The Lower Door 634063 is listed for the N621SS (stainless steel, smooth interior). I can't confirm it fits your N621FL, which may be a panel door, or which side the hinges are on. It has also been discontinued by Norcold. The N621 fridge is discontinued too, and Norcold's replacement is the Norcold N7X. See our Norcold replacement guide and our N611/N621/N641 parts page.
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.
