The existing auger was rusty and made the ice taste bad.

Removed the screws holding the faceplate. Then couldn't change out the auger so needed to remove all of the other screws in the unit and fully disassemble the icemaker unit. Should have marked the parts as I took them apart as I needed to find a parts diagram on-line to reassemble. Not sure that I put them back together right as the unit will not dispense whole ice cubes as it did previously.
