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. Contact TID before replacing main control board.

• Refer to Service Manual for additional information.

Failure

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)

Is Inverter Board receiving 115 VAC from power supply?

• Check voltage supply.

• Check and repair power

cord harness wiring and connections.

→ 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?

→ 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?

yes

Identify and repair damaged wires or

poor connections between Main Control Board and Inverter Board.

FREEZER ICE MAKER INFORMATION

(Where Applicable)

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.

Display Activate/Deactivate

(press for up to 10 sec. simultaneously)

٨ and ٧/ + to deactivate

play, all UI LEDs on.

→ Remove inverter box from the

compressor and check resistance across compressor winding pairs as

yes yes

shown.

Is resistance across all winding pairs equal?

Replace Compressor and Inverter Board.

Replace Main Control Board.

VCC Resistance Check

Check resistance between terminals 1 and 2, 2 and 3, 3 and 1.

If all resistances are equal,

compressor is operative.

→ 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.

Replace Inverter Board

yes
