Location

The auger motors are located at the upper rear of the dispenser chassis inside the auger motor covers.

Test Procedures

1.Remove the hopper from the same side as the motor to be tested.

2.Turn “ON” the appropriate auger switch.

3.Nudge the auger to start it turning.

If the auger doesn’t turn, replace the motor.

If auger starts to turn, replace the start capacitor.

WARNING: The compressor start capacitor must be properly discharged before removing. This is most commonly done on low voltage capacitors by shorting across the terminals with a screwdriver.

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 securing the auger motor run capacitor. Set capacitor aside with wires at- tached.

4.Disconnect the auger motor terminal from the terminal on the main wiring harness.

5.Remove the three remaining #8 locking screws secur- ing 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 assembly.

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 remaining #8 locking screw.

9.Connect the auger motor terminal to the terminal on the main wiring harness.

10.Refer to Fig. 2 when reconnecting the wires.
