If everything on the display works except the on/off button, the button contact on the 637081 optical board may be worn out. Before replacing anything, check the ribbon cable between the front board and the power board for a loose or corroded connection. Unfortunately, the 637081 has been discontinued by Norcold. Our tech support service can help you look at other options. 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.
