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.

CAUTION

All electrical parts and wiring must be shielded from torch ame. DO NOT allow torch to touch insulation; it will char at 200°F and ash ignite (burn) at 500°F. Excessive heat will distort the

plastic liner.

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 ll adjustment screw will change the ll time. One full turn is equal to 20cc (.68 oz.). The correct ll is 102 to 130cc (3.4 to 4.3 oz.). When a water valve is replaced, the ll volume must be checked.
