Did the water freeze yet? If not then you may have antifreeze in the mold. If it has, the ice sensing arm should be down for it to continue. If the arm is down and you have power, as was mentioned before, you either have a broken gear or bad mold thermostat. Let us know more info and we might be able to help.
