This part is a replacement refrigerator drive shaft seal for your refrigerator. The drive shaft seal protects the auger motor from water and condensation that may leak down the drive shaft from the ice bucket. If the seal is broken, water and condensation can get in, causing the ice maker to fail. To replace the seal, first remove the ice bucket from your freezer. Then remove the two screws on the drive shaft holder, and use a pair of pliers to remove the drive shaft. At this point you can remove the seal from the drive shaft. Be sure to clean the area that the seal sits in before you reinstall the drive shaft. This part is white in color and is about an inch in diameter. The seal is sold individually.
