FREEZER ICE MAKER INFORMATION
(Where Applicable)
Test Cycling: Remove cover by inserting screwdriver in notch at bottom and pry-
ing 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 fill adjustment screw will change the fill time.
One full turn is equal to 20cc (.68 oz.). The correct fill is 102 to 130cc (3.4 to
4.3 oz.). When a water valve is replaced, the fill volume must be checked.
