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.

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.

FREEZER ICE MAKER INFORMATION

(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.
