Hello Samsung RB193KABB
(may be Canadian model?) top fridge/bottom freezer, hinge on right side as you look into fridge.
The fridge door stop is starting to drag on the top of the freezer door plate. I believe the bushing/washer/cam (or what ever it seems to get called) is getting worn down, causing this to happen. The upper bushing on the fridge door is notched and the lower is just round.
I think the photos will explain this better if they will attach.
I can not find the right part numbers. If not, I thought I could just get a small nylon washer and raise the door a small bit to prevent the dragging. I would just keep what is there and add the washer?
