Is there some kind of thermal protection inside the unit which can be reset?
No. It's probably the start or run capacitors. Do a search here. There is a really in-depth thread on how to troubleshoot and repair them.
I have one in my coach. The only ones I have ever seen were Coleman. A few different models but all pretty much the same.
I'm not going to go into any of it because the thread that is 5 or more pages long covers everything you would ever want to know about basement air.
