  1. Never bypass, tape over or relocate the sensors to make a door close; a door that reverses is reporting something worth fixing.

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.

Sound familiar?

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.

How the visit goes

  1. 1

    Counting the opener's flashes

    The head unit has its own way of reporting a sensor problem. Many openers flash the light bulb a fixed number of times when close is pressed and the beam is not satisfied, and newer units blink a code on their up and down arrows that separates a blocked or misaligned beam from a cut wire, a disconnected pair or reversed wiring. The technician reads the model off the label, counts the pattern and matches it to the maker's chart. This is what keeps the visit efficient: a code that says the circuit is open sends the work to the wiring, while a code that says obstructed or misaligned sends it to the brackets.

  2. 2

    Fitting a matched sensor pair

    When a sensor has failed, the replacement is chosen for the opener rather than from a shelf of lookalikes. The technician confirms the make and generation from the head unit label, because sensors from one era are not always recognised by a board from another. The new sending and receiving sensors are mounted on the existing or new brackets at matched heights, wired with the connectors supplied, and brought up until both indicators glow steadily. Universal pairs exist for some operators and are used where they are documented to suit that model; where the opener is old enough that no compatible pair is made, the conversation moves to a modern operator.

  3. 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 affects the quote

  1. 1

    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.

  2. 2

    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.

  3. 3

    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.

Advice · (289) 807-2460

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.

What can I check myself before calling?

Three things, all safe. Look along the floor between the sensors for anything in the path, including snow, leaves or a cobweb across a lens. Look at the two sensor lights and note whether one is dark or flickering, or both are dark. Press close and count the flashes of the opener light. If moving an object or wiping a lens brings the receiving light back on steadily, the door may close normally again; if not, those observations make the visit shorter.

Do I need to be home for the work?

It helps. The technician needs access to the garage and the head unit, and the visit ends with a demonstration of the sensor lights and the two tests so you know what normal looks like. If you cannot be there, an adult who can open the garage is enough, and the written note left afterwards records what was found and changed. Having the strip of floor beside the door clear before arrival saves time either way.

What the census means at the door

58%

Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.

Older garages tend to have lower headroom and narrower single openings, so replacement doors and openers are chosen to fit the space rather than the other way round. Measuring the header, side room and ceiling depth is the first step on every one of these visits.

23%

Single-detached houses make up about 23% of homes in Toronto (2021 Census).

In attached housing, a resident's remote or fob may open both their own door and a shared gate, and lost devices are a real security concern. We clear old codes from the operator, program replacements, and explain to management how to keep the access list current.
