24-Hour Emergency Service · Same-day repairs across Plano & North Dallas
If your garage door starts to close then reverses, or the opener light blinks and it will not shut, Garage Door Repair Plano fixes it the same day across Plano, Texas. Nine times out of ten it is not the opener or the door, it is the two small photo-eye safety sensors near the floor, knocked out of line or with a dirty or failed lens. It is the cheapest repair on the whole door, and the one most often sold as something bigger. We are based in Plano on Greenbriar Lane in 75074 and we are insured.
Cheapest fix on the door

Quoted before we startSince 1993, federal law has required every garage door opener to have photo-eye safety sensors. Two small units sit a few inches off the floor, one each side of the door, and shine an invisible beam between them. If anything breaks that beam, a child, a pet, a bin, the door refuses to close. It is the system that stops a garage door crushing something underneath it.
So when a door will not close, the opener is usually working perfectly. It is doing exactly what it is built to do: refusing to close because the two sensors can no longer see each other. A bumped bracket, a spider web, a sun-faded lens or a loose wire is all it takes.
That is why Garage Door Repair Plano treats a reversing door as a sensor call first. It is a quick, inexpensive fix far more often than it is a new opener, and we would rather tell you that than sell you a motor you do not need.
When the sensors are unhappy, most openers flash a code. The light on the motor unit blinks a set number of times, or one of the little lights on the sensors themselves goes out or turns red. It is the opener pointing straight at the problem.
A steady green light on one sensor and a dark or red light on the other almost always means they are out of alignment, one has been nudged and is no longer aimed at its partner. A gentle re-aim fixes it. If both lights are dead, it is usually power, a chewed or pinched wire, or a sensor that has finally failed.
You can try the easy things yourself: wipe both lenses clean, check nothing is sitting in the beam, and look for a knocked bracket. If that does not do it, Garage Door Repair Plano will have it aligned or replaced in one short visit.
Sensor faults show up in a handful of clear patterns. Find yours, and it usually tells you whether it is a two-minute clean or a sensor that needs replacing.
| What you see | Most likely cause | The fix |
|---|---|---|
| Door starts down then reverses back up | Sensors out of alignment | Re-aim the sensors so the beam lines up again. |
| Opener light blinks and door will not close | Broken sensor beam | Clean the lenses, clear the beam, or realign. |
| One sensor light green, the other off or red | Misaligned or dead sensor | Realign, or replace the failed sensor. |
| Both sensor lights are dead | Power or wiring fault | Trace the wire for a pinch or chew, restore power. |
| Door only closes if you hold the wall button | Sensors bypassed on purpose | Do not leave it like this. It defeats the safety system. |
| Lenses are cloudy or sun-faded | Aged sensor eyes | Clean first, replace if the plastic has degraded. |
Almost always the safety sensors. A garage door that opens fine but reverses or refuses to close is the opener doing its job, blocking a close because the two photo-eyes near the floor cannot see each other. Garage Door Repair Plano can usually sort it in one short visit, and it is one of the cheapest fixes on the door.
They are a fault code, and for a door that will not close they nearly always point at the sensors. A blinking motor-unit light, or a sensor light that is off or red, means the beam is broken, either from misalignment, a dirty lens, or a wiring fault. Tell us what the lights are doing and we can often diagnose it on the phone.
Some of it, safely. Wiping both lenses clean, clearing anything sitting in the beam, and checking for a knocked bracket are all fine to try. What we would not do is bypass the sensors to force the door shut, because that removes the system that stops the door closing on a person or pet. If a clean does not fix it, call us.
No, please do not. Holding the wall button to force a door closed past its sensors defeats the one feature that stops it crushing a child, a pet or a car bumper. It is also against the safety standard every opener since 1993 has to meet. A proper sensor repair is quick and inexpensive.
It is one of the least expensive jobs on a garage door, and Garage Door Repair Plano quotes it before starting so there are no surprises. Often it is a simple realignment. If a sensor has genuinely failed, replacing the pair is still a small job. Call and describe the lights and we can usually get close on the phone.
