It will have all the parts you need,and cover all possibilities for your complaint, and instruction sheets to assist you in the repair.

Access is relatively easy,basic hand tools, and a little patience.

To remove the dispenser trim panel,

Unplug the power cord, or access the wire harness inside the top hinge cover of the freezer door, and disconnect harness.

On the bottom outside edge of the panel, you should find 2 slots molded into the panel, you'll need to pry out on the slots and push down on the panel, to release the mounting tabs in the door panel.

Remove the screws holding the switch panel to the dispenser body, and you'll have access to the flapper assembly parts and can dismantle and replace the parts as necessary.

Good Luck,
:) :) :)
