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)
→
yes
Check at Inverter Board on
Compressor
(BLK and RED wires)
→
yes
Is Inverter Board receiving 10-15
VAC and 1-5 VDC from Main
Control Board?
Is Inverter Board receiving 115 VAC
from power supply?
no
FREEZER ICE MAKER INFORMATION
(Where Applicable)
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 voltage supply.
Check and repair power
cord harness wiring and
connections.
Replace Compressor and
Inverter Board.
→
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?

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.
Remove inverter box from the

across compressor winding pairs as
shown.
Is resistance across all winding
pairs equal?
no

If all resistances are equal,
compressor is operative.
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.
Replace Inverter Board
If any green grounding wires are removed during servicing, they must be returned to their original position and
