Easy fix, unplug the fridge, disconnect the wire harness, remove screw holding unit to side of freezer compartment, this fridge has two set moldings that hold the rear of the icemaker in place and just slide off when removing or putting back on. They are on the same side of the compartment as the front screw. Remove the old unit and remove the fill cup and icemaker insert from the old unit. These unsnap from a tab in the back and on the side. Install the fill cup and side insert on the new unit. Connect the wire harness, slide the unit onto the side moldings and screw in place. On my unit I took a hair dryer and removed all the ice that had built up as a result of the leaking unit. Screw new unit in place and make sure the fill cup is aligned properly to the water hose.
5 minutes and its working great.
