. Maybe bad solenoid or board. Also check for DC power at the heater.
This morning I tried igniting the heater again and it fired 2wice - it didnt go the 3 tries I am done, just 2 tries. So start wiggling wires and Poof it tries to ignite then goes out. Fidgit with it a little more and now it seems to be working ok. All connections seem to be rather tight (hard to pull off - so much so that I thought I might break something if I pulled too hard)
Sooo.... We'll see how long this lasts or if it starts to crap out again. Getting to learn these idiosyncracies - I am glad to see that they arent really complicated. Just a bit of a learning curve.
