Possible Causes
Failed microcontroller on FAAC PCB, Surge or lightning damage, Corrupted firmware, Shorted component on logic board
How to Fix / Troubleshooting
Safety: Turn off power at the breaker and wait several minutes before opening the control housing.
- Power cycle: Disconnect mains power for 2–3 minutes, then restore. Sometimes a transient fault clears after a full reset.
- Inspect for surge damage: Look for burn marks, swollen capacitors, or melted tracks on the FAAC control board. If present, the board must be replaced.
- Disconnect peripherals: Remove all non-essential wiring (photocells, keypads, external receivers) and test with only power and motor connected. If E9 remains, the board is defective.
- Check grounding and surge protection: Ensure the opener is properly grounded and consider adding a surge protector to prevent future damage.
- Replace control board: Order the exact FAAC replacement PCB for your model and transfer all wiring one terminal at a time to avoid mistakes.
Firmware updates, if available, should only be performed by authorized FAAC service personnel.
