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?

→

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.

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?

Replace Compressor and 

Inverter Board.

→

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.

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.

Notes:
• Always check for pin back-outs, pinched or damaged wires before replacing 

components.

• Determine whether failure is caused by the component, main control board or 

wiring. 

• Refer to Service Manual for additional information.

Test Cycling: Remove cover by inserting screwdriver in notch at  bot-
tom 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.
