Ice/Water panel dead on Ge Monogram

The 6 pad panel on the front of the freezer door that controls water/ice/lock/etc is completely dead. The door switches and lights on the inside are fine. From what I can tell, this may need the panel board replaced @$400-$500. Anyone have any ideas on this one? Could there be a fuse or something I can check out before dropping that much cash? Also, how do I get to the board? From the inside? Thanks for the input.
