This part is the replacement door stop for your refrigerator. It is made of black plastic and is approximately 2 inches by 1 ½ inches in size. The door stop attaches to the bottom of the door and prevents it from swinging open and hitting the refrigerator cabinet. If your door opens too far, or opens with little resistance, it could be an indication that you need to replace the door stop. You will also want to replace the door stop if it is cracked, broken, or missing. This part is sold individually and is an OEM part sourced directly from the manufacturer.
