MOTOR (Models LPG & FPG)

FIG. 9 MOTOR

P1022

 

Location:

The motor is located inside the hopper assembly. Test Procedures:

1.Disconnect grinder from the power supply.

2.On Model LPG-2E, disconnect the black wire and the white wire to the motor from the main wiring harness, the red wire to the circuit breaker and the red wire to the Off/On/Start switch. On Model LPG disconnect the motor wiring harness from the main wiring harness.

3.Connect the leads of an ohm meter to the red wires from the motor.

If continuity is present the overload is good.

If continuity is not present the overload will not reset, replace the motor.

4.Set an ohm meter to read at least 20 ohms. Connect the leads from the ohm meter to the black wire and the white from the motor. The ohm reading should be approximately 18 ohms. Using the bean agitator slowly rotate the motor shaft in approximately 1/8

turn steps through one full rotation. If ohm readings are consistent motor windings are good. If readings vary more than ±1 ohm, replace motor.

NOTE: Clean all grind burrs and mounting surfaces before reassembly.

Removal and Replacement:

1.On Model LPG-2E, disconnect the black wire and the white wire to the motor from the main wiring harness, the red wire to the circuit breaker and the red wire to the Off/On/Start switch. On Model LPG disconnect the motor wiring harness from the main wiring harness.

2.On Model LPG-2E, disconnect the red wire from the left and right solenoid, the orange wire from the left solenoid and the violet wire from the right solenoid.
