Chances are you have a dual solenoid gas valve. If you have an ohm meter pull the wires off of the valve and check for resistance on the coils. I would bet one one or both are open. Resistance should be approximately 80 ohms give or take. I had one of my coils open some years ago. I was able to unwrap a couple of wraps and resolder. Eventually I bought some magnet wire and rewrapped the coil. It's worked fine ever since.
