Furnace blows fuse when started

[bdornbush]

I have a 2015 Escape 19 with an Atwood furnace. At the end of last season, it worked fine. When I was getting the trailer ready for this season, I found that the furnace would start blowing air then after a few seconds, it blew the 15 amp fuse. This is repeatable. I believe that this happens when the furnace attempts to light the burner. There is propane available as all other appliances work fine. Any ideas what might be wrong?

I got this fixed. It was a bad blower motor. I called a mobile RV repairman who diagnosed the problem, we ordered a replacement motor, waited a few weeks for it to be delivered, and he installed it. It works again. I recall that there were a few times recently when the motor seemed to slow down and speed up, and that should have been a warning to me that the motor was beginning to fail.
