Unfortunately, the N611/ N811 optical board kit, the 637775, has been discontinued, and there isn't a new replacement board. Before giving up, confirm the optical board is really the problem, since a bad power board, fuse or ribbon cable can look the same. Our troubleshooting guide can help. If the optical board is bad, the usual path is a replacement fridge, like the Polar N7XF for an N611 or the N8XF for an N811. 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.
