On the 3-way N641.3, the board depends on the serial. Below 8938727, it's the old 3-way 621270001, and the Dinosaur 6212XX is its replacement. I can't confirm the 628661 handles the 3-way DC side.
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.
