General Information
End of Ice making Cycle
• The water valve solenoid switch is tripped by the
timing cam back to "normally open" ending the
water fill.
• The timing cam trips the holding switch to "normally
close," which ends the second revolution.
• The thermostat is still open, so it does not start the
drive motor.
• If the shut-off arm has come to rest on top of the
ice in the storage bin (as illustrated), the shut-off
switch remains in the "normally closed" position.
This interrupts power from reaching the thermostat,
until sufficient ice has been removed from the stor-
age bin allowing the shut-off arm to lower.
NOTE: To allow ice to freeze fully and reduce effects of
low water pressure, the electronic control system dis-
ables the icemaker system for 45 minutes after each ice
harvest.
MANUALLY STOPPING ICE PRODUCTION
Ice production can be manually stopped two ways:
1. Press the "ICE MAKER" key on the control panel so
that the ice cube icon is not displayed on the LCD.
2. Position the ice-level/shut-off arm in the up/OFF
position (See Figure 6-12).
