How to Fix / Troubleshooting
Safety: This involves high voltage. If you are not experienced, contact a licensed electrician or technician.
Steps:
- Dedicated circuit: Confirm the AC is on a dedicated circuit of the correct amperage as specified on the rating plate.
- Inspect cord and plug: Look for damage or burn marks. Test the LCDI/GFCI plug by pressing RESET. Replace the power cord assembly if damaged.
- Visual internal check: With power disconnected, remove the front and cabinet. Look for burnt wires, melted insulation, or arcing marks, especially near the compressor, capacitor, and control board.
- Component isolation: A technician can disconnect the compressor and fan motors one at a time to identify which component is causing the breaker to trip.
