With serial 9863889, your N822 is above 9126825, so the 637779 kit won't fit. If it won't run on AC or LP, the rear power board is the most likely cause, and the 628661 power board is in stock. The matching optical board (628974) is discontinued, so if the front board is also bad, the Norcold N8X is the replacement fridge.
