Why is my Hayward Controller motor so hot?
- JJennifer 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.
