AUGER MOTOR CAPACITOR

ULTRA-2 shown
FIG. 3 AUGER MOTOR CAPACITORS	P1341

Location:

The auger motor capacitor(s) are located on the lower right side of the auger motor mounting bracket inside the auger motor cover(s).

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 assy.

2.Remove the cover and set aside for reassembly.

3.Disconnect the wires from the auger motor capacitor terminals.

4.Remove the #8 locking screw on the lower right side of the auger motor mounting bracket securing the auger motor capacitor.

5.Install a new capacitor on the lower right side of the auger mounting bracket and secure with a #8 locking screw.

6.Reconnect the wires to the capacitor terminals.

7.Refer to Fig. 4 when reconnecting the wires.
