AO Smith pool pump motor cycles on and off repeatedly during operation without tripping the breaker.

Safety First: Disconnect power before inspection.

• Improve cooling: Clear debris from motor vents and ensure adequate airflow around the AO Smith motor.
• Check load: Verify that the pump is not dead-headed and that filter pressure is within normal range.
• Measure current: Have a technician measure running amps. If near or above nameplate rating, reduce system head or consider a lower HP motor.
• Replace motor if protector is weak: If cycling occurs even at normal load and temperature, the internal thermal protector may be failing and the motor should be replaced.
