Since 1993, every new opener sold in the U.S. has been required to include photo‑eye safety sensors that meet the UL 325 entrapment standard, preventing the door from closing on people, pets, or property.​ When these sensors are knocked out of alignment, covered in dust, or damaged by weather, the opener will refuse to close—or worse, reverse unexpectedly—creating a major safety risk. Supreme Garage Door Repair provides fast, code‑compliant garage door sensor installation, alignment, and replacement throughout Dallas and the northern suburbs.
| Sensor Type | Location | Function |
|---|---|---|
| Photo‑Eye Pair | 4–6 in. above floor, each side of track | Infrared beam breaks if anything crosses, reversing door. |
| Edge Sensor | Bottom rubber astragal (commercial doors) | Stops the door when it detects resistance. |
| Tilt / Reed Switch | Attached to door panel | Sends open/closed status to smart opener. |
All residential openers rely on the photo‑eye pair; commercial doors may add edge strips for extra protection. Proper alignment means the two indicator LEDs glow solid—blinking or dark lights signal a fault.​
Door won’t close unless you hold the wall button
Flashing/blinking LEDs on one or both sensors
Door reverses when sun hits one sensor (beam interference)
Exposed or frayed wiring near the sensor brackets
Opener flashes 10 times then stops (common LiftMaster® error code)
If you notice any of these symptoms, stop operating the door and schedule a professional inspection.

You may be able to close the garage door by holding the wall control button, but bypassing the garage door safety sensors is not recommended. Disabling the sensors can create serious safety risks, may violate safety standards, and increase the chance of accidents or property damage. If your garage door sensors are not working properly, schedule a professional garage door sensor repair or replacement to restore safe and reliable operation.
Quality sensors last 7–10 years; sun exposure, lawn sprinklers, or accidental bumps can shorten lifespan.
Yes. many aftermarket photo‑eyes are UL‑listed and compatible with major brands. We carry OEM and universal options and will recommend the best fit.
No. All modern openers lock out remote and app control when they detect a sensor fault, so the door cannot close until the issue is fixed.
A garage door sensor may stop working due to misalignment, dirty sensor lenses, damaged wiring, or power issues. Faulty garage door sensors can prevent the door from closing properly and should be inspected as soon as possible for safety and reliable operation.
Yes, in many cases, a garage door sensor can be replaced without changing the entire garage door opener system. A professional garage door technician can inspect the sensors and recommend the best repair or replacement solution.
Common signs of misaligned garage door sensors include blinking sensor lights, the garage door reversing before fully closing, or the door refusing to close completely. Proper sensor alignment helps ensure safe and smooth garage door operation.
Blinking garage door sensor lights usually indicate that the sensors are misaligned, blocked by dirt or debris, or have a wiring issue. Professional garage door sensor repair can quickly identify the problem and restore safe, reliable garage door operation.
Garage door sensors should be inspected at least once a year as part of routine garage door maintenance. Regular inspections help detect alignment issues, damaged wiring, or worn components early, improving garage door safety and preventing unexpected repair needs.
