Possible Causes

Blocked outdoor coil on Camry condenser, Outdoor fan failure, Low refrigerant charge causing overheating, Faulty compressor thermal protector

How to Fix / Troubleshooting

Safety first: Turn off power and allow the outdoor unit to cool completely.

  • 1. Clean outdoor coil: As described for E3, ensure the coil is clean and unobstructed.
  • 2. Verify fan operation: Confirm that the outdoor fan starts and runs at full speed whenever the compressor is running.
  • 3. Check ambient conditions: In extremely high outdoor temperatures, reduce indoor load (raise setpoint) to reduce compressor stress.
  • 4. Professional checks: A technician should verify refrigerant charge and inspect the compressor thermal protector and windings.
  • 5. Avoid repeated resets: Do not repeatedly restart the unit after H2; this can permanently damage the compressor.
