Kenmore side-by-side model #25355679403 cubed ice dispensing problem?

My Kenmore model #25355679403 is still under warranty and I will call Sears, but in the interim, the cubed ice dispenser on the door suddenly is now only making "CRUSHED" ice and it won't send out cubed ice anymore. I tried taking out the ice bin, turning the ice maker off for a few minutes then turning it back on, and that did not correct the problem. We'd like to have cubed ice more so than crushed, but it does not seem to want to dispense just cubes anymore. Any ideas on what I can do besides just call another warranty call on this appliance, this will be the 2nd warranty call on it, do you think I have a "Lemon"?
