Hi Dan, we need the model number of your refrigerator. You posted the ice maker part number in your model number.
Is there ice in the ice maker tray but it won't cycle the ice out?
Put a thermometer in your ice maker compartment and see what the temperature is reading after it sits awhile. It has to be 10 degrees or less at all times or the ice maker WILL NOT cycle.
If your temperature is good, Read post #5 on HOW TO JUMP T and H to do a FORCE CYCLE in this thread:
I have a 5 year old Kitchenaid refrigerator Model: KFXS25RYMS5 and the icemaker started giving problem couple of months back. It started with less number of ice cubes and then started thinning out the size of ice and finally it stopped completely. I removed the icemaker and didn't find any trace...
