On the how to replace the circuit board, it is not that bad if you are electrically friendly. Since you figured out how to jump out the AC and furnace interlock, you done good.
This post may help on the how to replace the board with pics
Now on the part numbers of the new board, I have to dig into the part numbers to help sort this out better. Years back I did buy a new control board. They kept obsoleting the boards along the way and another one replaced it. I'm out of time tonight to help dig deeper but can help later is you still need it.
Your ac part number you said
Did you miss a 0 near the end of the part number, like it should be model# 5791550
3 Please check this and report back. OR is there a 1 at the end of the number like this: 57915531
The start of the part number shows it is a 13,500 btu unit which would be what Sunline would of put in your camper but the other numbers tell the rest of the story.

Go into the online parts catalog, in the "Choose category" box, that is a pull down, select "Air Conditioners"
Scroll down to "Dometic - Brisk Air Model"
Scroll down to your model number. I can only find the 791550
3 part number or 57915531
. If you go in there, they show this
If you don't find the item your looking for please call 1-800-755-4775
That most likely will be a place called RV Dealership who is the supplier of these parts. That company will give PPL credit for the sale, but they will ship the parts to you. http://www.rvdealership.com/rvdstore...rNumber=885555
Go under "Questions/Polices" pull down and it explains it some. They are based out of Elkhart, IN
I have used them before and had good service. You may just need to call them and find out what the latest PC board for you model is. Let me know how you make out. I can help dig some more if needed.
Hope this helps
