When our ice maker stopped working we weren't sure why. Then we realized it wasn't producing any water to the tray, but the fingers still turned. At first i was sure it was a bad solenoid. But after checking that with a volt meter i determined the solenoid was good. I even connected the wire that goes to the front water dispenser and got water to pour into the ice tray. So the solenoid was good, it just wasn't getting any power/signal sent to it.
Then i found out that inside the ice maker there is a micro switch that send the signal to the solenoid, so i thought that might be bad. But after checking that with a volt meter, i determined that it was also still good. Then i realized that there is a tension screw that can be adjusted. And it turned out that the switch was too tight to the rotating cam and it was not sending power to the solenoid. Once the screw was loosened the switch became activated and water poured in. It was a simple fix that took 10 seconds, but diagnosing the problem took an hour and a half. Luckily though i didn't just buy parts and hope it fixed the problem.

The key is to narrow down the possible problems and eliminate the things that are still good. The solenoid was good, the switch was good, but it wasn't sending power, so it just needed an adjustment.
