Photo-Eye Sensor Alignment or Replacement
Since 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.

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
Two small sensors face each other across the doorway: one sends an infrared beam, the other receives it. While the beam lands on the receiver, the opener will close the door; the moment anything interrupts it, the door stops and returns to open. Every sensor call comes down to why the receiver has lost the beam: an object, a bent bracket, a dirty or frosted lens, sun in the receiving eye, a broken wire or a tired sensor. The technician works through those in order, fixes the one that applies, and shows you the steady indicator lights that mean the pair is talking again.
How the visit goesAfter a cold night the door stays open until the garage warms up. There is frost on the sensor lenses and a ridge of salty slush piled against the brackets where the snow blower was parked.

How the visit goes
- 1
Starting with the story
The first minutes are spent listening. What does the door do when close is pressed: drop and bounce, stay put, or close only while the wall button is held? Does the opener light blink, and how many times? When did it start, and what changed around then: a car bumped the track, a storm, shelving went up, the garage was reorganised, the first frost arrived? Does it happen at all hours or only on bright mornings? Those answers usually point at one of a handful of causes before a single tool comes out, and they decide whether the technician heads for the brackets, the wire or the head unit first.

Dealing with the sun
A receiver that looks into the low sun is fixed by geometry. The simplest cure is to swap the two sensors side to side so the receiver looks away from the doorway light and the sending eye, which is not affected, takes the sunny position. Where the layout rules that out, a small hood or shade is fitted over the receiving lens, deep enough to shield it without narrowing the beam path. The wiring is extended or re-routed as needed and both lights are checked at the time of day the fault used to appear, or with a strong light aimed at the lens to stand in for the sun.

Wiring that stays put
The wire between the head unit and the sensors has been secured along the ceiling and walls, clipped clear of the track and, where it was exposed, run inside a protective channel. Two things keep it that way. First, when anything is fastened to those walls or that ceiling, from shelving to a bike hook to drywall, look for the thin wire before driving a screw or a staple. Second, if mice have been in the garage, a chewed wire is a common sign, so a dark sensor light after a sighting is worth a look at the run. Either way, the sensor lights will tell you the moment the circuit is open.

Sun and reflection remedies
Swapping the sensors side to side is a small addition when the wiring reaches. Fitting a shade, or extending the wire so the receiver can move, is a little more and is listed on its own.

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.

Winter conditions on the day
Snow and ice packed against the brackets, a frozen bottom seal or a frozen floor where anchors must go all add a little clearing and care before the sensor work itself can start.

Photo-Eye Sensor Alignment or Replacement: questions
Could the wiring be the problem rather than the sensors?
Frequently. The sensors are fed by a thin two-conductor wire from the head unit that crosses the ceiling and drops down both sides of the door, and it is pierced by staples, cut by shelving screws, chewed by mice or pulled from its terminals more often than a sensor fails. Both sensor lights dark, or an opener code for an open or reversed circuit, points to the wire. The technician tests the run with a meter and repairs or replaces the damaged section.
Do sensors wear out with age?
They do, slowly. The infrared emitter and the receiver dim over many years, lenses craze or cloud from sun and salt, housings crack, and water finds its way in at floor level. A pair that needs re-aligning more and more often, or whose light drifts between steady and flickering with nothing touched, is usually ageing. Because pairs are matched to the opener, an older opener is worth identifying early so the right replacement is on hand.
Can the sensors be mounted on the wall instead of the track?
Track-mounted clips are the preferred, manufacturer-recommended arrangement. A wall-mounted angle bracket is the next choice where the track sits far back from the opening or the clip keeps getting bumped; mounting to the concrete floor is kept as a last resort, used only when the sensor's own instructions allow it. The same rules apply: both sensors at a matched height no higher than about 15 cm, level, facing each other, with the wire secured. Wall mounting sometimes gives a cleaner beam line on older doors with unusual track layouts.

What the census means at the door
58%
Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.
Extension springs are common on older doors, and they should carry a safety cable through the middle so a broken spring is held rather than flung. Adding those cables is a small job the technician checks for and offers on any older door he services.
23%
Single-detached houses make up about 23% of homes in Toronto (2021 Census).
Townhouse rows generally have a narrow single door on each unit, with shared walls on both sides. Noise from a chain opener or dry rollers carries straight into the neighbour's home, so quiet belt-drive openers and nylon rollers are a popular and considerate choice here.
