Like I said in my first reply, I unplugged the microwave from the outlet on Sept. 15 and plugged it back in on Sept. 19. I didn't have any problems with it all weekend. It worked every time I used it. Yesterday (Sept 22) I unplugged it again before leaving for home. Today I went back to the campground because I forgot some things. I plugged the microwave back in. The microwave is NOT working again. Maybe I should have left it plugged in. The reason I unplugged it yesterday was because since I'm having trouble with it, I didn't want to leave it plugged in and it shorting out and catching on fire. A new microwave it a lot cheaper than a new camper.
