Photo-Eye Sensor Alignment or Replacement
Someone backed the car in a little too far, a bin or a bicycle brushed the track, and since then the door starts to close and comes back up. One sensor now sits at a slightly different angle from the other.

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
If your opener has no sensors at the floor, that alone does not date it, since a pair can be missing, removed or never reconnected; the technician identifies the model before deciding whether a pair can be restored or the operator itself needs replacing. The visit is still worth making: the technician tests contact reversal and sets out what a modern operator brings, including a matched sensor pair, force reversal and a monitored circuit that holds the door open until the beam clears. Where sensors are present but tucked up beside the motor, they are returned to the doorway where they belong.
How the visit goesThe door will only go down while a finger stays on the wall button; let go and it stops or reverses. From the remote it opens fine but never closes, so someone has to stand in the garage every time.

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.

Proving it with the two tests
No sensor job is finished on a steady light alone. The door is closed from the wall control and from a remote, and while it is on its way down an object is passed through the beam; the door must stop and return to fully open. Then a 2x4 is laid flat on the floor under the centre of the door and the door is closed onto it; it must reverse on contact. Both are repeated, the opener's diagnostic light is confirmed clear, and any app or hub reporting a sensor code is refreshed. The customer watches the tests so the normal behaviour is seen, not described.

If it ever reverses again
Should the door start bouncing back up in the future, you know the order to check. Look along the floor for anything in the beam. Look at the two sensor lights for a dark or flickering one. Look at whether the door backs up as soon as it starts or only after touching something, since the second points to the door's settings rather than the beam. Note whether the opener light is flashing and how many times. With those four facts the cause is usually obvious, and if a visit is needed, the technician arrives already knowing where to begin.

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.
- 2
Corrosion reaching the head unit
Where salt and water have travelled up the wire to the terminals, or the sensor terminals on the board are damaged, the repair extends beyond the pair and that is set out separately.
- 3
Access to the doorway and the head unit
A clear strip along the floor and a reachable head unit make for a direct job. Shelving, vehicles or stored goods that must be moved to reach the sensors, wire or terminals add time.

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.
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.
The opener light blinks when I press close. Is that the sensors?
Very often, yes. A blinking bulb after a close command is the opener reporting that its sensor circuit is unhappy, and the count of blinks is the message: one common family uses ten flashes for the sensors, while a short two-flash pattern usually means the wall control's lock button is on. Newer units add arrow codes that separate a blocked beam from a cut or reversed wire. Counting the flashes and telling the technician the make helps identify the cause before the visit.

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.
In a mature neighbourhood the garage door is often the single largest feature of the front elevation, so keeping the original look matters. Modern insulated doors come in raised-panel and carriage styles that echo the older designs while running on today's torsion hardware.
23%
Single-detached houses make up about 23% of homes in Toronto (2021 Census).
Where housing is mostly attached, the common garage entrance may be a rolling grille or heavy sectional door with access by fob or remote, managed by the property. We service these operators, safety edges and photo-eyes, and coordinate with management so residents keep their access throughout.
