I had the same issue and tried the same corrective actions with no success. I emptied the ice bin, shut the ice maker off and unplugged the refrigerator. After 10 minutes I plugged it back in and turned the ice maker and within 4 hours it was making ice again. It is working fine now. I think somehow the ice maker gets out of sequence and by unplugging it you are resetting it and is restarts the sequence.
