For an N611FLT, the power board depends on the serial number. Below 9056491 it's the Power Board Kit 621991001, and above that it's the 628661. Both are in stock. Your serial number looks like it has an extra digit, so please double-check it. The Board Kit 637779 you asked on is for the N621/N821, and it has been discontinued by Norcold. The N611 is discontinued, and Norcold's replacement is the Norcold N7X. See our Norcold replacement guide.
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.
