Spent a lot of time on the internet, to discover that the problem was either the vent door motor or the position switch. Replaced both. Repair shop wanted to look at it for $250 and RV insurance had a $250 deductible. The motor appears to work, it was probably the switch, no way to test either item. The microwave now works as it should, all for $42 w/ shipping. Easy enough to repair. Getting it out of RV was more of a problem, but again easy if you understood how. Remove the top mounting screws, bolts, or whatever and then take out the two long diagonal screws from the grease filter areas to the upper rear. They mount into the wall plate that is the size of the back of the microwave. Place a microwave size sturdy cardboard box on stove to hold weight of microwave as it releases from the back plate.
