First thing to check is to see if the optics are working properly. This is the red flashing light on right hand side of freezer wall. Close the flipper door, be sure not to block the beam, and the light should go to solid red. If it does then the optics are ok. If it continues to blink then that is your problem. If optics check ok then pull ice maker out and remove the white plastic cover. It just pulls off. Look at the center of the gear wheel and see if one of the plastic tabs is either broken or if they are sort of twisted and touching eachother. If any of these things with the gear have happened then that module will need to be replaced along with the ice maker thermostat. If your not sure how to replace these parts then just replace the whole ice maker. That is much easier and not much more costly.
After changing the parts or the ice maker out follow these steps to start the ice maker thru a cycle. 1. Remove the ice maker from the cradle but leave the harness connected. Remove the front cover from the module. Unplug the refrigerator. Get a small jumper wire with bare ends and jump T and H on the module, leave the jumper in and set the ice maker on the shelf. Close the door. Now plug the refer back in and wait 30 seconds. Open the door and the ice-maker should be cycling. Remove the jumper, put the module cover back on and set it back in the cradle. The fill should take place when the ejector blades reach the 12:00 position. Follow these steps exactly in order

Your unit has infered sensors on the frezzer left and right walls. There is a diagnostic test sheet brown in color in your kick plate.All you have to do is open frezzer door look on the right sensor it should blink twice followed by a 1-2 sec delay,if that is good press in flapper door on right sensor do not block path of infered beam you will not see a beam its invisable.Once you hold in flapper on right sensor the led should be solid.If solid optics are good if not solid led replace optic sensors
