When the glass is pulled away from the actua-
tor the Actuator switch will open the signal to the
lower control board. The lower control board will
send a 12 VDC signal to the relay board for 10 mill-
a-seconds to unlock the door linkage allowing the
ice door spring to close the ice door. (See Figure
11) This will close the contacts on the ice door
switch telling the lower control board the door is
closed. If the switch contacts do not close the
lower control board will send a 12 VDC signal to
the relay board for 10 mill-a-seconds again to un-
lock the door linkage allowing the ice door spring
to close the ice door. The lower control board will
continue to do this until the ice door is closed.
