Unfortunately, the N811's optical board kit, the 637775, has been discontinued, and there isn't a replacement. Before concluding the optical board is the problem, check the power board, fuses and ribbon cable. Our troubleshooting guide can help. 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.
