Dometic gas water heater won't fire
I did an ID10T error this past weekend. I had both ACs running and before we went out on afternoon hike I turned on the electric water heater so we could start showers when we got back. When we got back the RV was cool/both ACs running but no hot water. Light is on for electric water heater.. turned on gas (light for switch comes on, ours runs both electric and gas) and still no hot water. That's when i remembered I'm pulling too many amps between AC and heater. As everything else appears running fine, I checked the breaker for the water heater and didn't look tripped, but I reset it (didn't feel tripped either, just like a normal off/on of a breaker). At this point the electric started working but gas is not. Checking gas out and gas cuts on (hear/smell it), but the igniter is never firing. Heater cuts off gas, waits ~10 seconds, starts flowing again but no spark to ignite.
Is there some other reset to possible get the igniter to work or did I possibly brown out the board? If I browned out the board, why would electric work... I've let it sit for 2 days, turned off RV master electric, reset all the breakers, etc to try and reset something. Same scenario. Turn on electric, light on switch comes on and heater works. Turn on gas, light on switch comes on, gas flows to the heater but no ignition/spark. Everything looks fine, nothing melted, browned, etc on the board. I did read through some old posts where the board had to be replaced when it didn't ignite/spark, but I'm hoping I didn't just cost myself $100 doing something I should know better.
