The ice dispenser door would not open or close.

It was actually very easy. You simply remove the display cover (you just want to be careful removing the display cover so as not to damage the lower part which secures it to the door), unplug the wires, remove the inner cover (4 screws) to gain access to the solenoid. Remove the 4 screws on the solenoid replace with the new one, put the inner cover back in with the 4 screws that were previously removed, plug the wires back in and then replace the display cover.
