SYSTEM DIAGNOSTIC MODE
Activate:
Is resistance across all winding
pairs equal?
no
Check voltage supply.
Check and repair power
cord harness wiring and
connections.
Remove inverter box from the
compressor and check resistance
across compressor winding pairs as
shown.
Check at Main Control Board
(BLK/WHT and RED/BLK wires)
Is Main Control Board sending
10-15 VAC and 1-5 VDC to
Inverter Board?
yes
P-2
Identify and repair damaged wires or
poor connections between Main Control
Board and Inverter Board.
yes
Check connections from Inverter
Board to Compressor
Are connections from Inverter
Board to Compressor intact?
no
Replace Compressor and
Inverter Board.
→
→
no
no
Identify and repair damaged
wires or poor connections
between Inverter Board and
Compressor.
yes
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.
Replace Inverter Board
IMPORTANT SAFETY NOTE
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.
IMPORTANT
CAUTION
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.
Water Fill
Adjustment
If any green grounding wires are removed during servicing, they must be returned to their original position and
properly secured.
Motor
Gear
TU
(Where Applicable)
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.
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.
