It is easier
to work on this type of unit by first removing the entire ice
maker from the freezer compartment. The unit is usually mounted
to the freezer case by two or more screws. Remove the bottom screws
first. While supporting the ice maker, remove the remaining top
screws. Unplug the ice maker from the freezer cabinet if you have
not already done so.
Along the
edge nearest the shutoff arm, a pin protrudes through the mounting
plate (labeled "A" below). The arm pin has a spring
under the mounting plate. Reduce the tension on the spring by
moving the shutoff arm into the "on" position, down,
against the ice maker.
