- The call
- 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.
In plain words
By the end of the visit you have a door that closes from every control and reverses the instant the beam is broken, a sensor pair mounted level at the right height with steady indicator lights, wiring that is secured and out of harm's way, and a written note of what was found and what was changed. The technician walks you through the two tests you can repeat monthly, points out which light is which, and leaves the opener's diagnostic chart where you can find it. It is a small job that puts a large piece of your door's protection back in service.

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
Resetting the alignment
Alignment is done with the door open and the lights in view. The technician sets both sensors to the same measured height, loosens the wing nut on the receiving side, and turns the sensor a fraction at a time until its indicator changes from dark or flickering to steady. The nut is tightened while the light is watched, because a sensor can drift as the fastener bites, and the sending side is treated the same way. Brackets are checked for play and the wire is re-clipped so it cannot tug the sensor out of line. A steady light on both sides, held through a few door cycles, is the standard.
Scene 3
If it ever reverses again
Should the door start bouncing back up in the future, you know the order to check. Look along the floor for anything in the beam. Look at the two sensor lights for a dark or flickering one. Look at whether the door backs up as soon as it starts or only after touching something, since the second points to the door's settings rather than the beam. Note whether the opener light is flashing and how many times. With those four facts the cause is usually obvious, and if a visit is needed, the technician arrives already knowing where to begin.
In the van
- Two-conductor low-voltage wire
- Multimeter
- Wire connectors
- Concrete anchors
- Wall or floor angle brackets
What shapes the quoteRouge Valley Garage Door Co.
- Winter conditions on the day
- Snow and ice packed against the brackets, a frozen bottom seal or a frozen floor where anchors must go all add a little clearing and care before the sensor work itself can start.
- 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.
- Wall or floor mounting with anchors
- Mounting into concrete or masonry rather than onto the track means drilling, anchors and sealing against water, which takes more time than clipping to the rail.

The questions that come up
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.
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 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.

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.Hardware on an older door has often been through many winters: hinges with worn pins, rollers with tired bearings, bottom brackets rusted at the floor line. Replacing these in sets restores a smooth lift and takes a surprising amount of noise out of the garage.
- Single-detached houses make up about 23% of homes in Toronto (2021 Census).In condominium communities the outward appearance of a garage door is often set by the corporation's rules, down to colour and panel style. We check what the board expects before ordering a replacement door, so the new one is approved and matches the row without a second conversation.
