The NR751BB was made to fit the DE0751 cutout, so I can't confirm it'll drop into a DE251D space. It's discontinued, and the Norcold DC751 replaced it. Send us your opening measurements (height, width, depth) and we'll check. If it fits, a handy owner can usually do the swap.
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.
