Furnace

Good morning from AZ, sorry I have not replied quicker to what I found. I took the reply's here and looked into each, then I found this guy on You Tube, in one of his videos he made a comment about listening for the spark igniter from the outside exhaust port. And then showed how to test the duel solenoids that open the gas valve, I had the ohms he suggested but I wasn't hearing the tick tick of the igniter. So I pulled the gas valve out and hooked it up to one of my drill batteries as he did and both coils work and air passed through the gas valved. I decided to pull the igniter housing out as he mentioned and there it was, a mud bees nest a crossed both igniter prongs. Cleaned and reinstalled and everything works perfectly.
