After installing a new board from Dinosaur (I went with the Fan 50), a new electrode and a new fan limit switch (this is the one that shuts off the fan after the furnace cools down). The furnace lit twice in a row with out hesitation. I think my old board was not producing enough spark, or a late spark. There is a neon light on both boards, on the new board this neon light lights up when spark is produced, I never saw the neon light on the old board light up. Just a word of note, if you install a new board or upgrade as I did. Read the instructions carefully, if I would have read them closer the installation would have gone much quicker. With the Fan 50 board and an older furnace, the extra orange and red wires that come with must be hooked up according to the instructions the board will not work, even if you get the fan to kick on.
On to the next project...
