Your N621 with that serial number would have originally had the older style board, the 632168001, which Norcold has discontinued. The Dinosaur 6212XX is an upgraded replacement for older style boards, but since yours looks different, send us a photo of your current board and its part number so we can confirm before you order. Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you.
