Photo-Eye Sensor Alignment or Replacement in Long Branch
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
Most sensor visits end in alignment rather than new parts. The brackets that hold the sensors ride on the door track or the wall, and they get bumped by bins, tires and shovels until the two lenses no longer look at each other. The technician resets both sensors to the same height, loosens the wing nuts, aims the pair until the receiving light holds steady, tightens everything and secures the wire. Replacement is the answer when a lens is crazed, a housing is cracked, water has got inside or the indicator stays dark with good wiring, and then a pair matched to the opener is fitted.
How the visit goesYou press the remote, the door drops a few centimetres, then climbs straight back to the top while the opener light blinks. Nothing is under the door. It has done this every evening this week.

How the visit goes
- 1
Ruling out sun, frost and reflections
A sensor that misbehaves on a timetable is usually being blinded rather than broken. The technician notes which way the door faces, where the low sun reaches the floor in the morning and late afternoon, and whether a receiving lens looks into that light or into a reflection off a parked car, a white wall or fresh snow. Lenses are checked for frost, condensation and a film of salt, common in an unheated garage. A hand cupped over the receiving eye while the light is watched is a simple test: if the indicator settles when the eye is shaded, the fix is a side swap or a small hood rather than new parts.

Straightening or replacing the brackets
A bent bracket is straightened where the metal allows and replaced where it has cracked or rusted through. New brackets are chosen to suit the mounting: a track-mounted clip that rides the vertical rail, or a right-angle bracket anchored to the wall or the concrete where the track sits too far back. Fasteners that vibrated loose are replaced with the right carriage bolts and wing nuts rather than reused. Where a bracket has been sitting in salt slush every winter, it is set a touch higher within the permitted range and the mounting is sealed against the wall so water stops running behind it.

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.

What affects the quote
- 1
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.

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.

Opener make and generation
Sensor pairs are matched to the opener family, and some models take a kit with brackets and wire while others take sensors alone. The head unit label sets which pair is needed and how it is priced.

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.
Older houses frequently have a garage door that was replaced once already, sometimes with a door chosen for the opening rather than the building. When that door reaches its end, there is a chance to pick a style that suits the house properly, and we measure with that in mind.
23%
Single-detached houses make up about 23% of homes in Toronto (2021 Census).
Attached housing frequently has tandem or tight garages with limited headroom and little side room, so replacement openers and tracks are chosen to fit those dimensions. A low-headroom track kit or a wall-mounted jackshaft opener often solves what a standard unit cannot.
