New guy here! I've been googling my issue, but can't match the symptoms... My Atwood 93756 won't light. I replaced the igniter. When my wife hits the button inside, I can see the igniter spark (once). It will light if I use a BBQ lighter, so I know there is gas. In fact, once I get it lit and gas is flowing, if I turn if off and back on right away, the igniter lights the gas right up. Once it's off and cools down, it sparks but won't re-light. But again, I can manually light the gas. Should my igniter be sparking more than once? Any advice? THX!
