Propane furnace blows out
The furnace on my 2006 Coachmen blows out when I try to run it while driving. IS there a "kit" of some sort to stop this, is this a normal occurance?

Update: Today (in minus 8 C weather)I tried to fire the furnace and after many tries it lit and ran. It kept showing 3 flashes (ignitor lockout)on each unsuccessful atempt. Since the furnace seemed to work in warmer weather I used my heat gun to warm the board and it now will not even try to lite. The blower cycles, the gas valve opens but it will not lite. After 3 attempts it shuts down and the LED flashes 3 times. So my suspicion is now a bad ignitor board. I am looking at purchasing a Dinosaur Fan50 plus pins board as a replacement.Any thoughts?
Yes, throwing parts is not a good idea until you have checked for a dirty burner. IF the Spark Electrode is cracked or defective and/or the spark wire is defective, you have spent money on a expensive board and no fix. You should hear the spark clicking, but you need to remove the spark plug wire from the board and verify the Piezo is indeed bad. IF the gas valve opens and the Piezo does not spark with the wire removed at the Piezo, then get a new board. Doug
