FREEZER ICE MAKER INFORMATION

Test Cycling: Remove cover by inserting screwdriver in notch at bottom and prying cover from hous-

ing. 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.

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.

(Where Applicable)

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
