This part is the replacement hinge bearing for your refrigerator. It is made of black plastic and is approximately 1 inch in diameter, and 1 ¼ inch in length. The hinge bearing connects the door panel and the door hinge and helps the door open and close properly. If you notice a clicking sound when opening or closing your refrigerator, or if the door won’t close at all, you may need to replace the hinge bearing. This part is sold individually and is an OEM part sourced directly from the manufacturer.
