The Board Kit 637779 is listed for the N621/N821, so it's made for the N821FRT. It has been discontinued by Norcold, so it's only available while our remaining stock lasts. The in-stock alternatives are the 628661 and Dinosaur 6212XX. The N821 is discontinued, 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.
