- The call
- On 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.
In plain words
Your opener has been trying to tell you what is wrong. The head unit flashes its light a set number of times, or blinks a pattern on its up and down arrows, and each pattern maps to a cause on the maker's chart: beam blocked or misaligned, wire cut or disconnected, wires reversed or shorted. Down at the floor, many sensor pairs carry an indicator on each side, though some older pairs light only the receiver; check that model's chart, since a receiving light going out or flickering usually points to alignment. The technician reads both sets of signals first, which is why the repair usually takes one visit.

How the visit goes
Scene 1
Reading the two small lights
Most sensor pairs carry an indicator on each side, though some older models light only the receiver, so the technician checks that model's own chart first. On most openers the sending eye shows one colour and the receiving eye another, and both should glow without a flicker. If the sending light is steady and the receiving light is dark or blinking, the beam is not landing where it should: misalignment, an obstruction or a dirty lens. If both are dark, the pair has no power, pointing up the wire to a cut, a loose terminal or reversed connections. The technician also nudges each bracket gently while watching the light; a flicker on touch means a loose mount.
Scene 2
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.
Scene 3
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 shapes the quoteFairhaven Garage Door Services
- 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.
- 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.
- 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.

What to expect, in questions
Can any sensor pair be used with my opener?
Not any, no. Sensors are matched to the opener's make and generation, and a board from one era may ignore sensors from another even when the wires fit. The technician reads the model from the head unit label and fits the pair listed for it. Some operators accept a documented universal pair, and those are used where the maker lists them as suitable; on a very old unit with no compatible pair, a modern operator is the way forward.
Will the sensors need replacing or just aligning?
Most visits end in alignment, cleaning and bracket work, because the sensors themselves are hardy. Replacement comes into it when a lens has clouded or crazed, when the housing is split or holds water, an indicator stays dark with the wiring proven good, or the pair is from a different generation than the opener and is never recognised. The technician tests before choosing, so the parts list matches what the door needs.
My opener has no sensors at all. Can they be added?
If the opener predates the entrapment-protection standard, which operators have had to meet since the mid-1990s, its board has no sensor circuit and a pair cannot simply be wired in. The positive news is that a modern operator brings the whole package: matched sensors, force reversal and a monitored circuit. The technician confirms the model first, because some units do have the terminals and simply had their sensors removed.

2021 census: what it means at the door
Every square is one home in a hundred.
- 58 in 100 homes · older homes
- 23 in 100 homes · mostly attached
- About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.Where most houses were built a generation or more ago, a good share of garage doors are still the originals: wood or early steel sections on extension springs. Those doors respond well to fresh pulleys, safety cables and a careful balance, and the technician carries the parts for them.
- Single-detached houses make up about 23% of homes in Toronto (2021 Census).Townhouses built in rows tend to have identical doors from the same builder, so when springs and openers age they do so together along the street. Owners often arrange service for several doors at once, and we can plan a single visit that covers the row.

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.
