Water Fill Adjustment

Turning the water level adjustment screw will move
the contact in its relationship with the contact ring seg-
ment. This causes the contact to vary time the water
valve is energized, since the contact ring is tapered at
the end of the fill time.
Turning screw clockwise decreases fill; counterclock-
wise increase fill amount.
1/2 turn equals 20 cc or 1.2 seconds
Full turn equals 40 cc or 2.4 seconds
Maximum adjustment is one full turn either direction.
Additional rotation could damage module.
If water valve adjustment screw falls out, just put it
back in and align the hole in the hole as shown.
When small hole is centered in l arger hole, the water
fill adjustment is for 7.5 seconds fill time (normal).

Water Problems

Water quality can cause ice makers to fail, or produce
unacceptable cubes. If mineral content or sand is a
problem, the screen in the fill valve can restrict, or a
particle of sand can keep the valve from seating prop-
erly. Results will be small crescents (or no ice) or
flooding of the ice container if the water valve does not
close. Where required, install the ASAP grandular ac-
tivated carbon, odor, tastes, and sediment filter, part
number R0183114.
Mineral contact can also lime up the mold, causing
wicking of water over the mold and poor cube release.
Silicone is applied at the upper edges, around fill cup
and stripper.

Temperature Problems

Temperatures in freezer section which average above
the normal 0° ±2°F (-18°±1°C) will slow production of
ice. Complaints of inadequate crescent production
may be corrected by simply setting the freezer to a
colder temperature. The thermostat cycling tempera-
ture in the 1-revolution ice maker is 17° ± 3°F (-8°
±1°C). Obviously, the ice will be well frozen when
these temperatures are achieved but cycling time will
be slowed if freezer temperature is not cold enough to
achieve these mode temperatures easily.
NOTE: Only the thermostat, mold, with heater and
wiring harness, are replaceable. Any other failure (in-
cluding the motor) requires replacement of the module
assembly. The service replaceable mold assembly
comes with a new mold heater installed.
External plastic parts are also replaceable.
A failed mold heater requires complete replacement of
the mold and mold heater assembly.

Servicing Thermostat

The thermostat can be removed and replaced having
been diagnosed as inoperative. Remove control box
from mold by taking out two phillips screws.

Adjustment
Area
Pull (front of Black Housing) free of the mold, and see
the thermostat on mold side.
Using needle nose pliers, grasp one of the thermostat
clips and pull out. Press in new thermostat, making
sure pins are properly indexed. Using this procedure,
it is not necessary to remove the electrical assembly.
If replacing the module, transfer the clips to the new
mold support. (Use new thermal bonding material.)
