How to Fix / Troubleshooting
Safety: Turn off power before reseating connectors.
- Power reset: Switch off mains power for 1–2 minutes, then restore and test operation.
- Check connectors: Gently press all plug-in connectors on the control board (motor, encoder, BUS, sensors) to ensure they are fully seated.
- Inspect supply quality: If possible, connect the opener to a clean power source or use a surge suppressor.
- Firmware update: If BFT provides firmware updates for your model, have an authorized technician update the control board.
