Yes. For an N611RT with a serial number below 9056491, like yours, the Power Board Kit 621991001 is the one to use, and it's in stock. The Optical Display Board 621988 you asked on has been discontinued by Norcold. The N611 is discontinued too, 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.
