- The call
- 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. It has done this every evening this week.
There are no sensors at the floor at all, or a previous owner has wired the pair together up beside the motor so the beam never crosses the doorway. A home inspector has just pointed it out.
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
Starting with the story
The first minutes are spent listening. What does the door do when close is pressed: drop and bounce, stay put, or close only while the wall button is held? Does the opener light blink, and how many times? When did it start, and what changed around then: a car bumped the track, a storm, shelving went up, the garage was reorganised, the first frost arrived? Does it happen at all hours or only on bright mornings? Those answers usually point at one of a handful of causes before a single tool comes out, and they decide whether the technician heads for the brackets, the wire or the head unit first.
Scene 2
Bringing the pair back to the doorway
Sometimes the sensors exist but have been defeated: taped face to face next to the head unit so the circuit is always satisfied and the door closes on anything. The technician separates the pair, checks that both still work, and mounts them where they belong on each side of the opening, low to the floor and facing each other. New wire is run down each side, brackets are fitted, and the alignment is set. The opener is then made to prove itself with the beam test, and the household is shown why the pair matters and how to keep it working, so the shortcut is never tempting again.
Scene 3
Wiring that stays put
The wire between the head unit and the sensors has been secured along the ceiling and walls, clipped clear of the track and, where it was exposed, run inside a protective channel. Two things keep it that way. First, when anything is fastened to those walls or that ceiling, from shelving to a bike hook to drywall, look for the thin wire before driving a screw or a staple. Second, if mice have been in the garage, a chewed wire is a common sign, so a dark sensor light after a sighting is worth a look at the run. Either way, the sensor lights will tell you the moment the circuit is open.

What shapes the quoteArmbro Heights Garage Door Pros
- 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.
- 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.
- 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.

Ask us anything
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.
How high off the floor should the sensors sit?
Low. The industry checklist expects the beam no more than roughly 15 cm (6 in) up from the floor, so that a small child, a pet or a bicycle wheel breaks it. Both sensors are set at the same measured height and level with each other, since a difference of a couple of centimetres is enough to lose the beam. Within that rule the technician can raise them a little to keep them out of the strip where slush collects.
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.

2021 census: what it means at the door
Every square is one home in a hundred.
- 23 in 100 homes · newer homes
- 53 in 100 homes · mixed housing
- About 23% of homes in Brampton were built in 1980 or earlier, according to the 2021 Census.Builder-grade hardware is common on newer doors: light rollers, thin hinges and a basic opener that met the specification on the day. Upgrading to nylon rollers, heavier hinges and a belt-drive opener turns a serviceable door into a quiet one, which matters when bedrooms sit above.
- Single-detached houses make up about 53% of homes in Brampton (2021 Census).In mixed neighbourhoods, noise matters differently from one address to the next. A detached house with a bedroom above the garage and a townhouse with a neighbour through the wall both benefit from a belt-drive opener and nylon rollers, and we explain the difference either way.
