Filter

An old filter can restrict the water flow. If the ice maker does not fill completely with water the motor can overheat when it begins to cycle.

Cold

The colder the freezer, the faster ice is produced. If the freezer temperature is 10 degrees or higher it is not cold enough for the ice maker to work properly or at all.

No Ice

When the ice maker stops working, turn the water going to the refrigerator and the ice maker off immediately. If the unit continues to run without producing ice, the water could be diverted and leaking on the floor and possibly causing water damage.
