How to Fix / Troubleshooting
Safety first: Turn off power before accessing internal components.
- Check mode: Ensure the charger is configured to require RFID and that RFID is enabled in settings.
- Test multiple cards: Try several known-good cards or fobs.
- Inspect reader: With power OFF, verify the reader is securely mounted and its cable is connected to the main board.
If the reader remains unresponsive, replace the RFID reader module with a compatible United Chargers part.
