How to Fix / Troubleshooting
Safety: Repeated breaker tripping indicates a serious electrical fault. Do not keep resetting the breaker.
- Visual inspection: With power off, inspect wiring inside the Crown boiler for burned insulation, loose wires, or signs of arcing.
- Isolate components: A technician can disconnect loads (pump, fan) one at a time to identify the faulty component.
