How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripped breaker. Turn it off and leave it off until the cause is found.
- Visual inspection: With power off, inspect wiring in the outdoor unit for burns or shorts to the cabinet.
- Isolate components: A technician can disconnect the compressor and fan separately to determine which is causing the trip.
- Breaker check: Have an electrician verify the breaker size matches the Trane unit nameplate and that the breaker itself is not faulty.
Because of shock and fire risk, breaker-tripping issues should be handled by a qualified technician.
