Some time during the second revolu-
tion the mold heater resets the ther-
mostat. at this time, the mold heater
is de-energized. If the storage bin is
full, the shut-off arm will remain in a
raised position.
At the end of the rst revolution
the timing cam opens the holding
switch. However, since the thermo-
stat is still closed a second revolu-
tion begins.
Once again after a few degrees of
rotation the timing cam closes the
holding switch providing a circuit to
the motor that will assure completion
of this revolution. The mold heater
remains energized. The shut-off arm
will raise and lower again operating
its switch. The ice that was ejected
during the rst revolution is dumped
into the storage bin.
Near the completion of the rst rev-
olution, the timing cam closes the
water valve switch. However since
the thermostat is still closed the
mold heater circuit is energized.
Current will not pass through
the water valve solenoid and its
switch. (Electrical current follows
the path of least resistance.)
