Remove obstruction. Re-learn force. | | 3 blinks | Photo eye error | Clean lenses. Align sensors. Check wiring. | | 4 blinks | Motor temperature too high | Wait 20 minutes for cooling. Improve ventilation. | | 5 blinks | Internal logic board fault | Cycle power. If persists, replace control PCB. | | Continuous fast blink | Radio interference | Change remote channel or move large metal objects away. |
