Possible Causes
Blocked cooling vents, Pump running with restricted flow, High ambient temperature, Failing motor windings
How to Fix / Troubleshooting
Safety first: Disconnect power and allow the motor to cool before touching it.
- Clear vents: Inspect the motor housing for dust, spider webs, or debris blocking the cooling slots. Clean with a brush or compressed air.
- Check water flow: Ensure the filter is clean and valves are fully open so the pump is not working against a heavy restriction.
- Improve environment: Move the pump to a shaded, well-ventilated area if it is in direct sun or enclosed.
- Monitor runtime: After cooling and cleaning, run the pump and monitor temperature. If it overheats quickly again, the motor insulation may be breaking down and the pump motor assembly should be replaced.
