This door bin (Bottom Door Bin, Refrigerator Door Bin, Door Shelf Bin, Refrigerator Door Bin) is a movable bin mounted on the inner door to hold food items, bottles, and jars. Over time, a cold refrigerator can cause plastic to become fragile and break down. This can lead to other issues in the refrigerator. When the door bin will not hold securely onto the inner door panel, it must be replaced.
