Few things are more annoying than a garage door that goes up fine but refuses to close — or closes halfway and reverses back up. If your garage door won't close in McKinney, TX, the good news is that the most common causes are quick to check, and many are fixable in a couple of minutes. Here's how to troubleshoot it before you call a pro.
1. Check the Photo-Eye Sensors First
This is the #1 reason a garage door won't close. Near the bottom of each track — about six inches off the floor — are two small "photo-eye" safety sensors that must see each other. If they're misaligned, dirty, or blocked, the door will refuse to close and the opener light usually blinks several times.
Fix it:
- Wipe both sensor lenses with a soft, dry cloth (cobwebs, dust, and grime are common culprits)
- Make sure nothing is blocking the beam — a trash can, bike, or even a loose cord
- Gently nudge the sensors until both indicator lights glow solid (not blinking)
2. Look for Obstructions and Track Problems
Run your eye along both tracks. A small object, a buildup of leaves, or a dented track can stop the door from sealing. A track that's bent or pulled loose from the wall will also cause the door to bind. Clear anything in the path — but don't try to hammer a bent track back into shape yourself, as that can throw the door further out of alignment.
3. Check the Opener's Travel and Force Settings
Every opener has "limit" settings that tell it how far to travel. If those settings drift, the opener may think the door is already closed, or it may hit the floor and reverse. These are adjustable, but if you're not comfortable doing it, it's a quick fix for a technician.
4. Rule Out a Broken Spring or Cable
If the door feels unusually heavy, sits crooked, slams down fast, or won't stay in place, the problem isn't the sensors — it's likely a broken spring or a snapped cable. Stop using the door. These components are under extreme tension and are dangerous to handle yourself.

Frequently Asked Questions
Why does my garage door go up but not close?
Most often it's the photo-eye sensors near the floor being misaligned, dirty, or blocked. Clean them and make sure both lights are solid. If that doesn't fix it, the springs, cables, or opener limits may need attention.
My opener light blinks when I try to close the door — what does that mean?
A blinking opener light almost always means the safety sensors aren't aligned or are blocked. Check and clean them first.
Is it safe to keep trying to close the door?
If it's just a sensor issue, yes. But if the door is heavy, crooked, or drops fast, stop — that points to a spring or cable problem that needs a pro.
