Furnace problems - 3 lights, any solution?
Hi, my Atwood 8535 IV does not want to keep going. It fires up, it blows, the burner comes on but as soon as the electrode stop clicking, the flame stops. It tries 3 times then I get a 3 shot flashing...

OK, I had the propane fridge going, the oven at broil, the 3 stove burners on Hi and the water heater on. The flame stayed strong when the water heater came on. The flame on the burner has some yellow but mostly all flames where blue. I would say the regulator is good?
Now, for the sail switch, I read that if it does not work, the propane valves on the furnace would not come on. But my valves are opening because I hear a clic from them, then the electrode is clicking and the flame is there, I can fell good heat comming from the exhaust, but just as long as the electrode is clicking, as soon as the clikling stops, the flame stops.
How do you bypass the sail switch?
It is NOT the sail switch otherwise you would not get spark/gas valve/flame
The circuit board is not getting a flame proven signal....spark electrode!
It is either dirty, not engulfed in flame, is shorted/grounded, has loose/dirty connections at electrode/at circuit board.
The 'proof' signal is a milivolt...doesn't take much to stop it but w/o it,,,,,,,flame will not stay
Spark electrode!
