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 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 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.

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?
no
• Check voltage supply.
• Check and repair power
