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...

Likely a flakey sail switch. Intermittent action of a flakey switch will cause the furnace to try to start, then fail. You can TEMPORARILY jumper it with a wire to see if that fixes the problem, and proves the switch is indeed bad.
