How to Fix / Troubleshooting

Safety first: Overcurrent faults involve dangerous voltages and currents; only qualified technicians should perform detailed tests.

  • 2. Measure current draw: A technician should use a clamp meter to compare actual current with the rated current on the Camry nameplate.
  • 3. Test windings: Measure resistance and insulation of compressor windings.
  • 4. Check refrigerant system: Verify that the system is not overcharged and that there are no restrictions.
  • 5. Replace faulty parts: Depending on findings, replace the compressor, current sensor, or outdoor PCB.
