Heater not working - what to do next?
I know there are a lot of threads about this and I think I have read them all. I have a 2016 Thor PD31 Class C. I have not had it that long but I have had several issues I have fixed but this one I need some help on. The heater. Its an Atwood AFMC30141. Its been working fine until about a week ago.
The blower kicks on for a minute and then it fires, but only for a few seconds and stops. I am getting a three light error on the control board, ignition lockout fail. After reading a lot of fourms I have tried several things, mainly I replaced the OEM board with a dinosaur board (the old board looked like it had some water damage) I ordered a new sail switch also but its not the same one, the "sail" is not the same, not as wide as mine. Neither of these solved the issue. I cleaned the contacts, I closed the propane and slowly opened it several times, the gas stove works fine.
I am guessing the flame sensor is not detecting the flame, I know its there because I feel heat for the few seconds when it kicks on. I read somewhere to block the vent but I am not sure about that.
Can anyone direct me to the location of the flame sensor? I cannot seem to find it in the manual.
Any help would be greatly appreciated, this is our first RV and the community is pretty awesone,
