The element test OK. gas works fine. should I replace the control board?

did you check the thermal cutoff (brown wire) for continuity? it acts like a fuse. when the electric side went out on our atwood 2-yrs ago (gas side comtinued to,work) i had advice to check it and sure enough it had blown. got a new one from a parts house and was back in biz. ez to check with a volt/ohm meter.
Couldn't have been the thermal fuse
If bad then NO DC goes back to circuit board so neither gas or electric would work
Since 2004 Atwood Gas/Electric have used common DC and circuit board controls
See wiring diagram.....thermal stops DC for both
Messing around with it...replacing it you might have made ECO Connection better
When on Electric a millivolt current goes from circuit board to ECO/Gas Valve and to ground
This allows the ECO to be part of the safety control loop
No millivolt thru ECO...no Electric operation
