Photo-Eye Sensor Alignment or Replacement in Riverdale
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
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 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
Following the wire home
When the lights or the code point to the circuit, the low-voltage wire is followed from each sensor to the head unit. The technician looks for staples driven through the insulation, wire pinched behind a track bracket, sections chewed by mice, cuts where shelving or drywall screws went in, splices that have corroded, and terminals at the head unit that are loose or connected the wrong way round. A meter confirms continuity and polarity rather than guessing. Where the wire disappears into a finished ceiling, the readings at each end tell whether the hidden section is sound or whether a fresh run is the tidier answer.

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.

A record of the work
You have a short written note of what was done: the opener make and model, what the diagnostic code and the sensor lights showed on arrival, whether the fault was alignment, wiring, sun or a worn sensor, what was replaced and where the new parts sit. It records the height the sensors were set at and that both tests were passed with you watching. That note is useful for a home inspection, for the next technician, and for you, because it shows what normal looks like on this door so a future change is easy to describe over the phone.

What affects the quote
- 1
Type of kit
Some replacement kits contain only the two sensors with connectors, while others include brackets and a full length of wire. The kit that suits the opener and the state of the existing hardware is what is quoted.
- 2
Force and travel adjustment alongside
If the reversing turns out to involve a travel limit set long or a force setting made in summer, adjusting and re-testing those settings is included as a small extra step.

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.
Same fees day, night or weekend.
Photo-Eye Sensor Alignment or Replacement: questions
How do I test the sensors each month?
Start the door closing and, while it is moving, swing a broom handle through the beam low across the opening; the door should halt and travel back up. Next, put a 2x4 flat beneath the door's centre and run the door onto it; it should back off as soon as it touches. If either test fails, close the door first if you can, use it by hand with the manual release, and book a visit; do not release it if it feels heavy.
What can I check myself before calling?
Three things, all safe. Look along the floor between the sensors for anything in the path, including snow, leaves or a cobweb across a lens. Look at the two sensor lights and note whether one is dark or flickering, or both are dark. Press close and count the flashes of the opener light. If moving an object or wiping a lens brings the receiving light back on steadily, the door may close normally again; if not, those observations make the visit shorter.
Do I need to be home for the work?
It helps. The technician needs access to the garage and the head unit, and the visit ends with a demonstration of the sensor lights and the two tests so you know what normal looks like. If you cannot be there, an adult who can open the garage is enough, and the written note left afterwards records what was found and changed. Having the strip of floor beside the door clear before arrival saves time either way.

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.
