Ice Maker
If water valve adjustment screw fall out, put screw in
hole and align as shown below.
When small hole is centered in large hole, water fill
adjustment is 7.5 seconds (normal fill time).
Water Problems
Poor water quality can cause ice maker to fail or
produce unacceptable cubes. Mineral content or sand
can restrict screen in water fill valve or particle of
sand can keep valve from seating properly.
If water valve does not close, the following could
occur
•
no ice production
•
small or hollow ice cubes
•
flooding of ice container
Install water filter to eliminate bad taste, odor, and
visible contaminates.
Mineral contact can cause lime build up in mold,
Wicking of water over mold and poor cube release
can occur. Silicone is applied at upper edges around
fill cup and stripper.
Temperature Problems
Freezer temperatures above normal 0
° ±
2
°
F (-18
°±
1
°
C) will slow down ice production. Increase ice
production by setting freezer to colder setting.
Thermostat cycling temperature (1 revolution ice
maker) is 17
° ±
3
°
F (-8
° ±
1
°
C). Ice will freeze
when these temperatures are achieved. Cycling time
will be slower if freezer temperature is not cold
enough to achieve mode temperatures easily.
Thermostat, mold heater, and wiring harness are
replaceable. Any other failure, including motor,
requires replacement of module assembly.
Replacement mold assembly comes with new mold
heater installed.
Thermostat
1. Remove control box from mold be removing
screws.
2. Pull front of black housing free of mold.
Thermostat is on mold side.
3. Grasp 1 thermostat clip and pull out.
4. Press in new thermostat. Verify pins are
properly indexed. Electrical assembly does not
need to be removed.
If replacing module, transfer clips to new mold
support. Use new thermal bonding material.
Wiring Harness
Remove wiring harness by pressing retaining tab
and pulling forward.
