Most likely, yes. An N621 with that serial number would have the older style board, and the Dinosaur 6212XX replaces those. Check the part number printed on your current board to confirm. 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.
