The NR751BB has been discontinued by Norcold. The current replacement is the Norcold DC751 (2.7 cu ft), which is in stock. Since you're replacing a DE-451, compare the cutout dimensions and door swing on the DC751 product page against your opening before ordering. 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.
