When it does fire up, the burners fire and glow great all the way across so i think the signal runs through to fire it, then runs, then shuts down? What sensor or wire are you talking about that could be bad? Thank you When it does fire up, the burners fire and glow great all the way across so i think the signal runs through to fire it, then runs, then shuts down?

It will fire and run but it shuts down because it dosen't rcognise the flame. The sensor is the flame sensor I described before depending on what sort of ignition system you have (standing pilot or glow plug) The wire is the one that runs from it to the ignition control. If it dosn't read a signal it shuts the gas down. So yes it will fire as you described in the orignal problem but if it dosn't fire it will shut the gas off. Even if it has fire it won't nesserly read the fire and shuts down anyway, this falls under the heading of the problem. So at the risk of repeating myself. The sensor will be found on the pilot assembly or in the firewall just above the burners about in the center of the wall. It will fire and run but it shuts down because it dosen't rcognise the flame.
