FREEZER ICE MAKER INFORMATION

(Where Applicable)

Test Cycling: Remove cover by inserting screwdriver in notch at bot-

tom and prying cover from housing. Use screwdriver to rotate motor

gear counterclockwise until holding switch circuit is completed. All

components of ice maker should function to complete the cycle.

Water Fill Volume: The water ll adjustment screw will change

the ll time. One full turn is equal to 20cc (.68 oz.). The correct ll is

102 to 130cc (3.4 to 4.3 oz.). When a water valve is replaced, the ll

volume must be checked.
