Unfortunately the Norcold DC Board 637764/628669 has been discontinued by Norcold, and we don't know of new stock anywhere. On many 3-way models the fix is to replace the main power board instead, like the Norcold 628661 or the Dinosaur 6212XX, but the right option depends on your fridge model. If your fridge is also discontinued, our Norcold replacement guide shows which current model replaces it.
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.
