Coil frosted up after a power outage and hasn't been making ice ever since. I used a blow dryer to defrost the coil and the freezer and refrigerator work fine, but the ice maker is getting stuck. It will rotate maybe once or twice and then freeze up in random positions. I can sometimes hear a faint clicking from inside, like a gear skipping. Water dispenser from the door works fine and I replaced the water valve for the ice maker already, before I noticed the fingers stopped turning.
