How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. Turn off the breaker and leave it off until the fault is identified.
- Visual inspection: With power off, open indoor and outdoor electrical covers and look for burnt wires, melted insulation, or water inside.
- Dry moisture: If water is present, dry the area thoroughly and identify the source of ingress (failed grommets, covers).
- Isolate components: A technician can disconnect compressor or fan motors one at a time to identify the faulty component.
- Check breaker rating: Ensure the breaker size matches SMEG installation specifications; an undersized breaker can nuisance-trip.
Compressor or motor replacement and insulation resistance testing must be done by a qualified technician.
