Door stops slightly open and will not fully close; small gap remains at the floor.

Safety: Keep clear of the door bottom while adjusting limits.

• Identify limit controls: On FAAC openers, locate the open and close limit adjustment screws or cams on the rail or control board.
• Adjust close limit: Turn the close limit adjustment in small increments in the direction indicated to increase travel until the door just contacts the floor.
• Compensate for new seal: If a new bottom seal was installed, additional travel may be needed to compress it slightly.
• Test several cycles: Run the door open and closed multiple times to confirm consistent full closure without excessive force.

Do not over-adjust so that the door presses hard into the floor; this can damage the opener and door.
