1 post and you guys are giving advice ????????? I think this homeowner should call a reputable heating company and Quit playing like he is a tech

He is in a tech to tech forum which means he previously had to get his post to 15 before aloud to come here right? Give the new guys a break, I am still new myself and dont need constructive criticism, we are trying to make a living just like everyone else.

dude that character only has 2 post, where do you get that kind of bad info.

thec2tech is a back door for homeowners that should have never been opened.

there is no vetting for tech2tech

clues you are dealing with a homeowner:
1- not near enough info in the first post
2-terminology
3-wording of problem
those could also pertain to a slack @ssed tech to, which there is no difference between the two

i'm just old and gruppy, wtf do I knopw

Dad started doing this when I was ten, and I'm 52 now. 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"....

And why are we bring back a post from April for something that's already been fixed?!

Why not?

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...

Why the heck are you raising a thread was buried back in April?

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.

Guys I need some opinions this am. Working on a Tempstar NUG5075BFA2. It has a VR8204M1075 gas valve. The t-stat calls for heat, inducer goes and closes the pressure switch. They the direct spark ignightor starts sparking and there is a poof of gas that comes from the piliot tube that imd goes out. 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?

I gotta go against John in this case.

This guy needs to talk with his boss, but my bet is that he doesn't have a boss, because he is not really a tech. Apparently, English is not his strong suit, either.

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