THIS is the spark electrode (and flame sensor)
Has to be directly in main flame...engulfed
When main flame is lit..a milivolt signal is generated thru 'flame ionization'. Signal goes back to circuit board 'proving' main flame lit off. If circuit board doesn't get signal....DC power to gas valve is dropped.
Doesn't take much to impede milivolt signal....
Dirty electrode
Electrode not in main flame
electrode ceramic cracked..signal goes to ground
wire from electrode to board...dirty/loose connections
Hopefully it is problem with electrode and not signal track on board.....new board
