If holding the off button doesn't shut it off, the front control (optical) board or its ribbon cable is usually the problem. Try a hard reset first: disconnect 12V to the fridge for a minute, then reconnect. The Board Kit 633275 has been discontinued by Norcold. For the 1200, the power board 621271001 and the Dinosaur 6212XX are both in stock. The 1200 is discontinued, and Norcold's replacement is the Norcold N15DCSS. See our Norcold replacement guide.
