The tab that the tray door rotates on broke. This is the second time it broke. Very bad design.

I did it quickly since this was the second time it broke. For easier access, remove the glass shelf above the drawer and the two plastic strips that hold it in place. Remove the two screws (yes, there are three screw holes on each side, but there are screws in only the front and center positions; probably to save money on screws) with either a flathead screwdriver or a socket wrench, which works better. There are two tabs on the end cap that slide into slots in the back of the refrigerator. There is also a plastic retainer on the side of the refrigerator in the front that attaches to the end cap. Gently lift up the front of the end cap and pull forward to remove it. Then unscrew and remove the metal slide bars and install them on the new end cap. Then do everything in the reverse order. Fit the two tabs into the slots in the back of the fridge, then position the fitting over the plastic retainer on the side of the fridge, and gently push back and down. Then screw the end cap back in place. Repplace the two strips for the glass shelf and then slide the shelf back into position. The last thing is to refit the tray door onto the tabs on both end caps. Slide it into position onto one end cap tab, then GENTLY push the tab back on the other side and fit it into position on the tray cover.

This sounds more complicated than it is, but there are no instructions with the replacement piece, which in my opinion is bad for customer relations. This is also a really bad design. If you accidentally leave the tray door open when you close the refrigerator door, the refrigerator door will hit the tray door and break one of the tabs.
