How to Fix / Troubleshooting

Safety: Disconnect power and use locking pliers on the tracks to prevent the door from falling while working.

Inspect tracks: Look along the full length of both tracks for bends, dents, or screws protruding into the path.
Check rollers: Spin each roller by hand; replace any that are seized, cracked, or wobbling.
Realign track: Loosen the mounting bolts slightly, tap the track into correct alignment (parallel and plumb), then retighten.
Test manually: Move the door by hand through the problem area. It should glide smoothly. Only then reconnect the FAAC opener and test powered operation.

Do not increase opener force to overcome a mechanical obstruction; fix the door hardware instead.

Door starts to open or close then stops and reverses at the same point every time, with no displayed error.
