"no Co" coming back hours after a reset means the fridge ran but didn't see the temperature drop. With a new thermistor, that points to the cooling unit, not the board. The 637360/50808 kit is only for the 1210 and 2118, so it won't fix this. If your fridge is an N821, the replacement cooling unit is the Nordic 3381A, or the Norcold N8X replaces the whole fridge.
