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.

phone_in_talk778 805-4911The safety sensors are likely misaligned or blocked. When the beam is interrupted, the door reverses as a safety measure. Check for dirt on the sensor lenses and make sure nothing is blocking the beam.
The two sensors need to face each other directly. The LED lights show alignment status — both should be solid (not blinking). We can realign them quickly during a service visit.
Yes. Heavy rain or water spray can damage sensor units. If you see corrosion or cracked plastic on the sensors, they need replacing.
Sensor replacement is one of the more affordable garage door repairs. Most jobs cost under $100–$150 for parts and labour.
