I replaced the ice/water dispenser unit. Using a very skinny screw driver in the small hole on the bottom dispenser control panel. I loosened the retaining hooks and pulled the panel forward. I noticed a minor difference between the new and old panel, which was a green grounding wire that was on the older unit. The new unit did not come with the wire, so I swapped the wiring harness to ensure I met the previous configuration. After reassembling everything, the dispenser worked perfectly.
