How to Fix / Troubleshooting
Safety: This is a low‑voltage fault; risk is minimal but avoid opening the unit unless qualified.
- Test multiple RFID cards/fobs: Try more than one authorized card. If none are recognized, the reader or configuration is suspect.
- Check app or backend settings: If your Amperfied charger is connected to a backend, verify that RFID authorization is enabled and that your cards are correctly registered.
- Power‑cycle: Turn off the charger at the breaker for a few minutes, then restore power and test again.
- Technician steps: A technician can remove the front cover, check the RFID reader wiring harness, reseat connectors, and replace the RFID module if it fails functional tests.
