FYI - If you suspect the control board as the culprit for the refig not working properly, you might want to check the connections on the 3 amp fuse where it plugs into the control board. About 3 months ago I replaced the control board because intermittent operation of the refig. The new control board solved the problem. After a thorough inspection of the original board, I found a loose connection on one side of the 3 amp spade mini fuse. I bent the board mounted tangs so the that fuse is now make good contact. I have not reinstalled the suspect board to see if this solved the problem. What lead me to believe it was a bad soldier connect or some other type of loose connection was the fact that I could tap on the board and the refig would start working normal for an hour or so or even a day before returning to the E0 fault code. Just my observations.
