- The call
- Since shelving went up along the garage wall, the door will not close and both sensor lights are dead. A screw or staple may have gone through the thin wire that runs from the opener to the sensors.
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
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 goes
Scene 1
Following the wire home
When the lights or the code point to the circuit, the low-voltage wire is followed from each sensor to the head unit. The technician looks for staples driven through the insulation, wire pinched behind a track bracket, sections chewed by mice, cuts where shelving or drywall screws went in, splices that have corroded, and terminals at the head unit that are loose or connected the wrong way round. A meter confirms continuity and polarity rather than guessing. Where the wire disappears into a finished ceiling, the readings at each end tell whether the hidden section is sound or whether a fresh run is the tidier answer.
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
The monthly beam test
The habit worth keeping takes about a minute. Once a month, with the door open, press close on the wall control and, as it moves down, pass a broom handle through the beam near the floor. The door should stop and climb back to fully open. Then lay a 2x4 flat under the middle of the door and close onto it; the door should touch it and reverse. If either test fails, stop using the opener; close the door first if it is not already closed, then use the manual release, and get help moving it by hand if it feels heavy or will not hold. A door that passes both tests is doing its job.

What shapes the quoteDynes Garage Door Experts
- 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.
- Type of kit
- Some replacement kits contain only the two sensors with connectors, while others include brackets and a full length of wire. The kit that suits the opener and the state of the existing hardware is what is quoted.
- 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.

The questions that come up
Is it all right to keep using the door until the visit?
Use the door in a way that keeps you in control. If the opener closes only while the wall button is held, do that only while you can see the whole doorway and nobody is near it. Otherwise close the door first if you can, then move it by hand with the manual release, and get help if it feels heavy or binds. Keep children and pets clear during any test. A door that reverses is being cautious on your behalf.
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.
How should I clean the lenses?
Gently, with a soft dry or lightly damp cloth, the way you would clean eyeglasses. Never scrape a lens or use a solvent, since a scratched or clouded lens scatters the beam. Wipe both sensors, then check that the receiving light comes on steadily. If a lens frosts on cold mornings, give it a few minutes to clear or dry it with a cloth. A quarterly wipe keeps dust, cobwebs and salt film from building up.

2021 census: what it means at the door
Every square is one home in a hundred.
- 47 in 100 homes · mixed ages
- 50 in 100 homes · mixed housing
- About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.Mixed neighbourhoods often include renovated older houses with a new facade and a garage door that no longer suits it. Choosing a door that ties the renovation together, then installing it plumb and balanced in an older opening, is work we do regularly and enjoy.
- Single-detached houses make up about 50% of homes in Burlington (2021 Census).A mixed neighbourhood is where weatherproofing varies most. A detached garage with an old, uneven apron needs a thicker bottom seal; a newer townhouse door mostly needs a cracked section of seal replaced. We look at how each door meets its floor and fit what closes the gap.
