INSTALLING WATER SUPPLY LINE TO
ICE MAKER
Supply line installation must comply with all applicable
plumbing codes. Refer to the
Ice Maker Installation
Instructions.
The ¼” tubing, and any other plumbing materials
required, should be obtained locally.
The Ice Maker should be connected to a frequently used
cold water line to ensure a fresh water supply.
NOTE: A vertical cold water line should be selected
for the water supply. If a vertical line is not available,
a horizontal line may be used, providing the
connection is on the side or top of the pipe, but
not
on the bottom . Scale and foreign material in the
pipe could cause stoppage of water flow if the
connection is on the bottom.
Be sure to leak test all connections after the water
supply has been turned on.
TEST CYCLING ICE MAKER (See Ice Maker Testing
Procedures on pages 59-68).
It may be necessary, on occasion, to test-cycle an Ice
Maker to check its operation. This can be done on the
repair bench or while mounted in the Refrigerator.
If the Ice Maker is in an operating refrigerator, take
precautions against the formation of condensate by
allowing the cold, metal components to warm up before
removing the front cover. This can be expedited by
cycling the assembly with the cover in place and the
water supply valve closed.
To manually cycle the Ice Maker, slowly turn the Ejector
blades clockwise until the Hold Switch circuit to the
Motor is completed. When the Motor starts, all
components except the Ice Maker Thermostat should
perform normally. Once the Ice Maker completes its
cycle, remove the front Cover; see instructions for
replacing the front Cover in
“To Replace Front Cover”
on this page.
If further test cycling is necessary, place screwdriver
blade in slot located in the Motor Drive Gear and turn
counterclockwise until the Hold Switch circuit to the
Motor is completed.
WATER VALVE SWITCH – WATER FILL VOLUME
The amount of water fill is directly proportional to the
length of time terminals “C-NC” of the Water Fill Switch
are closed. Closing occurs when the switch plunger
drops into a cavity formed in the Cam.
Different water valves have different flow rates. For this
reason, anytime a Water Valve is replaced, the Water
Fill Switch must be adjusted.
The correct water fill volume is 95-105 cc. To measure
the fill volume, test-cycle the Ice Maker and collect the
water. Measure in a container calibrated in cubic
centimeters (cc) or ounces.
The fill volume is adjusted by increasing or decreasing
the length of time the Water Fill Switch remains closed.
To adjust the Water Fill Switch, first determine how
much water is needed. The adjusting screw is
calibrated so that one complete revolution changes the
water fill about 18 cubic centimeters. Turning the screw
clockwise decreases the fill, while turning counter-
clockwise increases the fill.
EXAMPLE: An Ice Maker is test-cycled and the water fill
sample is 158 cubic centimeters. Subtracting 145 cc
from 158, the adjustment needed is 13 cc. Since one
turn of the adjusting screw changes the fill 18 cc, ¾ of
a turn clockwise would reduce the fill about 13 cc, the
desired amount. (This example is for manual models
only.)
PARTS REPLACEMENT
Disconnect electrical supply to refrigerator. If the
Refrigerator is operating and cold, allow the Ice Maker to
warm up to room temperature before removing the front
cover. This prevents moisture from condensing on the
metal components.
To Replace Front Cover (See Figure F4)
1. Ensure that Ice Maker is at room temperature before
removing Cover.
2. Place straight blade of screwdriver in slot at bottom
of Mold Support and pry Cover loose.
NOTE: Ensure that the retaining tabs inside the
Cover are located on the top and bottom when
installing the Cover.
3. Snap Cover in place.
