power randomly (where you have to reset clock), sometimes shutting down all the way. When it shuts down, I unplug/replug and reset clock, if it powers up. Today it shut down and would not turn back on (we could smell something burning this time). I took the top vent off and removed the touch/control pad and disconnected/reconnected all the plugs and put everything back together, and it powered up again. But after starting it up again, it ran for 3 seconds and shut off again.
For this microwave, I've replaced the front touchpad once (about 2 years ago), and the two front door switches just this summer. Not sure if it is worth putting more money into it this time. I may buy a Whirlpool this time.
But if the problem is cheap/easy, I may try once more. Any ideas what to do/check or what the problem might be? I have access to a multimeter, but won't be able to get it until tomorrow.
