That section of evaporator pipe should be well below freezing, and some frost on it is normal. If the freezer is at 0°F but the fridge hangs at 50°F even with good airflow, the cooling unit is weak. The fridge evaporator is the last part to get cooled. The 636411 for the N300 series is discontinued, so if the unit is failing, the Norcold N4150 is the current replacement fridge.
