Microwave Overheating - Catch on Fire???

Hi All. I'm in a 2004 PleasureWay Excel TS. When I got a new generator (Onan from Cummins), they told me as part of regular maintenance to run a heavy load on it (including the a/c and microwave) for about an hour per month. I did that today for about 15 minutes.

The microwave was extremely hot to the touch. Turned off the microwave and the GenSet. Afraid to use it now. Has anyone had this problem? Is it an electrical issue that could start a fire? What can I do to prevent and/or fix it?

    Beside needing something in the microwave I would question if it's rated for that long of continuous use. Most people run a MW no more than 5 minutes at a time. I would assume the cheap ones used in RV's probably aren't designed for that kind of duration.
    thats why there are internal fans and power management systems. These microwave units are exactly the same as is found in a residence or apt.
