Garage door safety sensor repair
A door that starts down and goes straight back up is not broken. It is doing what federal law requires: the photo-eye sensors near the floor believe something is in the way.
Typical cost
$115 – $200
realignment or a new sensor pair
Time on site
30 – 45 minutes on site
What actually goes wrong
The two sensors face each other across the opening and one shines an invisible beam at the other. Anything that breaks the beam stops the door. Most of the time nothing is in the way at all — one sensor has been nudged out of alignment by a bike, a bin or a foot.
The second most common cause is a film on the lens. In a garage that doubles as a workshop or a gym — which describes half of Coral Springs — dust settles on the lens and scatters the beam. A wipe fixes it, and we will tell you that on the phone before sending anyone.
When it is not the sensors
If both indicator lights are steady, nothing is in the path, and the door still reverses at the same point every time, the fault is the close-limit setting on the opener. It believes the floor is lower than it is, meets resistance and reverses. That is an adjustment screw, not a part.
Questions about safety sensor repair
Can I just disconnect the sensors?
No. They have been a federal requirement on every opener sold since 1993 and they are the reason garage doors no longer close on children and pets. We will not bypass them.
One sensor light is completely off.
Usually a broken wire, often where it was stapled to the frame years ago. That is an inexpensive repair, not a replacement.
