- 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.
After a cold night the door stays open until the garage warms up. There is frost on the sensor lenses and a ridge of salty slush piled against the brackets where the snow blower was parked.
In plain words
Most sensor visits end in alignment rather than new parts. The brackets that hold the sensors ride on the door track or the wall, and they get bumped by bins, tires and shovels until the two lenses no longer look at each other. The technician resets both sensors to the same height, loosens the wing nuts, aims the pair until the receiving light holds steady, tightens everything and secures the wire. Replacement is the answer when a lens is crazed, a housing is cracked, water has got inside or the indicator stays dark with good wiring, and then a pair matched to the opener is fitted.

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
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.
Scene 3
Keeping the brackets out of harm's way
Most repeat sensor calls come from the same few habits, and they are easy to change. Keep recycling bins, bicycles, boots and the snow shovel away from the bottom of the door track on both sides. Park with a little room to spare so a bumper never meets a bracket. When you sweep or blow snow out of the garage, aim away from the sensors rather than at them. If shelving or a workbench goes in along that wall, leave the strip near the floor free. The brackets are sturdy, but they hold a precise line, and a nudge that would not bother anything else is enough to lose the beam.

What shapes the quoteArmour Heights Door Specialists
- 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.
- 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.
- Door-side findings
- A balance problem, a stiff roller or a bottom seal that needs replacing sometimes shows up during testing. Those belong to their own service and are noted and quoted separately rather than hidden in the sensor work.

Asked and answered
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.
Could the wiring be the problem rather than the sensors?
Frequently. The sensors are fed by a thin two-conductor wire from the head unit that crosses the ceiling and drops down both sides of the door, and it is pierced by staples, cut by shelving screws, chewed by mice or pulled from its terminals more often than a sensor fails. Both sensor lights dark, or an opener code for an open or reversed circuit, points to the wire. The technician tests the run with a meter and repairs or replaces the damaged section.
How long does a sensor visit take?
Alignment, cleaning and a bracket adjustment are done inside an hour on most doors, including the two tests at the end. Replacing the pair adds a little for wiring and setup. Re-running the wire all the way from the motor to both sensors is the part that stretches a visit, especially where the wire is behind a finished ceiling or the garage is full. Having the floor by the door clear before arrival helps.

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.
