Why does my B&D PanelPro SDO-4V1 Tri-Tran+ Garage Door Opener courtesy light flash and beep?
- DDiana ScottAug 16, 2025
If your B&D Garage Door Opener's courtesy light flashes and beeps 5 times after each operation, it indicates that the opener has reached the recommended number of cycles before servicing. Contact your dealer to arrange a door service. Alternatively, you can press the SET button once to reset the service counter.
