Possible Causes

Shorted compressor, shorted fan motor, damaged power cord, water ingress into electrical components, faulty main PCB

How to Fix / Troubleshooting

Critical safety: Repeated breaker tripping indicates a potentially dangerous fault. Do not repeatedly reset without inspection.

Steps:

  • Visual inspection: Unplug the unit and inspect the power cord, plug, and visible wiring for burns, cuts, or melted insulation.
  • Moisture check: Look for signs of water inside the control compartment or near the PCB. Dry thoroughly and correct any leaks.
  • Isolate cause (advanced): A technician can disconnect compressor and fan motors one at a time to identify which component causes tripping when reconnected.

Because of shock and fire risk, breaker-tripping faults should be handled by a qualified technician. Do not bypass protective devices.
