Garage Door Won't Close? Nine Causes, Ranked by How Common They Are

Published 2026-05-06 6 min read Titan Overhead Garage Doors TX

A door that opens perfectly but won't close is one of the most common calls we get, and it's also the one most likely to be solved by the homeowner in ten minutes. Work down this list in order.

1. Safety sensors, misaligned (by far the most common)

The two photo eyes near the floor must see each other. Any knock, a bike leaning on one, or a loose bracket breaks the beam and the opener refuses to close, because a door that closes on something it can't see is exactly what those sensors exist to prevent. Look for one steady light and one blinking. Loosen the wingnut, adjust until both are steady, tighten.

2. Sensor lenses dirty or sun blinded

Dust, cobwebs, or, in Texas particularly, low afternoon sun shining directly into the receiving eye. The sun problem is seasonal and maddening: the door closes fine all day and refuses at five in the evening. Small sun shields solve it.

3. Something genuinely in the path

Obvious, but worth a look. A stray recycling bin, a coiled hose, or a build up of leaves under the seal will all trigger a reversal.

4. Close travel limit set wrong

The opener thinks the floor is higher than it is, hits the programmed stop early, and reverses. Adjustable on the motor unit. If your door started this after a power outage or a battery change, this is a strong candidate.

5. Close force set too low

Weather changes the friction in a door. A setting that worked in mild weather may not overcome stiff seals in winter. Nudge the force setting slightly, then re-test the auto reverse with a solid object on the floor. Never raise the force to overcome a real obstruction.

6. Damaged or pinched sensor wiring

Low voltage wire stapled along a stud, nicked by a staple, or chewed by rodents. Symptoms come and go with temperature and vibration. Follow the wire visually along its whole run.

7. The remote or wall button is stuck

A jammed button sends a constant signal, and the opener interprets a hold as a command not to close. Unplug the wall console and try the remote alone to isolate it.

8. The door is binding in the track

Now we're past DIY. If the door judders, sits crooked or catches at a specific point, the opener is reading real resistance and correctly refusing. This means bent track, a worn roller, or cable tension that has drifted, and it's the beginning of a door coming off track. Book off track and cable repair before it gets worse.

9. Broken spring or cable

Less common in a door that opens fine, but possible on a dual spring system where one has gone. Check for the two inch gap in the coil and look for slack or tangled cables at the top corners. If either is present, stop using the opener and call for spring repair.

The one test to always run afterwards

Whatever you adjusted, finish by laying a solid object flat on the floor in the door's path and closing the door. It must contact and immediately reverse. If it doesn't, the force setting is now unsafe and needs turning back down. This test takes thirty seconds and it's the whole point of the system.

A door stuck open is a security problem

If you can't resolve it and the door is stuck open, don't leave it overnight. The manual release lets you close and lock the door by hand as a stopgap, and we run 24 hour emergency call outs for exactly this. A garage standing open all night is an invitation, particularly with an interior door into the house.
