Help...Furnace issues

In November we took out 2016 Montana High Country camping, and the furnace would not work. Initally, the thermostat would blow the 15 amp fuses within 3 seconds of turning the thermostat to furnace. We bought a new control panel because we did discover that the one we had was trashed. This allowed us to turn the thermostat on to furnace without it blowing the fuse, but still no hot air. You can hear the blower, its just cold air coming out. We had no issues with using the stove and we had hot water, just no hot air.
We've searched the internet, our manual and all that came with it, and their is no info on the furnace. We have no clue the brand or anything. Anyone else experience this, and if so what did you do?

So, new info, my husband has been messing with it again this morning and now it is back to blowing the fuses.

A few months ago I had a similar problem with my furnace. It got to the point where the fan would come on, but no fire. I did several things to eliminate the problem, but still didn't know or understand enough about these furnaces to solve the issue. I had good gas flow and pressure. Beyond that, I was pretty much clueless.

Alas! My old friend YouTube came knocking at my door, and I found this YouTube video:


The location of my sail switch was right on the front, easy to remove and I tried cleaning it. Well, that did not work. I ended up going to my local RV dealership that sold Keystone RV's and they had the switch. There was a slight assembly required, but I got it. I attached the wires, screwed it back on and ... whaloa! It worked. The furnace has been running flawless ever since.

In fact, before I changed the switch, my furnace would always attempt to fire. It would finally fire on the 3rd attempt. It was like this from the day I purchased the camper. I just thought it was the nature of the breast. After replacing the sale switch, it now fires on the first attempt, even after the propane tanks have been turned off for a while.

Our 2017 has a black self resetting fuse for the furnace not sure what they had in 2016 but if you need one you can only get it from Atwood.
