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)
CAUTION
FREEZER ICE MAKER INFORMATION
Water Fill
Adjustment
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.
→
Check at Main Control Board
(BLK/WHT and RED/BLK wires)
yes
Identify and repair damaged wires or
poor connections between Main Control
Board and Inverter Board.

Remove inverter box from the
compressor and check resistance
across compressor winding pairs as
shown.
Is resistance across all winding
pairs equal?
→
yes
Check connections from Inverter
Board to Compressor
Are connections from Inverter
Board to Compressor intact?
no
Replace Compressor and
Inverter Board.
Is Main Control Board sending
10-15 VAC and 1-5 VDC to
Inverter Board?
N
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.
→
yes
no
Check voltage supply.
Check and repair power
cord harness wiring and
connections.
(Where Applicable)
Check at Inverter Board on
Compressor
(BLK and RED wires)
Is Inverter Board receiving 10-15
VAC and 1-5 VDC from Main
Control Board?
no
•
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.
→
yes
Is Inverter Board receiving 115 VAC
from power supply?
