Hi all ,I have a truama ultrastore and on the gas the green light is coming on ,it sounds like it’s about to fire up then the red light comes on and no go ,I have changed the board with my mates (same model ) and it was no different,so in short it’s got 12v power going to it ,the fuses on the board are fine ,board is fine ,and it’s got gas going to the unit ...........lazy /dodgy solenoid? Not opening to allow the gas through perhaps? Any input welcome
