DeanBoyack Report post Posted February 8, 2015 I have a '97 Dynasty with Norcold 983 3 way refer. When operating in AC mode it runs fine for a limited time, then it shows C2 error code along with beeping alarm. I have checked AC heating element, it is OK, so the problem must be on the power board. As I recall reading, a fix was to replace relay, there are 3 on the board, not having access to a schematic for the board it is almost impossible to trouble shoot. A relay is cheap compared to a new board. Any suggestions? Share this post Link to post Share on other sites
