The icemaker does not make ice. Two months ago, the freezer door was left slightly open and the entire freezer contents defrosted with water on floor. Icemaker had worked fine previous to this event. The water to refrigerator has never been disconnected or turned off. Water filter has been changed and I have water at door dispenser. No water is coming to the ice maker, the switch is "on" and there is nothing blocking the sensor unit. I have waited more than 24 hours for the unit to go through a cycle. Ideas? Anything I can try before I replace the entire unit? Thanks! zappy
