Possible Causes
How to Fix / Troubleshooting
Safety first: Turn OFF power before cleaning vents or opening the unit.
Steps:
- Check installation clearance: Ensure the Lucid charger has the minimum side/top/bottom clearances specified in the manual. Remove any stored items blocking airflow.
- Clean vents: Use a vacuum with a brush attachment to gently remove dust from intake and exhaust grilles.
- Ambient temperature: If installed in a hot garage, try charging during cooler hours. High ambient temperature can trigger E07.
- Listen for fan: During startup, you should hear the internal Lucid cooling fan. If silent, the fan may have failed.
Technician actions:
- With cover removed and power OFF, spin the fan blades by hand to check for binding.
- Verify fan connector is seated on the Lucid control or power board.
- Replace the Lucid cooling fan assembly if inoperative, and inspect thermal sensors on the power module.
Resolution: After restoring airflow or replacing the fan, clear the error by power-cycling and monitor temperature readings if available in the Lucid app.
