End of Ice making Cycle (See Figure 6-11)
• 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.
Figure 6-12. Stopping Icemaker
MANUALLY STOPPING ICE PRODUCTION
Ice production can be manually stopped four ways:
1. Press the ICE ON/OFF key on the control panel so
that “ICE” is not displayed on the LCD.
2. In model 632 and 642, trip the icemaker switch
above the ice bucket to the OFF position.
3. In models 601F, 611, 650, 680 and 690, remove the
ice bucket so that the icemaker switch at the back
of the freezer is not being depressed. Also, make
sure no food product is coming in contact with the
icemaker switch.
4. In models 611, 650, 680 and 690, lift the ice level
arm up to lock it in the OFF position (See Figure 6-
12).
