I don't recognize kit 663294A. The N611 optical board kit (637775) has been discontinued and isn't available anymore.
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.
