Possible Causes
Shorted blower motor, Shorted igniter, Damaged wiring harness, Failed control board component
How to Fix / Troubleshooting
Safety first: Turn OFF power at the breaker. Do not repeatedly reset a tripping breaker without finding the cause.
- Inspect wiring: Look for melted insulation, burnt connectors, or wires rubbing on sharp metal edges inside the heater.
- Check motors and igniter: Disconnect the blower motor and igniter one at a time (with power OFF), then restore power and see if the breaker still trips. This can help isolate the faulty component.
- Examine control board: Look for burnt traces or components on the board. A burnt smell often indicates board failure.
- Replace failed parts: Replace any shorted motor, igniter, or control board with Poolworld-approved components.
Warning: Electrical shorts can cause fire. If you are not comfortable troubleshooting live circuits, contact a qualified technician.
