Photo-Eye Sensor Alignment or Replacement in Collingwood
You 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.

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
Photo-eye sensor service brings back the invisible beam that runs across the bottom of your doorway and lets the opener close with confidence. A technician clears the path, checks each sensor's indicator, tests the low-voltage wiring back to the head unit, and reads the opener's own diagnostic lights to tell an obstruction from a wiring fault. Brackets are straightened and refastened, lenses cleaned, and the pair aimed at each other at the same height no higher than 15 cm off the floor. If a sensor has failed, a matched pair for that opener family goes in. The visit ends with a beam test and a contact reversal test.
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
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.

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.

A door that closes from the driveway again
The change you notice first is the ordinary one: you press the remote from the car, the door goes all the way down, and nobody has to stand in the garage holding a button. Behind that is a beam that is once more crossing the doorway at the right height, a pair of sensors that agree with each other, and an opener that is no longer flashing a warning every time you ask it to close. The door still stops and returns to open whenever the beam is broken, which is exactly what it should do, and now it does that only when something is genuinely in the way.

What affects the quote
- 1
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.
- 2
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.
- 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
Will my phone app or hub still work after the sensors are changed?
Yes. The sensors are wired to the head unit, and the app or hub simply talks to that unit, so nothing about the connection changes. What you will notice is the fault code clearing: apps that reported the sensors as obstructed or not aligned show the door as ready to close again. If an app or hub still holds an old code after the work, refreshing it or cycling the door from the app once clears it.
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 do the small lights on the sensors mean?
Arrangement varies by model: most pairs carry an indicator on each side, in differing colours for sender and receiver, though some older pairs light only the receiver, so check the maker's chart. A receiving light that is dark or flickering means the beam is not landing on it, so the pair needs aligning or something is in the way. Both lights dark means the pair has no power, which points to the wire or the terminals at the head unit. Steady lights on both sides mean a healthy system.

What the census means at the door
40%
Homes of every age. About 40% of homes in Collingwood were built in 1980 or earlier, according to the 2021 Census.
Where houses span several decades, weatherproofing needs vary: older garages with uneven aprons need thicker bottom seals, newer ones mainly need cracked seal sections replaced. The technician looks at how the door meets the floor and the jambs and fits the seal that actually closes the gap.
56%
A mix of homes. Single-detached houses make up about 56% of homes in Collingwood (2021 Census).
In areas mixing houses with townhouses and condos, a technician often works on several doors on one street, some owned outright and some looked after by management. Scheduling them together saves everyone time, and we are glad to plan a visit that covers the group.
