FWIW, the way that valve works is it is powered during trial for ignition, once the flame is ignited, power is dropped and the thermocouple holds the valve open. Shutting it off, the board send ~80 volts dc reverse polarity.
A common failure is if you hear the valve cycling a lot, it is due to oxidation on the thermocouple. When the board stops powering the valve, the gas shuts off and the board kicks in again. To fix, Unscrew it from the gas valve and polish the end with a pencil eraser, then snug it down firm, but don’t crush the insulating piece.
Those valves hardly ever fail, but I have a few of them.
