How to Fix / Troubleshooting
Safety: Do not repeatedly reset a breaker that trips immediately; this is a fire hazard. Unplug the unit before inspection.
- Check circuit rating: Ensure the air conditioner is on a circuit with adequate amperage as specified on the nameplate.
- Inspect cord and plug: Look for cuts, burns, or melted areas. Replace the cord if damaged.
- Internal inspection: Remove panels and inspect wiring for signs of chafing, melted insulation, or contact with sharp metal edges. Repair or replace damaged wires.
- Component isolation (technician): A professional can disconnect the compressor and motors to determine which component is causing the overcurrent and replace it.
