A missing or partial display, like just an "n", usually points to the front optical board, not the rear power board, and the two have to match. The 637779 kit is discontinued. It was for N62X/N82X fridges with serials below 9126825. If your serial is above 9126825, the fix is the 628661 power board with the matching 628974 optical board. Email us your serial number at info@rvfridgeguys.com and we'll tell you exactly what fits. If the older kit is what you need, the fridge would have to be replaced; the Norcold N8X is the current replacement.
