For the N621, the in-stock options are the Norcold 628661 and the Dinosaur 6212XX. Depending on your fridge's age, the 628661 may need an adapter that's no longer available, so send us the serial number and we'll confirm which is best. The N621 is discontinued, and Norcold's replacement is the Norcold N7X. 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.
