No, not really. OP's symptoms were 100% identical to mine. I'm just attempting to give him a starting point to begin troubleshooting. I have found that about 99% of the problems I've encountered with any of my RV's are "common" to a lot of other folks.
I've always following the path of least resistance. Start with the simple, no cost stuff first. Eliminate the most rudimentary, and work to the complex from there.
There are many other things that can cause an RV furnace from running properly. It's like saying, my car won't run. The engine started and then died. Where do you begin? The obvious of course? Do you have gas in the gas tank. Work upward from there.
Even the 4 possible faults indicated by the flashing light on the board could have multiple causes. Is the fan blowing fast enough to activate the Sail Switch correctly. A shot of WD40 on the fan might be all it takes. Low battery, weak battery converter, failing fan motor; any one of these could cause the red fault light to indicate this is the area of difficulty. But, it's a start.
Believe me, I'm no expert on mechanical repairs. But I have confidence in myself, knowing that anything on my RV is just nuts, bolts, screws, wires, and components. Researching a problem and finding possible causes and passing on our experiences is, after all, what these forums are all about.
I hope the OP figures it out and it really is as simple as blowing a dead bug out of the furnace orifice. Until he returns and gives an update of what he's tried or do so far, we can all only guess.
Meanwhile, it give the rest of us an opportunity to share our thoughts. Had it not been for a previous thread from a few days ago that I quickly brushed over or not taken the time to even look at, I would have been completely clueless. All the discussion from that thread sat in the back of my head. When I experienced the same problem, well ... it took a while for the light bulb to go off. Maybe all these discussions and possible solutions will help other too.
So, keep posting from your experiences. Everything helps. Believe me, these forums just saved me a ton of money, as I had already contacted my dealership for a date for a repair on my furnace. These forums saved me money and time on this problem. Share, share, share! We all benefit.
