The Norcold Board Kit 637779 is listed for the N621/N821 models. I can't confirm it from that serial number, though, since it doesn't match the usual Norcold format. This kit has been discontinued by Norcold, so it's only available while our remaining stock lasts. The in-stock 628661 and Dinosaur 6212XX are other options for the N821. The N821 fridge is discontinued too, and Norcold's replacement is the Norcold N8X. See our Norcold replacement guide.
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. You can also browse www.rvfridgeguys.com.
