The auger in the bucket assembly appears to be rusted. Cleaning the "rust" on the auger seems to clear up the deposit somewhat. Is this "rust" or a different deposit problem? If I need to replace a part(s) should I replace the entire Ice Bucket and Auger Assembly or just the Auger? Can the Auger by itself be replaced? Ice making is not compromised by this problem. Thank you for your assistance.
This would be rust on the auger and the auger WR2X9481 can be replaced as an individual part. To replace the auger, you would pull the bin out and take the front cover off. To take the front cover off you will remove 2 screws at the bottom of the bin. There may also be 2 screws on the inside of the bin to remove. Once removed you will need to take out the screws holding the metal bracket in place. Remove the screws that hold the crusher housing and take the clip off the front of the housing. Lift the housing off. You will then unscrew the nut and pay close attention to how the the blades are in place. These will need to be put back exactly how they are on. Once off you can put onto the new auger and reinstall. There is also the bucket assembly WR17X10424 if you would prefer to get instead of tearing down the old bin.
