The 632441 is the middle shelf for N4XX/N5XX models with a serial number above 18721783. I can't confirm it'll work as the top shelf in your N400.3.
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.
