Variable Capacity Compressor (VCC) Diagnostics (select models)
If test 38 fails, diagnose as follows:
Replace Inverter Board
→ 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?
→ 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?
no
→ 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?
• Check voltage supply.
• Check and repair power
cord harness wiring and
connections.
no
Identify and repair damaged wires or
poor connections between Main Control
Board and Inverter Board.
yes
→ Remove inverter box from the
compressor and check resistance
across compressor winding pairs as
shown.
Is resistance across all winding
pairs equal?
Replace Compressor and
Inverter Board.
no
→ Check connections from Inverter
Board to Compressor
Are connections from Inverter
Board to Compressor intact?
yes
Identify and repair damaged
wires or poor connections
between Inverter Board and
Compressor.
no
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 Main Control Board.
no
yes yes
yes
