Norcold N841 board problems

I am a new member - lured in by the excellent thread on restoring the finish on my 1994 Winnie Adventurer.

 

I am have been having a refrigerator problem - kept blowing the 5 amp glass AC fuse when turning the fridge on.  I figure it had to be the board, so ordered a replacement.  I ordered the kit that includes the optical control board, and replaced both boards.  It didn't fix the problem.  I then searched the web some more, and realized that I should have checked the heater element first - it was bad.  So I replaced that and it worked - the fuse doesn't blow any more.  But now I have a new problem!  The fridge turns on fine, but only cycles AC and AU - no FL.  Then of course in stops on AC and goes to the little dot indicating that its on.  But when I press the Temp Set or Mode buttons nothing happens.  And a couple of minutes later I get the 'dr' fault - although the doors are securely closed.  I realize that I probably won't get this fixed on time for my trip this Thursday (2 days away!) and I'll have to camp with coolers.  But I'm hoping to fix it soon enough for December camping.  I'd be grateful for any suggestions.
