Garage door reverses when closing?
A door that reverses while closing is obeying a safety response: the opener sensed an obstruction, real or false. Clear the floor and the photo-eye path first; if it keeps reversing with a clear opening, the sensors, wiring, settings, or a binding door need attention — not more retries.

Possible Causes
- 01 Photo-eye sensors not aligned (LEDs blinking instead of solid)
- 02 Sensor lenses dirty with cobwebs, dust, or moisture
- 03 Force-limit on opener set too sensitive (after door changes)
- 04 Track binding causing door drag the opener interprets as an obstacle
Safe First Checks
Stick to what you can see and what your door’s own manual asks of an owner — nothing more. Do not adjust springs, cables, drums, brackets, force, travel, or an unstable door.
- Compare both photo-eye indicator patterns with the exact operator manual
- Wipe both lenses gently with a soft dry cloth
- Use only the exact operator manual for user-approved sensor checks or alignment
- If the checks your manual allows are done and the door still reverses, stop — do not keep cycling it
When to Stop and Request Service
If both sensor lights look normal and the door still reverses, the easy fixes are off the table — something is binding or a setting has drifted. Stop cycling it (each reversal is wear) and tell us where it stops; that detail matters.
Frequently Asked Questions
Why does my door reverse just before fully closing?
Maybe — misaligned photo eyes are a frequent culprit, but a door can also reverse because something resists it: binding, floor contact, a drifted setting. If the sensor lights look normal, the cause is likely mechanical, and that’s worth a professional look.
Do I need to replace the photo-eye sensors?
Not necessarily. Check the indicator lights against your exact manual first — patterns differ by brand. If the lights check out and it still won’t behave, the problem has moved past the sensors, and forcing it won’t help.
