Did you ever get it to work? Our ice maker went out within the first month. The repairman brought a pump, which goes in the back, you have to pull the fridge to get to it. He asked if water was coming out, Yes. Then he replaced the ice maker, been golden every since.
For what it's worth, he did say there was a problem with a batch of fridges and most times he has to replace the the pump too. He gave me the new pump free of charge, and said it was part of the warranty replacement program. I still have the unopened pump. Hopefully I won't need it.
