Can I just tape the two sensors together up near the ceiling?

Never do this. Bypassing safety reversing eyes is a severe fire and safety violation that creates catastrophic crush hazards for children and pets and voids homeowner insurance liability.

What color should the lights on my garage door sensors be?

On Chamberlain/LiftMaster units, the sending eye glows steady amber/yellow (power) and the receiving eye glows steady green (aligned). If the green light is flickering or off, the sensors are misaligned.

Texas Garage Door Safety Sensor Alignment & Wiring Repair

Under federal safety standard UL 325, every automated residential garage door must feature an active entrapment protection device. Safety photo-eyes sit 6 inches above the floor on each track. If one sensor is knocked out of plumb, blinded by Texas afternoon sun glare, or suffering from severed low-voltage bell wire, your garage door will refuse to close, reversing instantly and flashing the opener lights. Local technicians diagnose sensor beam degradation, re-align optical lenses, repair wire staple shorts, and replace broken photo-eye brackets on all systems.

Door refuses to close when you need to leave for work or secure your home at night? Emergency technicians are available 24/7 for urgent sensor repair.

Call (800) 240-4326Average repair window: Sensor alignment and rewiring takes 30 to 45 minutes.

Signs You Need Sensor Repair & Alignment

The door begins closing, reverses immediately, and overhead opener lights flash 10 times

One photo-eye LED is glowing steady green/amber while the opposite sensor is completely unlit or flickering

The garage door only closes if you continuously hold down the interior wall control button

Safety sensors vibrate out of alignment whenever the garage door operates

Sensors only fail in late afternoon when direct sun hits the optical receiver lens

Underlying Root Causes

Physical impact from lawn mowers, trash cans, bicycles, or car tires knocking brackets out of line
Low-voltage bell wiring severed, chewed by rodents, or pinched by tight framing staples
Dust, cobwebs, or insect nests coating the optical infrared sender lens
Direct bright sunlight overpowering the infrared receiver beam during sunset hours

How Our Dispatched Technicians Perform This Service

Technicians follow rigorous mechanical standards to guarantee that your garage door is balanced, lubricated, and safe for family use.

Voltage & Optical Beam Verification

Technicians check low-voltage millivolt supply from the opener logic board to determine whether the issue is power, wiring, or lens alignment.

Precision Infrared Alignment

Laser alignment tools calibrate sender and receiver photo-eyes across the doorway to ensure unbreakable line-of-sight communication.

Heavy-Duty Bracket Reinforcement

Flimsy, bent mounting brackets are replaced or anchored firmly into track framing to eliminate operational vibration misalignment.

UL 325 Entrapment Testing

Technicians conduct mandatory 1.5-inch block obstruction tests to guarantee the door immediately reverses upon contact or beam break.

Important Homeowner Safety Notice

Bypassing or cutting sensor wires leaves your 300-pound door without auto-reversal, creating dangerous liability and potential physical injury.
