This is a replacement dairy compartment door for your refrigerator. The dairy compartment door opens and closes to allow access to the dairy items stored in the refrigerator door. Because it is made of clear plastic, the door can occasionally become cracked and broken. When the door is cracked, it will need to be replaced. The door measures approximately 15 inches in length and 6 inches in width. To replace the door, carefully remove the old door and insert the new door, lipped edge down. This product is sold individually and is OEM part from the manufacturer.
