Temperature swings with a frozen drip tray, even on setting #1, usually mean the fridge isn't cycling off when it should. With a new thermistor, check that it's clipped on the right fin, since placement changes a lot on a 1200. The board is the next suspect. For the 1200, the Power Board 621271001 and the Dinosaur 6212XX are both in stock. See our too cold in refrigerator page. The 1200 is discontinued, and Norcold's replacement is the Norcold N15DCSS. See our Norcold replacement guide.
