The Power Board 639593 you asked on is for the Polar N7/N8/N10, so it won't fit your N822. For the N822, the in-stock options are the Dinosaur 6212XX or the Norcold 628661. The older 632168001 has been discontinued by Norcold, and the N822 fridge is discontinued too. Norcold's replacement fridge is the Norcold N8X. See our replacement guide.
If the board has no power, check the 12V DC fuse on the board and the voltage coming in before you replace it. The optical (eyebrow) board usually doesn't need to be changed along with the power board.
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.
