FREEZER ICE MAKER INFORMATION
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.

IMPORTANT SAFETY NOTE
The information provided herein is designed to assist qualied repair personnel only. Untrained persons should
not attempt to make repairs due to the possibility of electrical shock. Disconnect power cord before servicing
this appliance.
IMPORTANT
If any green grounding wires are removed during servicing, they must be returned to their original position and
properly secured.
VCC COMPRESSOR MOTOR RESISTANCE CHECK
Check resistance between terminals 1 and
2, 2 and 3, 3 and 1.
If all resistances are equal,
compressor is operative.
