Any ideas what is going on or what I should be looking for to fix?
Not familiar with your trailer....so....if you have an Atwood with both electric and lp .... try the electric approach to see if you can gen hot water that way. If so, I'd be reluctant to swap a board without some more tests. That said, a good many have done the dinosaur board swap as a pre-emptive move. Other's like my self have one in the spare's box. You aren't far from Jim's Trailer Sales, so it may be a good idea to take it to them and see if they can trouble shoot in the parking lot for you. Or, there's a couple of spots on the interweb that have the Atwood H/W tank Service Manual as a pdf file. Good to have if you insist on DIY.
It may only be an anomoly with my trailer, but if the GFCI has tripped...the H/W doesn't heat with LP.
