Garage Door Won't Close?
Here's What's Going On
Honest diagnosis for Fort Lauderdale, FL homeowners — what usually causes it, what to do right now, and how the repair works.
Sound Familiar?
The door goes up fine, but when you try to close it, it either refuses to move, or travels partway down and reverses back up — often with the opener light flashing.
Why won't my garage door close?
The most common reason is the photo-eye safety sensors: misaligned, dirty, or blocked sensors make the opener refuse to close (and often flash its light). Close-limit and force settings, or a track obstruction, come next.
Closing is the direction with all the safety systems, because a closing door can hurt someone. Federal law requires openers to reverse if anything interrupts the photo-eye sensors near the floor or if the door meets unexpected resistance. So a door that won't close is very often a safety system doing its job — the question is whether it's reacting to a real obstruction or a false alarm.
The Most Likely Causes
1. Blocked, dirty, or misaligned safety sensors
This is the cause in the clear majority of won't-close calls. The two small photo-eyes near the bottom of the tracks must see each other perfectly. A bumped bracket, cobwebs, condensation on the lens, or a garbage can edge in the beam path will make the opener refuse to close — usually with a blinking opener light or flashing sensor LED as the tell.
2. Travel limit or force settings out of adjustment
If the opener believes the door has hit the floor before it actually has, it reverses as though it struck an obstruction. Settings drift over time, and a door that reverses at the same point near the floor every time often just needs its limits professionally reset.
3. A binding track or failing rollers
Anything that makes the door physically harder to move on the way down — a bent track, a seized roller — trips the opener's force limit and triggers a reversal partway through travel.
4. Broken springs changing the door's balance
A door with a failed spring closes with far more momentum than the opener expects. Some openers detect the imbalance and refuse to run; others slam the door down, which is its own hazard.
What to Do Right Now
Check the sensors first: look for a steady (not blinking) LED on both photo-eyes, wipe the lenses, and clear anything near the beam path at ankle height. If the door will only close while you hold the wall button down, that confirms a sensor problem — that's the opener's built-in override mode, not a fix. Don't leave the door open overnight while you wait; if you can't get it closed safely, it's worth an emergency visit to secure the house.
