Garage Door Sensor Services in Dallas, TX
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, close unpredictably—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.
How Garage Door Sensors Work
| 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 door when it meets 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.
Signs Your Sensors Need Service
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.

Garage Door Sensor - FAQ
Can I bypass the sensors to close the door?
Holding the wall button forces the door to close, but bypassing sensors long‑term violates UL 325 and puts people at risk. Schedule a repair instead.
How long do photo‑eye sensors last?
Quality sensors last 7–10 years; sun exposure, lawn sprinklers, or accidental bumps can shorten lifespan.
Are universal sensors reliable?
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.
Will smart openers still work if the sensors fail?
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.
