Initially thought that the lower door hinge needed an adjustment after 13 years of use. After further investigation and research, the upper and lower door closure cams needed replacing. I ordered parts on a Monday afternoon with standard shipping and they arrived the next day!
The videos on how to replace these parts allowed me to lay out everything I needed to make the repair. Prep and clean up (gather tools, remove items from door shelves to a cooler, etc.) took longer than the actual repair. Required only two tools to switch out old and new cams. Door now operates as if new!
