Garage Door Safety Sensor Repair
A door that won't close, or reverses right before it hits the floor, is almost always the safety sensors - same-day diagnosis and repair. We provide fast, reliable, and expert service dispatch directly to your home.
All services are backed by our written warranty, performed by certified employees (no subcontractors), and dispatched same-day.
What We Handle
Every garage door opener sold since the early 1990s is required to have a pair of photo-eye safety sensors mounted a few inches off the floor on each side of the door - an invisible infrared beam between them that the opener checks before it will close. It's a simple system, but it's also one of the most common reasons an otherwise healthy garage door suddenly refuses to close, because the sensors are mounted exactly where they're most likely to get bumped, misaligned, or blocked.
Common Safety Sensor Problems
This is the classic sensor symptom - the opener starts closing, then immediately reverses, because it's reading a broken beam even though nothing is actually in the way.
Most openers refuse to close the door entirely (rather than just reversing) once they detect the sensors are misaligned or disconnected, as a built-in safety default.
A solid LED on both sensors means they're aligned and communicating; a blinking light on either one means the beam is broken or the alignment has drifted.
Intermittent failures are usually direct sunlight hitting a sensor at a certain time of day, a loose wire connection, or a sensor bracket that's slightly bent and drifting in and out of alignment.
Safety sensors exist specifically to stop a several-hundred-pound door from closing on a person, pet, or vehicle. Bypassing or disconnecting them to "fix" a closing problem removes that protection entirely and is never something we recommend, even as a temporary workaround - the correct fix is realigning or replacing the sensor, which is usually a quick, inexpensive repair.
What Happens During a Sensor Service Call
We check whether the sensors are physically aligned, whether the beam path is clear, and whether the LEDs indicate a solid connection on both units.
Sun-faded or squirrel-damaged wiring and bent mounting brackets are common causes we check for before assuming the sensor unit itself has failed.
Most calls end with a realignment; if a sensor's internal electronics have actually failed, we replace the pair from stock on the truck.
We test the door closing normally, then confirm it correctly reverses when the beam is intentionally interrupted, before we leave.

Frequently Asked Questions
Q: Why does my garage door reverse right before it touches the ground?
This is the single most common safety-sensor symptom - the opener is reading a broken beam between the two sensors, even if nothing is visibly blocking it, usually due to misalignment or something briefly in the path.
Q: What does a blinking light on my garage door sensor mean?
A blinking (rather than solid) LED means that sensor isn't receiving a clean signal from its pair - almost always an alignment issue, sometimes a wiring or power issue.
Q: Can direct sunlight cause garage door sensor problems?
Yes - strong direct sunlight hitting a sensor's lens at certain times of day can interfere with the infrared beam and cause intermittent reversing, which is worth checking before assuming a full sensor failure.
Q: Is it safe to disconnect the safety sensors if my door won't close?
No - the sensors exist to stop the door from closing on a person, pet, or vehicle. We don't recommend bypassing them even temporarily; realignment or replacement is usually a quick, inexpensive fix.
Q: Can I realign the sensors myself?
Loosening and re-aiming the brackets is straightforward in principle, but a slightly-off alignment can look fine and still fail intermittently - if a DIY attempt doesn't fully resolve it, a technician visit confirms it's correctly aligned rather than just appearing to work.
