Locate the ice and water dispenser control panel positioned on the exterior face of the front door on the freezer compartment; it's just above the rectangular opening that releases the water and ice.
Press down the button labeled "Lock" one time to engage the "Lock" feature on the control panel unit and disengage the electronic eye sensor for the ice release and the water dispenser.
Depress the "Unlock" pad once to re-engage the electronic eye sensor and restore the normal ice and water dispenser operations.
Depress the pad labeled "Lock Out" once, on models with this alternate control panel keypad design. Re-enable the sensor and dispensing capabilities by pressing and then holding the "Lock Out" key down for two to three beats before releasing it to the neutral position.
