GUIDED TROUBLESHOOTING · Obstructions and reversal behavior

Door starts down then reverses

Distinguish a blocked path from reversal near the floor, and recognize when travel or mechanical diagnosis is needed. Start with safety before attempting any checks.

Stop if the door may be unsafe.

Keep everyone away from a crooked, falling, jammed or damaged door. Do not pull its emergency release, move it by hand, adjust springs or cables, or override safety sensors.
