Atwood Water Heater Won't Operate on Gas
My LP/110V Atwood works great when I'm hooked up, but doesn't work at all on gas. Is the 110V system separate from the LP side because the 12v side doesn't seem to be getting power (when I remove the ...

It looks intact but doesn't seem to be moving current along, I figured best thing would be to just order a new one. That and the thermostat are the only two things holding up the works (no light on the board seems not to be an issue) so I ordered both.
So my only remaining problem will be no heat, but at least I live in Florida.
Light should be a Fault Light------comes on when spark occurs but no main flame lights off.
With main flame lit.....pull one of the RED wires off ECO and see f light comes on?
How did you 'test' the thermal fuse and/or t-stat?
Unplug thermal fuse and plug brown wire directly onto t-stat.
If t-stat is good propane will work
Or you can plug thermal fuse into brown wire from t-stat going back to circuit board (bypassing t-stat). If thermal fuse is good propane will work
Thermal fuse is one time deal....blows at 190*F
Must replace when it blows
T-stat Opens at 140*F and Closes at 110*F
ECO Open/180*F--Close/150*F
ON/OFF Switch..that switch should just be for propane operation.
Electric operation should be via a local switch on cover over electric element (backside bottom of WH Tank)
If someone rewired the 12V DC Propane switch to operate the electric element it has 120V AC and 12V DC to/thru it
So what's up with furnace?
Which model Atwood and what is it doing/not doing??
