Hawkeye, this happens often on our cabinet installs. It could be a couple of things...
First, be sure the hinge plates are screwed tight to the cabinet carcase and are spaced apart the exact same distance as the cup holes on the door. The base plates must also be parallel to each other. If one or more are set at a slight angle in the cabinet, the door will bind. When installing the door, the hinge arms should easily clip to the base plates without much effort.
Next and most common, try adjusting the hinge side of the door out using the screw furthest back on the hinge arm. It seems counterintuitive, but the handle side door edge will move the opposite direction from the hinge side, in and out.
Next, it's rare, but occasionally the soft close brake in the hinge can be defective. Try turning them off, the door should close without resistance. If it does its a bad hinge brake.
Hope this helps.
