Troubleshooting:

Motor will not run:

1. Check incoming power to control cabinet.
2. Check for tripped manual motor starter (overload) in control cabinet.

(Refer to Motor Overload service section for the proper setting)

3. Check power at motor contactor.

Motor runs hot and trips motor starter overload:

1. Check for proper voltage between L1-L2, L2-L3, L1-L3 for 3 phase.
2. Check FLA on motor leads L1, L2 and L3 using amp tester.

(Motor full load amp (FLA) ratings are stamped on motor nameplate).

Motor Replacement:

1. Disconnect the power to the machine.
2. Disconnect the wires at the motor junction box.
3. Make note of the motor connections in order to phase the replacement correctly.
4. Install the new motor and check for proper rotation.
5. Proper shaft rotation is clockwise looking at the rear of the motor.
6. Motor rotation can be reversed by switching L1 and L2 on 3 phase motors. Single phase

motor rotation cannot be reversed
