"no Co" means no cooling. The fridge ran but didn't see the temperature drop, and that usually points to the cooling unit, not the power board. Check that the heat source is working (flame on gas, heater warm on electric). If it is and the fridge still won't cool, the cooling unit has failed. For the N641, the replacement is the Nordic 3361A, which is in stock. The Norcold N7X replaces the whole fridge.
