Possible Causes

Outdoor isolator switch off, Loose interconnecting cable between indoor and outdoor Camry units, Faulty outdoor PCB, Tripped compressor overload

How to Fix / Troubleshooting

Safety first: Turn off power before opening outdoor covers.

  • 1. Check outdoor isolator: Ensure the external switch near the outdoor unit is ON.
  • 2. Inspect interconnecting cable: Verify that the cable between indoor and outdoor units is intact and securely connected at both ends.
  • 3. Listen for relay clicks: When calling for cooling, listen at the outdoor unit for relay clicks. Silence may indicate PCB failure.
  • 4. Check for error codes: Some Camry models show outdoor faults on the indoor display; refer to any codes present.
  • 5. Technician diagnosis: If wiring and power are correct, a technician should test the outdoor PCB, compressor, and overload device.
