dw9663 - yes I solved the problem. It was not the gas valve. It was indeed the flame sensor. This is part of the pilot assembly, and my plumber buddy happened to have a pilot assembly that I put in to try.

You can indeed confirm it is the flame sensor with a meter. If I remember, you'll want to check at the termal furthest back and the one closed to you (I forget the numbers).

If it is the flame sensor / pilot assembly, you'll see 24 volt when the gas valve opens, and then at flame out, you'll see voltage go to zero.

In any case, if your shooting at it, I would shoot at this first and replace the pilot assembly.

Good luck.
