Door opens but will not close fully; logic board LED flashes 6 times, pause, then 2 times (6-2).

Safety first: Do not increase force to overcome a physical obstruction. Correct mechanical issues first.

Steps to fix:

• Inspect floor area: Remove any objects or debris from the door threshold.
• Adjust down travel: Reduce the DOWN travel slightly so the door stops just at the floor without pushing hard.
• Adjust down force: Reduce the DOWN force setting to the minimum that reliably closes the door.
• Re-run travel setup: Perform a full travel reprogramming per the manual to synchronize limits and force.
