securing the auger motor mounting bracket to
cooling drum mounting bracket.
6. Remove motor with mounting bracket, drip tray,
split pin and torsion spring bearing as an assem-
bly.
NOTE: When removing or installing the motor be sure
the split pin in the motor shaft is turned to a position
that will clear the torque sensor circuit board.
7. Install new motor with mounting bracket, drip
tray, split pin and torsion spring bearing using
three #8 locking screws onto the cooling drum
bracket.
8. Install the auger motor capacitor on the lower right
side of the auger mounting bracket, using the

Location
The auger motors are located at the upper rear of
the dispenser chassis inside the auger motor covers.
Test Procedures
1. Disconnect the dispenser from the power source.
2. Disconnect the wires from the motor to be tested.
3. With a voltmeter, check the voltage across the
white/brown wire for the left motor, the white/blue
wire for the right motor, or the grey wire for the
center motor and the white/black wire. Place the
appropriate auger switch in the “-” (“ON”) posi-
tion. Connect the dispenser to the power supply.
The indication must be:
a) 120 volts ac for 120 volt models.
b) 230 volts ac for 230 volt models.
4. Disconnect the dispenser from the power supply.
If voltage is present as described, replace the motor.
If voltage is not present as described, refer to the
Wiring Diagram and check the dispenser wiring har-
ness.
Removal and Replacement
1. Remove the two #8 locking screws securing the
auger motor cover to the cooling drum mount
assembly.
2. Remove the cover and set aside for reassembly.
3. Remove the #8 locking screw on the lower right
side of the auger motor mounting bracket secur-
ing the auger motor run capacitor. Set capacitor
