Words like ignitinator are a tip lol and the long yellow wire has 24v and the shorter yellow wire has none.

The gas valve is getting 24v on the red wire and 12v on the black. Do you guys think the valv is bad? This is the first one wire spark ignition system I have seen. Red wire? Black wire? Poof?

Just so you know, this forum is an open forum. No one has been vetted here, and that's why we don't post a lot of technical information because people do try to slip in here.

I bet it was a bad ground in the flame rectification "circuit" which was incidently corrected when changing the board. This assumes, of course, that he had 24v across MV/PV and MV for a few seconds until the control stopped it for lack of uA coming back. He didn't say if he cleaned the flame rod...
And why are we bring back a post from April for something that's already been fixed?!

We are both self-taught for the most part....I had never heard the term "flat" used to describe a system out of refrigerant until about 2 years ago.....Terminology alone, is not grounds to declare someone a "slack-assed tech"....

Thanks guys! I am sorry for not updating sooner! I am not just a home owner trying to do it myself. Markvilleman put me on the right track. I went back and checked the honywell board and it was bad. Changed board heat fired and everyon was happy! Now A/C season has started early down here in Memphis TN and I am loving it! Not much of a winter here so I am well rested. Thanks for the advice guys and Ill check back in sooner so I am not labeled a diy.
had a keeprite gas unit that would get to the point of lighting the pilot then main valve opened and a good flame would be there then die back. Sometimes it would burn for a few seconds or few minutes... found out the gas company had a bad meter/reg and it was choking off the supply. The guy was way out in the country.
He's in a tech-to-tech forum.
we can't help giving advice. W are very sympathetic.
no advice given here he would need to be a tech to do or even know what I said besides checking if he has fuel in the tank if its lp we never received that answer.

If I read your valve model correctly, it's an intermittent spark valve that can also be used as a universal valve. In your application, after the inducer closes the pressure switch, a Honeywell S8610 (or similar) module should open the pilot valve and initiate spark to light the pilot. It probably has a Honeywell ST9120 control board as well, to control the inducer and the blower. After the pilot proves, the module will open the main valve. The valve should have three terminals..."PV" (pilot valve), "PV/MV" (common), and "MV" (main valve). Selling them a new furnace won't teach you a thing. Figure it out and learn from it. Come back here for more help if need be.....we're here for you.
What kind of control board u have? Is it a black box build of Honeywell smart valve? If positive,then check the board first before u condemn the valve. Good luck.
I've done the same!
I dont think he checked the gas pressure prob lp with no gas in the tank LOL
