Limit switch trips on Atwood furnace
My 1993 Jayco Motorhome Atwood furnace fan runs for @ 12-15 sec then the furnace ignites, it runs for a sec or two, then the limit switch trips.

The limit switch trips every time I try to run the furnace. That is why I say that the limit switch trips. I am not saying that the limit switch is bad.
I could not get the exact motor, because of age, but the description said it was compatible. I have not totally ruled it out.
Everything appears to be clean as far as debris. There was a dirtdabber nest in the exhaust area, but I cleaned it out. There appears to adequate coming out.
The motor comes on for @15 seconds, the gas usually ignites, runs for a second or two, then the limit switch trips. Sometimes the limit switch will trip before it ignites.
