The ball of ice was forming there but the coil was replaced. No one seems to be able to get the right part replaced. The parts so far replaced have been the coil where the ice was forming and the control kit for turning temp 1-10. The freon has been changed for this model and the new freon was put in the compressor. There is no ice forming since the part was replaced but the refrigerator still does not keep below 45. It started to for a few hours went down to 38 but did not stay there and has not gone down since. But since the evaporator fan only runs less than half the time could that motor or switch need to be replaced so it can circulate the air to keep the refrig cool. I just taped the switch to make sure it stays running. I will see if that cools the refrig down.
