Photo-Eye Sensor Alignment or Replacement
The small light on one of the sensors near the floor has gone dark, or it flickers when someone walks past the track. The other one glows steadily.

Never bypass, tape over or relocate the sensors to make a door close; a door that reverses is reporting something worth fixing.
In plain words
By the end of the visit you have a door that closes from every control and reverses the instant the beam is broken, a sensor pair mounted level at the right height with steady indicator lights, wiring that is secured and out of harm's way, and a written note of what was found and what was changed. The technician walks you through the two tests you can repeat monthly, points out which light is which, and leaves the opener's diagnostic chart where you can find it. It is a small job that puts a large piece of your door's protection back in service.
How the visit goesSince shelving went up along the garage wall, the door will not close and both sensor lights are dead. A screw or staple may have gone through the thin wire that runs from the opener to the sensors.

How the visit goes
- 1
Clearing and walking the beam
Before anything is adjusted, the technician clears the strip of floor between the two sensors and looks along the beam line at sensor height. Things that break a beam are rarely dramatic: the corner of a recycling bin, a hose left coiled by the wall, a bag of salt, leaves blown in under the door, a cobweb bridging a lens, a new weatherstrip or track shoe that sits a little proud. Snow and ice piled inside the door in winter count too. With the path clean, the door is tried again, because a fair share of sensor calls end right here, with a lesson about where things can and cannot sit.

Cleaning and protecting the lenses
Lenses are wiped with a soft cloth and a mild cleaner, never scraped, and the housings are checked for cracks that let in water. Sensors that have been sitting in the strip where slush and salt collect are raised within the permitted height range and their brackets sealed. On a wall where the wire runs exposed, a slim protective channel keeps it clear of bins and bikes. Where mice have been at the wire, the new run is routed higher along the wall and dropped straight down to each sensor. These small measures are what keep a repair from repeating the following winter.

Keeping the brackets out of harm's way
Most repeat sensor calls come from the same few habits, and they are easy to change. Keep recycling bins, bicycles, boots and the snow shovel away from the bottom of the door track on both sides. Park with a little room to spare so a bumper never meets a bracket. When you sweep or blow snow out of the garage, aim away from the sensors rather than at them. If shelving or a workbench goes in along that wall, leave the strip near the floor free. The brackets are sturdy, but they hold a precise line, and a nudge that would not bother anything else is enough to lose the beam.

What affects the quote
- 1
Length and route of the wire run
A damaged section near a sensor is a short repair. A fresh run from the motor to both sides of the doorway takes longer, more so where the wire is buried in a finished ceiling.
- 2
Number of doors
Each opener has its own sensor pair and wire run, so a double garage with two doors is two sets of checks, two possible pairs and two rounds of testing, quoted per door.

Door-side findings
A balance problem, a stiff roller or a bottom seal that needs replacing sometimes shows up during testing. Those belong to their own service and are noted and quoted separately rather than hidden in the sensor work.

Photo-Eye Sensor Alignment or Replacement: questions
Can cold weather affect the sensors?
It can, in a few ways. Frost or condensation on a lens in an unheated garage dims the beam until it clears. The low winter sun reaches further across the floor and into a receiving eye. Old wire insulation cracks in the cold and shorts. Salt slush builds against brackets and corrodes them and the terminals over the years. Each of those has a straightforward remedy: cleaning, a shade or side swap, a fresh wire run, or brackets set above the slush line.
Why does my door start to close and then go straight back up?
Often the opener believes something is in the doorway, which happens when the receiving sensor stops seeing the beam, whether from an object in the path, a bracket knocked out of line, a dirty or frosted lens, sun in the receiving eye, or a damaged wire. Binding, a force setting or the door arm can cause the same symptom, so the sensor lights and the opener's flashing pattern are read first, and the technician fixes the cause they point to rather than guessing.
What tests are done before the technician leaves?
Two, and you are invited to watch. With the door closing, an object is passed through the beam and the door has to halt and climb back to the top. A 2x4 laid flat beneath the door's centre comes next; closing onto it must make the door back off on contact. The door is also run from the wall control and a remote, the opener's warning flashes are confirmed gone, and both sensor lights are shown steady.

What the census means at the door
8%
Newer homes. About 8% of homes in Vaughan were built in 1980 or earlier, according to the 2021 Census.
Newer houses often have a double door over a two-car garage, which means a heavier door, a pair of torsion springs and cables that must be matched exactly. Replacing springs on these doors is done in pairs so the door lifts level and the opener is not fighting one side.
63%
Mostly houses. Single-detached houses make up about 63% of homes in Vaughan (2021 Census).
Detached homes usually have their own driveway and apron, and years of freeze and thaw can leave the concrete uneven where the door meets it. A thicker bottom seal or a threshold strip closes the gap, keeping snow, leaves and cold air out of the garage.
