Ice Cube Tray Shelf
(on some models)
Some models have a small separate shelf
for ice cube trays.
Ice Trays and Bucket
(on some models)
To remove ice cubes from the tray, place
the tray upside down on the bucket as
shown. Press down on the tray and the
cubes will pop out.
Large Ice Bucket
(on some models)
This bucket is required when using an
automatic icemaker. When installing an
icemaker, the upper left basket must be
removed in order to make room for the
large ice bucket. If an icemaker is not
installed, the bucket can be removed
to provide more capacity in the freezer
compartment. For U.S. models, the bucket
is included with the refrigerator. For
Canadian models, the bucket is included
in the optional icemaker accessory
kit (IM4-1).
