I have the next larger size Norcold. I adjusted the doors by placing nylon washers on the lower hinges of each door that needed it. I am not sure on your model but there is a center panel on mine with plastic covers on the middle hinges that snap off. The hinges can be screwed out and the doors removed. Nylon washers from Ace or any good hardware. They have different thicknesses. Don't over do it as you can go too far.
I found a pictorial and parts list on the WEB. This should show how the center hinges are covered. The upper hinges on the freezer and lower hinges on the fridge section are more difficult to get to. Doors are very light. Job only takes a few minutes. You only need to remove the middle hinges.
