ICE MAKER INFORMATIONTest Cycling

Press the momentary contact on the ON/OFF switch for approximately 15 seconds. Ice maker will continue to complete the cycle.

Water Fill Volume

The water fill can be adjusted without removing the ice maker cover. To adjust the fill size, remove the small round plug next to the On/Off Switch. Insert a #2 Phillips screwdriver into the hole about an inch or until it engages the Water Fill Adjustment Screw. Turn the screw clockwise to reduce the fill size; turn the screw counterclockwise to increase the fill size. One turn equals approx 20cc (0.68 oz). The correct fill is 85 to 95cc (2.75 to 3.25 oz). When a water valve is replaced, check the fill volume.
