Possible Causes

How to Fix / Troubleshooting
Safety: Use caution when touching the motor; surfaces may be very hot.
- Improve ventilation: Remove obstructions around the Onga motor and consider adding shade without blocking airflow.
- Check system head: Ensure the filter is clean and valves are fully open to reduce load.
- Verify impeller: Confirm the impeller matches the motor rating; an oversized impeller can overload the motor.
Monitor temperature after changes. If the motor remains excessively hot, consult a technician to measure current draw and confirm suitability.
