You need to add a lubricant like a silicone based grease to the hinges. Your model uses small cams on the tops of the hinge that correlate with cams on the bottoms of the door. Make sure the cams do not appear to be excessively worn down and when you apply your grease have a helper lift up on the door so that you can get the grease in between the cams. Good luck!
