The 633287 kit lists the N641, but not the 3-way N641.3, so I can't confirm it'll work. For older 3-way N641.3s, the power board is the old 621270001, which is replaced by the Dinosaur 6212XX.
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.
