How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. This is a fire hazard. Turn off the breaker and investigate.
Steps to check:
- Visual inspection: With power off, inspect wiring for obvious shorts, burned insulation, or loose connections.
- Isolate components: A technician can disconnect blower and inducer motors one at a time to determine which is causing the overload.
Because breaker tripping indicates a potentially serious electrical fault, contact a qualified technician for further diagnosis and repair.
