After I removed the Ice Storage Bin and viewed the plastic chopping blades, they were cracked. The two plastic blades (one component I believe) are cracked from chopping of the ice. I'm not sure what part I need to order. It might be the Ice Dispenser Drum, p/n AP3109184. Can you confirm that this is it? Can you also confirm that I don't need to order the whole storage bin, nor the Ice Dispenser Auger? Any tips on how to remove the drum and replace? Walter, May 1, 2011
