Photo-eye sensors
Dirty, blocked, misaligned, or damaged safety sensors can interrupt closing. Their safety function should remain enabled.
Common causes
Why a garage door reverses or stays open
Tracks and hardware
Obstructions, damaged rollers, bent track, or an uneven door can create resistance and trigger reversal.
Opener and controls
Travel settings, controls, wiring, or opener components may require inspection when the path is clear.
Safe checks
What you can check first
- Remove visible objects from the doorway.
- Gently wipe sensor lenses without changing their mounting.
- Check whether both sensor indicator lights are on.
- Stop if the door is crooked, noisy, or has loose cables.

Garage door closing questions
Why does the door start down and go back up?
The opener may detect an obstruction or sensor problem, or the door may be binding. If the opening is clear and sensors are unobstructed, request an inspection.
Can I hold the wall button to bypass the sensors?
Do not bypass or defeat a safety system. Keep the opening secure by other safe means and arrange service.
