Norcold used several display/board versions on the N3150. The Optical Display Panel 638233 and 690872 have both been discontinued by Norcold, so they're only available while our remaining stock lasts. Before replacing the display, confirm 12V DC is reaching the power board and check the fuses and the cable between the boards. A blank display is often a power problem. The N3150 is discontinued, and Norcold's replacement is the Norcold N4150. 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.
