Photo-Eye Sensor Alignment or Replacement in Tyandaga
The 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.

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 goesOn bright mornings the door will not close, then by lunchtime it behaves itself. The garage faces the low sun, and the light reaches straight across the floor to one of the little black sensors.

How the visit goes
- 1
Brackets and height on both sides
The two sensors have to sit at the same height, level, and facing each other squarely, no higher than about 15 cm (6 in) above the floor so the beam catches a small child or a pet. The technician measures both sides, because a bracket that has slipped a couple of centimetres down a track leg is enough to lose the beam. Each bracket is checked for bends from a bumper or a bin, for loose carriage bolts or wing nuts, and for rust where salt slush has sat against it for winters on end. A bracket screwed to a wall or the floor is checked for anchors that have worked loose.

Fitting a matched sensor pair
When a sensor has failed, the replacement is chosen for the opener rather than from a shelf of lookalikes. The technician confirms the make and generation from the head unit label, because sensors from one era are not always recognised by a board from another. The new sending and receiving sensors are mounted on the existing or new brackets at matched heights, wired with the connectors supplied, and brought up until both indicators glow steadily. Universal pairs exist for some operators and are used where they are documented to suit that model; where the opener is old enough that no compatible pair is made, the conversation moves to a modern operator.

Two lights to glance at
You leave knowing what normal looks like at the floor. Most sensor pairs carry a small indicator on each side, often in different colours for sender and receiver, though some older pairs light only the receiver; the model's own chart tells you what steady and flickering mean. A dark or flickering light on the receiving side means the beam has been lost, usually because a bracket was bumped or something is in the path, and two dark lights mean the pair has lost power along the wire. A glance at those lights before calling anyone tells you most of what the technician would look at first, and often the fix is moving whatever is leaning on the bracket.

What affects the quote
- 1
Alignment or replacement
Cleaning, re-aiming and refastening the existing pair is the smaller job. Fitting a new matched sending and receiving pair is the larger one, and the diagnosis at the door decides which applies before the quote is settled.
- 2
Bracket condition
A bracket that can be straightened costs little time. One that is cracked, rusted through or missing is replaced, and a change from track clips to wall or floor brackets adds anchors and mounting work.

Undoing an earlier shortcut
Sensors taped together beside the motor, mismatched pairs from different generations or a bypassed circuit are put right first, which means new wire down each side and fresh brackets at the doorway.

Photo-Eye Sensor Alignment or Replacement: questions
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.
Could the door's force setting be the real reason it reverses?
Sometimes. The opener also backs up when it meets more resistance than its force setting allows: an iced seal, a limit that drives the door into the slab, rollers stiff with cold. From the driveway that looks identical to a beam problem. Timing is a clue, not proof, since a flickering beam can reverse the door partway and severe binding can trigger a force reversal right at the start; the sensor lights and diagnostic pattern settle which it is. The technician checks both so the right thing is fixed.
What tests are done before the technician leaves?
Two, and you are invited to watch. With the door closing, an object is passed through the beam and the door has to halt and climb back to the top. A 2x4 laid flat beneath the door's centre comes next; closing onto it must make the door back off on contact. The door is also run from the wall control and a remote, the opener's warning flashes are confirmed gone, and both sensor lights are shown steady.

What the census means at the door
47%
Homes of every age. About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.
Where homes of different ages sit together, the common thread is that every door eventually needs springs, rollers, seals and a balance check. What differs is the spring type and the size, so the technician measures and matches rather than fitting a standard part.
50%
A mix of homes. Single-detached houses make up about 50% of homes in Burlington (2021 Census).
A blend of housing means a blend of garages: spacious attached garages with full headroom on the detached lots, and tight tandem garages with little side room in the attached units. Openers, tracks and springs are all sized at the door rather than assumed from the street.
