How to Fix / Troubleshooting
Safety: Repeated breaker tripping indicates a serious fault. Turn OFF the breaker and do not reset repeatedly.
- Visual inspection: With power OFF, open the condenser panel and inspect for burnt wires, melted insulation, or signs of arcing.
- Isolate components: A technician can disconnect the compressor and fan motor leads and test each component’s resistance to ground to identify shorts.
- Check breaker rating: Verify the breaker size matches the Coleman unit’s MOCP rating on the nameplate.
- Replace failed components: Replace any shorted motors or compressors with OEM or approved equivalents.
Warning: This level of diagnosis typically requires a professional with appropriate test equipment.
