Freezer Won't Dispense Ice

I have a Frigidaire FRS23KF7A refrigerator that won't dispense ice. The door panel seems to be working fine; lights come on when they should, it dispenses water and the ice "flap" opens and shuts as normal. I hear a motor hum when I push the ice dispenser paddle but the ice isn't moving through the tray. I took the ice bin out, emptied it out and checked for jams, broken bits or frozen parts, but saw nothing. The ice auger, I think it's called, turns freely when I turn it by hand, but I get the impression it isn't turning when I try to get ice. Could it be the auger motor?
You folks helped me fix my stove, by the way. Thanks for that. :)
