Garage door problems
Garage door won’t close
A garage door that won’t close is most often stopped by the photo-eye safety sensors near the floor: something blocks the beam, the eyes are knocked out of line, or a lens is dirty.

The short answer
A garage door that won’t close is most often stopped by the photo-eye safety sensors near the floor: something blocks the beam, the eyes are knocked out of line, or a lens is dirty.
Federal rules require that safety system on every home opener made since 1993, so the opener refuses to close when it cannot see a clear path. Check the sensors, the wall-button lock and the track before anything else.
If this is happening now
Stop and leave the door alone if you see a broken spring (a gap in the coil above the door), a loose or snapped cable, a door off its track or hanging crooked, or a door that has fallen.
Do not run the opener and do not pull the release cord on an open door: the springs and cables hold enough stored energy to cause serious injury, and CPSC says a door that is out of balance should be serviced by a professional.
Keep people and cars clear and call a garage door technician. You can also reach HyreGarage on (866) 582-8523.
Key takeaways
A blocked or misaligned beam is the usual reason a door refuses to close.
No movement, a short drop then reversal, or a stop near the floor each point somewhere different.
They are the legal safety device that stops the door on a child or pet.
Leave the door where it is and call a technician.
What can I safely check when the door won’t close?
These checks involve no springs, cables or tension. Do them with the door open and the opener plugged in.
Look for a bin, a broom, leaves or a cobweb between the two sensors about six inches off the floor.
On most openers both sensors show a steady light. A dark or blinking one means the pair cannot see each other. Nudge it back by hand until the light holds steady.
Dust, spray or condensation on a lens can break the beam.
Some sensors misread when the sun shines straight into one lens at certain times of day.
On many openers, holding the wall button closes the door even when the sensors fail. Watch the door the whole way and let go if anything is in its path.
A wall control set to lock disables the remotes but usually not the wall button.
What does a technician check if the sensors are fine?
A staple through the low-voltage wire or a corroded joint gives the same symptom as a blocked beam.
If the door touches the floor and reverses, the close limit or force setting is out.
A bent track or binding roller makes the opener sense resistance and reverse.
A door with a weak spring is heavy, and the opener may stop to protect itself.
What does each symptom point to?
| What you see | Most likely cause |
|---|---|
| Nothing moves, opener light blinks | The sensors cannot see each other. Start with alignment and the beam path. |
| Door drops a few inches, then goes back up | Sensor beam broken as the door starts, often by a loose wire or a lens that flickers. |
| Door reaches the floor, then reverses | Close limit set too far or the force too low. See garage door keeps going back up. |
| Door stops partway and will not move | Something binding in the track, or a balance problem. Do not force it. |
| Remote fails, wall button works | Remote battery or the lock setting. See garage door remote not working. |
What to ask before you sign
Ask which part caused the fault and to see it before any part is replaced.
The door should reverse on a 2x4 laid flat on the floor, as CPSC recommends monthly.
A heavy door can cause close faults that new sensors will not fix.
Ask whether parts are still made for it before paying for a board.
The full ten-point checklist is on choosing a garage door company.
Where this goes wrong
It removes the device the federal rule requires to stop the door on a person. It also hides the real fault.
Most close failures are alignment or wiring. A new opener with the same wiring problem fails the same way.
If the door is stuck partway, pulling it down by hand can load a damaged spring or cable. Leave it and call.

Primary-source research, data analysis and fact checking
We are not a garage door company. We read the agency file, the code record, the standards document or the public register ourselves, compute the figure from it, and publish it with the source and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. Our own company records cover ten states; nothing national is ever derived from them.
- 10
- states our own company records cover — and the limit of any claim made from them
- 3,901
- garage door companies in the store
- 457
- license records verified against a state board

How this desk works
- Primary sources only. Injury counts come from CPSC. Housing counts come from the Census file, not from a summary of it. Code history comes from the building commission that adopted the code. We do not cite an article that cites a source; we retrieve the source and do the arithmetic ourselves.
- Every figure carries its retrieval date. Registers change, datasets are revised and codes are amended. A number without the date it was read cannot be checked, so every study states one.
- Fact, calculation and analysis are labeled apart. A quote is a quote, a HyreGarage computation says so, and an interpretation says “HyreGarage analysis”. Presenting our reading of a dataset as something the agency stated would be the easiest way to lose the only thing this desk is for.
- Limitations go above the fold. If a figure is an upper bound, a bracket, or an association rather than a cause, that is said before the figure is quoted rather than in a footnote underneath it.
- No DIY instructions for spring, cable or track work. Those components hold enough stored energy to cause serious injury, and CPSC records the consequences. We describe what has failed and what a competent repair involves; we do not tell you how to do it.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.

Information on this page is general and varies with the door, the opener, local code and circumstance. It is not safety, insurance or legal advice.
Springs and cables hold dangerous stored energy: adjusting or replacing them is work for a trained technician. HyreGarage does not repair, replace or install garage doors.
