How to Fix / Troubleshooting
Safety: This is a potentially serious electrical issue. Unplug the unit and do not reset the breaker repeatedly.
- Inspect cord and plug: Look for visible damage. Replace the power cord if any defects are found.
- Visual internal check: With the unit unplugged, inspect wiring for burn marks, melted insulation, or wires touching sharp metal edges.
- Isolate components (advanced): A technician can disconnect the compressor and fan motors one at a time to identify which component causes the breaker to trip when energized.
- Replace failed component: Replace the compressor, fan motor, or main control PCB as indicated by testing. Due to high voltage and refrigerant, this is typically professional work.
