DOOR DISPENSER
13.1 Operation
SECTION 13
WATER DISPENSER (OPTIONAL)
The water dispenser works much like the ice dispenser.
To request water at the door, simply press the lever. This
will activate a switch which turns on an electric water valve
at the back of the refrigerator. Water will ow through a
separate tube right into the glass.
LOCK OUT FEATURE
The ice dispensing system can be locked out to prevent
unwanted use.
Lock out•
To lock out, press the “Lock” pad for (3-5) seconds
until the RED light above the Padlock comes on.
Unlock•
To unlock, press the “Lock” pad for (3-5) seconds un-
til the RED light above the Padlock goes out.
The light can be turned on and off by pressing the “Light”
touch pad. The light will illuminate the dispenser area.
The light will also turn on automatically when ice or water
is dispensed.

AUTOMATIC POWER SUPPLY SWITCH OFF
For safety reasons, when opening the freezer door, the
ice/water dispenser and ice maker system will automati-
cally shut off. Closing the freezer door automatically re-
sumes operation of ice/water dispensing and ice maker
operation.
ICE DISPENSER (OPTIONAL)
For a refrigerator to provide ice through the door, the ice
maker rst dumps the ice it produces into a large bin. To
request ice at the door, select Cube or Crush and then
press the lever. This will activate a switch which turns on
a motor that rotates the auger. When the auger rotates,
it pushes ice out of the bin, through a chute right into the
glass. To stop dispensing, pull the glass away from dis-
pensing arm before the glass is full. Allow the ice chute to
clear before removing the glass.
13.2 Auger
When the paddle on the door dispenser is depressed call-
ing for ice, a switch will be closed sending AC voltage
via the yellow wire to the interface module. This contact
on the interface module is a bridged set of terminals that
internally send the AC voltage to the auger motor. As the
auger motor rotates, this pushes the ice forward in the ice
bin and down through a chute to the door dispenser. To
check the motor, disconnect the 120 volt AC supply to the
interface module. Measure the resistance between the
wires on terminals (J6) and (J3) of the interface module.
The resistance should be 4.0 Ohms +/- 10%. The resis-
tance can also be checked directly at the motor assembly.
This will require removal of the plate along the back wall
of the freezer just behind the ice bin.
This is an energized circuit. Shock can occur
if not tested properly. Testing is to be done
by a qualied service technician.
