Safety Sensor Repair and Alignment

Fix photo-eye sensors that blink, block closing or reverse the door, and restore the safety feature properly.

Photo-eye sensors sit near the floor on each side of the door and watch for anything in the way. If something crosses the beam, the door stops and reverses. When a sensor is dirty, bumped or failing, the door may refuse to close, reverse for no reason or blink the opener light. Homeowners in Nashville call us when the door will not close and the light is flashing.

We check the lights on the sensors, clean the lenses, check the aim, trace the wiring for breaks and test the signal. We replace sensors that have failed and adjust brackets that have loosened. We also check the sun, since bright light can confuse a sensor. After repair we test the beam by waving an object through it and confirm the door reverses. It is worth testing your sensors every few months. Place a cardboard box in the path and close the door with the wall control. The door should stop and reverse. If it does not, stop using the opener with the remote and call us for a prompt repair.

Alignment

Sensors must face each other squarely. A bumped bracket can break the beam.

Clean lenses

Dust, spider webs and dirt can block the beam, and a simple wipe sometimes fixes it.

Wiring

Wires can be cut, chewed or loosened. We trace the wiring and repair it.

Replacement

Sensors that have failed are replaced with matched units. Never bypass them.

How it works

Our process, start to finish.

  1. 01

    Call and describe it

    You tell us what you want or what the door is doing, and we set an estimate visit that fits your day.

  2. 02

    Measure and plan

    We measure the opening and the headroom, side room and back room, check the framing and note options for the door, tracks and opener.

  3. 03

    Choose and confirm

    You get a plain written scope with the door model, insulation, hardware, opener and schedule, and you approve it before anything is ordered.

  4. 04

    Order and prepare

    The door and parts are ordered or built to your size, and we confirm the install day once they arrive.

  5. 05

    Install and adjust

    We remove the old door, set the tracks, hang the door, balance the springs, mount the opener and test every safety feature.

  6. 06

    Walk through

    We clean up, haul away the old door if you asked, walk you through the finished work and explain how to care for it.

Questions

Safety Sensor Repair and Alignment FAQ

Why is my opener light blinking?

Often a sensor problem. A blink pattern can point to a misaligned or blocked sensor.

Can I disable the sensors?

No. They protect people and pets, and bypassing them is unsafe.

Why does sunlight matter?

Strong sun can interfere with the beam. A shield or a position change can help.

How high should sensors be?

They are mounted a few inches above the floor. We set them to the right height.

Can wires be repaired?

Yes. We trace and repair or replace them.
