For an N821 with a serial number above 9126825, the rear power board is the 628661/ 50723, which is in stock. The front optical board for those serials, the 628974, has been discontinued, and there isn't a replacement. Before replacing either one, make sure you know which board is bad. Our tech support service 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.
