Okay if it's all clear in your sure the icemaker is cycling (fingers turning) if what you say they seem to be in the right position, then the valve is the issue, these have to solenoids that open and close to put water in the icemaker and give you water through the door, the icemaker side is bad, you can't change the solenoid however you will need to replace the valve, you can order the valve at the following link
