A garage door that won't close is almost always a sensor problem, a track or remote issue, or a broken spring or cable. Sensors and remotes are safe to check yourself. Springs and cables are not, and a door that won't close is also a security gap worth fixing the same day.
Match the Symptom to the Cause
- Reverses before touching the floor: an obstructed or misaligned photo-eye, mechanical binding or travel setting can be responsible.
- Only closes while you hold the button: also usually a sensor issue.
- Won't move at all: check power and the remote first.
- Closes unevenly or drops quickly: possible broken spring or cable. Stop using it.
- Stiff or slow in cold weather: thick lubricant, a seal sticking to the floor or mechanical binding are possible. Do not assume it is safe to force.
Safe Checks You Can Do
Sensor Alignment
The two sensors sit a few inches off the floor on each side of the door and must face each other directly. With the door stationary and everyone clear of its path, clean the lenses and remove an obstruction only if you can reach it safely. Adjust only the sensor's own alignment fastener as its manual directs, keeping the beam no higher than six inches; do not loosen track supports or rewire the system.
Track and Remote
Look at the tracks for obvious dents, debris, or gaps, and call a professional for anything beyond light cleaning. For the remote, replace the batteries and confirm the opener's antenna hangs down freely.

What Needs a Professional
A broken torsion spring or a frayed or snapped cable can stop a door from closing evenly, and both are under tension that makes them dangerous to handle without the right tools. If the door closes unevenly, drops quickly, or you can see damaged hardware, stop using it and call.
FAQ
Can I use my garage if the door won't close?
You can, but it's not advised. An open garage is a security risk, and a door that won't close properly can fall or shut unexpectedly.
Why does my door close then immediately reopen?
If it touches the floor and then reverses, close travel may be set too far or the door may bind. If it reverses before contact, check the photo-eyes and obstructions. Do not increase closing force to make it shut; have persistent reversing diagnosed.
Why won't my door close all the way?
Check for visible obstructions and note whether the door stops before or after touching the floor. If clean, correctly aligned sensors do not resolve it, have the travel, rollers, track and springs inspected.
