Questions and Answers

    Why is my Hayward Controller motor so hot?
    • J
      Jennifer TaylorAug 3, 2025
      If your Hayward Controller actuator motor is extremely hot, it might be due to control “noise” or an excessive duty cycle. Check for stray voltage fluctuations on the incoming control signals. Remember, on/off line voltage actuators have a maximum 25% duty cycle, while low voltage models have a 75% duty cycle. Also, check for parallel wiring of multiple on/off actuators by reviewing the site as-built wiring diagrams to verify.

    Why Hayward Controller actuator doesn't stop at correct position?
    • K
      Katherine BrownAug 18, 2025
      If the Hayward Controller actuator doesn't stop at the correct position, it may be out of quadrant. Use the manual override to rotate the actuator back into its correct quadrant of operation. Also, the travel cams and/or mechanical stops may not be positioned correctly.
