Safety sensors prevent your door from closing on people, pets, or objects. If the door reverses for no reason or the sensor LED blinks amber, we diagnose, realign, or replace the photo-eye sensors to restore safe automatic operation.
Photo-eye safety sensors work by shooting an invisible IR beam across the door opening. Anything that blocks, misaligns, or dirties the beam triggers the safety reversal.
Bumped sensors no longer face each other accurately — the beam misses the receiver.
Afternoon sun overwhelming the IR receiver causes false reversal triggers.
Dust, spider webs, or moisture on the lens diffuses the beam below detection threshold.
Pinched or corroded sensor wires cause intermittent or permanent signal loss.
Most sensor issues are resolved in under 20 minutes. We carry replacement sensors for all major opener brands.
We realign sensors to ±1mm using a level and test beam confirmation.
Lenses cleaned with isopropyl alcohol for maximum IR transmission.
Full wiring run checked for pinch points, breaks, and corrosion.
Brand-matched replacement sensor pairs on the truck for same-day swap.
