IMPORTANT SAFETY NOTE
FREEZER ICE MAKER INFORMATION
(Where Applicable)
The information provided herein is designed to assist qualified repair personnel only. Untrained persons
should not attempt to make repairs due to the possibility of electrical shock. Disconnect power cord before
servicing this appliance.
Water Fill
Adjustment
Motor
Gear
TU
R
N
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.
Replace Inverter Board
Check resistance between terminals 1 and
2, 2 and 3, 3 and 1.
If all resistances are equal,
compressor is operative.
Identify and repair damaged wires or
poor connections between Main Control
Board and Inverter Board.
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.
Identify and repair damaged
wires or poor connections
between Inverter Board and
Compressor.
yes
yes
All electrical parts and wiring must be shielded from torch flame. DO NOT allow torch
to touch insulation; it will char at 200°F and flash ignite (burn) at 500°F. Excessive
heat will distort the plastic liner.
