If the N611V runs nonstop and freezes even with a new thermistor, make sure the thermistor is clipped on the right fin and hasn't slid down, since placement matters a lot. If it's in the right place and the board still won't cycle off, the board is the next suspect. The 628661 is in stock. Also check the optical board for a stuck button. See our freezing everything page. The N611 is discontinued, and Norcold's replacement is the Norcold N7X. See our Norcold replacement guide.
