FREEZER ICE MAKER INFORMATION
(Where Applicable)
Test Cycling: Remove cover by inserting screwdriver in notch at bottom and pry-
ing 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.
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.
IMPORTANT SAFETY NOTE
The information provided herein is designed to assist qualied 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.
IMPORTANT
If any green grounding wires are removed during servicing, they must be returned to their original position
and properly secured.

LED POWER
BOARD
Variable Capacity Compressor (VCC) Diagnostics (select models)
If test 38 fails, diagnose as follows:
→ Check at the connector from the power cord
harness into the inverter board, located in
the machine compartment.
(PUR and WHT wires)
Is Inverter Board receiving 115 VAC
from power supply?
no
• Check voltage supply.
• Check and repair power
cord harness wiring and
connections.
yes
→ Check at Inverter Board on
→ Check at Main Control Board
Identify and repair damaged wires or
poor connections between Main Control
Board and Inverter Board.
Compressor
(BLK and RED wires)
Is Inverter Board receiving 10-15
VAC and 1-5 VDC from Main
Control Board?
(BLK/WHT and RED/BLK wires)
Is Main Control Board sending
10-15 VAC and 1-5 VDC to
Inverter Board?
no
yes
→ Remove inverter box from the
compressor and check resistance
across compressor winding pairs as
yes yes
shown.
Is resistance across all winding
pairs equal?
no
Replace Compressor and
Inverter Board.
no
Replace Main Control Board.
VCC Resistance Check
Check resistance between terminals 1 and
2, 2 and 3, 3 and 1.
If all resistances are equal,
compressor is operative.
→ Check connections from Inverter
Board to Compressor
Are connections from Inverter
Board to Compressor intact?
Identify and repair damaged
wires or poor connections
between Inverter Board and
Compressor.
no
Replace Inverter Board
yes
