Can you turn the ice maker off?
To turn the ice maker on/off: Open the freezer door and turn off the ice maker. The On/ Off switch is located on the top right side of the freezer compartment. Move the switch to the OFF (right) setting as shown.
Are you storing anything other than ice in the bin?
Storing anything other than the ice produced by the ice maker can cause damage to the shutoff arm and/or internal mechanisms in the ice maker module. This damage could cause the ice maker to over produce ice.
NOTE: This also includes adding or storing bagged ice in the ice bin.
