voltage is within the proper range, check for continuity through the protector.

5.Check for overloading from other appliances on the same circuit as the motor.

6.Inspect the motor windings for continuity.

7.If voltage is proper at terminals and the motor is cold, remove the motor and take it to a A.O. Smith Authorized Service Center.

MOTOR FAILS TO START (hums, tries to start, blows fuse or trips breaker)

1.Check the motor connections after TURNING OFF THE POWER.

2.Check the voltage (see #5 above) as the motor tries to start. If voltage is too low, look for undersized wiring, an overloaded circuit or a burned start winding.

3.If the voltage is proper at terminals and motor is hot, TURN OFF THE POWER and allow the motor to cool to ambient temperature then reapply power.

If the motor starts then shuts down, you have an overload. Check the amp draw at the motor terminal and compare it to amps shown on the motor nameplate. If the amp draw is greater then the nameplate current, check for impeller rub in the pump or a tight seal. If this fails to correct the problem, remove the motor from pump and take to a A.O. Smith Authorized Service Center.

4.Check the capacitor but first — TURN OFF THE POWER. After removing the capacitor from the motor, discharge it by laying an insulated screwdriver across its terminals. Check the
