FREEZER ICE MAKER INFORMATION
(Where Applicable)
Test Cycling: Remove cover by inserting screwdriver in notch at bottom 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 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.
