Can I align the sensors myself?

You can try gently cleaning the lenses and nudging the brackets until both indicator lights stay lit. If the lights still blink or the door still reverses, the issue may be wiring or a failed sensor, and a pro should take over.

Why does my door reverse even though nothing is in the way?

Sunlight hitting a sensor lens, vibration loosening a bracket, or a cobweb across the beam can all fake an obstruction. A pro can tell which one it is and fix it properly.

How much does sensor replacement cost?

Pricing varies by opener brand and model, so the pro will give you a free estimate on site before doing the work. Many alignment visits need no new parts at all.

Garage Door Photo Eye Sensor Alignment in Atlanta, GA

Garage door photo eye sensor alignment is the adjustment of the two small sensors mounted near the bottom of your door tracks so their invisible beam lines up perfectly. When the beam is broken or misaligned, the door refuses to close or reverses back up. A local pro can realign, clean, and test the sensors so the door closes reliably again.

Atlanta garages collect dust, cobwebs, and pollen that cloud sensor lenses, and a stray bump from a bike or trash can knocks them out of line. It is one of the most common reasons a door will not close here. Call (678) 940-0457 and we will connect you with a local pro who can sort it out and give you a free estimate if a sensor needs replacing.

What sensor alignment service includes

A proper sensor service goes beyond nudging the brackets. The pro verifies the whole safety circuit so the door reverses exactly when it should.

Cleaning dust, cobwebs, and pollen from sensor lenses
Realigning both sensors until indicator lights hold steady
Tightening sensor brackets and checking mounting height
Inspecting wiring for nicks, staples, and loose connections
Testing the auto-reverse response with an obstruction
Replacing failed sensors when alignment will not hold

Signs your photo eyes need alignment

The giveaway is a door that starts down and immediately reverses, especially with blinking lights on the opener or the sensors. If one sensor shows green and the other shows red or nothing at all, the pair is not seeing each other.

Holding the wall button down to force the door closed is a workaround, not a fix. It bypasses the safety system, which exists to protect kids, pets, and cars. Get the alignment corrected so the safety features work as designed.

What happens when you call

Calling (678) 940-0457 puts you through to an independent Atlanta pro who aligns safety sensors daily. They will inspect the sensors and wiring, realign and test everything, and quote a free estimate on the spot if a replacement sensor is required. Most visits wrap up quickly.
