Garage Door Guide
Why Won't My Garage Door Close All the Way?
A garage door that won't close — or closes partway and then reverses back up — is one of the most common calls we get across Kansas City. Here are the seven usual culprits, from a thirty-second fix to a job for a pro.
The 7 most common reasons a door won't close
Dirty or blocked photo-eye sensors
The two small sensors near the bottom of the tracks must see each other to let the door close. A spider web, road film, or a stray leaf across a lens is enough to stop the door and send it back up.
Misaligned safety sensors
If one sensor light is steady and the other blinks, they're out of alignment — bumped by a car door, a bike, or a snow shovel. Until they line up again, the opener won't close the door.
Something in the door's path
A trash can, a garden hose, or a box just inside the threshold can break the beam or physically block the door. Clear the opening and try again.
Debris or a dent in the track
A pebble, a buildup of grime, or a bent spot in the track can stop the rollers partway down. The door stalls at the same height every time.
The close-limit setting drifted
Openers have a travel limit that tells them where the floor is. If it's set too high, the opener thinks it hit the ground early and reverses; set too low, it pushes and bounces back up.
A binding cable or worn roller
A frayed lift cable or a seized roller makes the door drag on one side, trip the opener's force setting, and reverse. This one is a safety issue, not a DIY fix.
A weakening spring throwing off balance
As a spring tires, the door gets heavier and rides unevenly, so the opener senses too much resistance and stops. A door that's also slow or noisy points here.
Door reverses and a sensor light is blinking?
That's almost always the photo-eye sensors — the single most common cause. If a wipe and a nudge back into alignment don't fix it, A&E can realign or replace them fast, 24/7.
Quick checks you can safely do yourself
Start with the easy wins. Wipe both sensor lenses with a soft cloth and confirm both indicator lights glow steady — if one blinks, gently nudge it until it stops. Clear anything sitting in the doorway, and run your eye along the bottom of each track for a pebble, a clump of grime, or an obvious dent.
If your opener has a wall button with a lock or 'vacation' mode, make sure it isn't engaged. And if the door closes fine when you hold the wall button down but not from the remote, that's a strong sign the sensors — not the opener — are the problem.
When it's time to call A&E
If the sensors are clean and aligned, the track is clear, and the door still won't close, the cause is usually the close-limit setting, a binding cable or roller, or a spring that's losing its balance — all jobs that are safer and faster in a professional's hands. Cables and springs in particular are under high tension and are the leading cause of serious garage door injuries.
