Possible Causes

Shorted or seized compressor in Camry outdoor unit, Faulty inverter power module (IPM) on outdoor PCB, Incorrect supply voltage or loose power connections, Blocked condenser coil causing high current draw

How to Fix / Troubleshooting

Safety first: Isolate power at the main breaker. Overcurrent faults involve high voltages and should be handled by qualified personnel.

  • 1. Visual inspection: Remove the outdoor unit cover and inspect for burnt wiring, melted connectors, or scorch marks around the compressor terminals and inverter module.
  • 2. Check power terminals: Tighten all mains and compressor terminal screws on the Camry outdoor unit. Loose connections can cause arcing and overcurrent.
  • 3. Clean condenser coil: Ensure the outdoor coil is clean to reduce compressor load. Follow the same cleaning procedure as for E3.
  • 4. Measure supply voltage: A qualified technician should verify that the supply voltage is within the range specified on the Camry nameplate.
  • 5. Test compressor windings: With power off and wires removed, measure compressor winding resistance and insulation to earth. Abnormal readings indicate a failed compressor.

Important: E5 typically requires professional service. Do not repeatedly reset and run the unit, as this may cause further damage.
