I have a Lennox G12 that won't stay lit. You can light the burner, turn the gas valve to the run position, the burners will light and burn for a few seconds. Then about the time you would expect the blower to turn on, the flames all go out ( burners and pilot light). I also noticed the gas valve won't turn back to the "OFF" position. I'm guessing the gas valve, but then why do the burners light? Can anyone please give me some advise on this?
Any help would be appreciated.
Thanks!
