Attwood water heater not lighting

So the next woe to figuring out the kinks lol. Went to light heater today and it will not light with gas or electric. Checked continuity on fuses all good . Im thinking control board might be shot . Its model GC10A-4E

Update. So I put a new thermostat and echo piece in along with a new igniter. Now I hear it kick on on the 120 side w generator running but still won’t ignite on 12v gas side . Wondering if it could be a bad board
