Similar problem seen just now. Open-circuit solenoid coil on gas regulator valve. Just off to look for another one. Solenoid coil easily replaceable. Just held in with a spring clip. There should be no need to disassemble valve or replace it. Just measure coil resistance, should be about 2000 Ohms.
