The Lower Door 635647 is listed for the NX841/NXA841, and I can't confirm it fits the NX811RT. It has been discontinued by Norcold, so it's only available while our remaining stock lasts. See our NX811/NX841 parts page. The NX811 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.
