Can I jump fridge gas valve for TS purposes?
Fridge in the "new-to-me" camper is a Dometic RM3604 3 way. I was unable to check the function of any of the appliances before purchase of the camper, so I do not know when it was last operational. ...

Old-Biscuit, yes, that is the same manual I've been working from, along with another from Dometic that I think it for an older model 3 way in the same series, but has a handy flow chart for troubleshooting purposes.
I had gone to "it's a board issue" since I wasn't getting any voltage on the AC element output, was getting low voltage on the DC output, and hearing the gas valve cycling. That valve is cycling at the same rate that the igniter is firing, but it doesn't appear to ever be flowing any gas through. When the gas valve is cycling, it's doing so with very loud clicks, which I don't know if that's normal or not. It's loud enough that I can hear it inside the camper as well.
I also found 3 wires on the 6 pin connector had melted insulation, as well as the 2 pin wiring harness going to the gas valve. I've since repaired those wires by cutting out the damaged sections and splicing in new wires.
I didn't see any obvious fuses on the control board, though I didn't inspect it throughly either. There may well be SMD fuses that have failed. As a point of reference, I'm a low voltage/electronics tech by trade, so I have a tendency to dig into this stuff deeper than most people probably would, lol.
I'll take a closer look at the board tonight, and pull the gas bits for further inspection and cleaning. Thanks all!
