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
The sensors are only as good as the thin two-conductor wire that links them to the opener. It runs from the low-voltage terminals on the head unit along the ceiling and down each wall to the floor, stapled as it goes, and it is easily pierced, cut during renovations, chewed, or pulled loose at the terminals. When both sensor lights are dark, or the opener's code says the circuit is open or reversed, the technician tests the run end to end, repairs the damaged section or replaces the whole run, checks polarity at the terminals, and clips the new wire clear of the track.
How the visit goesAfter 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.

How the visit goes
- 1
Making sure it is the sensors and not the door
A door that reverses on the way down has two possible reasons, and only one of them lives at the floor. If the door touches something, including a bottom seal frozen to the slab, a travel limit set slightly long or a stiff door in cold weather, the force setting sends it back up. That looks like a sensor fault from the driveway but calls for a different fix. The technician checks whether the door reverses before it moves or after it meets resistance, watches the sensor lights during the cycle, and tries the door with the beam deliberately shaded. The answer decides whether the work stays with the sensors or moves to the settings.

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.

Winter habits
In the cold months the sensors ask for a little attention. On frosty mornings give a misted lens a moment to clear rather than pressing close over and over, and wipe it with a dry cloth if it does not. Keep salt slush from building up against the brackets, since salt is what corrodes the mounts and terminals over time. Clear snow from just inside the door before closing it, and if the bottom seal has frozen to the slab, free it by hand rather than asking the opener to pull it loose. If the door closes at noon but not at nine, mention it; the low sun may be reaching the receiving eye and a shade sorts that out.

What affects the quote
- 1
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.
- 2
Alignment or replacement
Cleaning, re-aiming and refastening the existing pair is the smaller job. Fitting a new matched sending and receiving pair is the larger one, and the diagnosis at the door decides which applies before the quote is settled.

Protecting exposed wire
On a wall where the wire runs in the open, a slim protective channel or a re-route higher along the wall keeps bins, bikes and mice away from it, and is quoted as its own line.

Photo-Eye Sensor Alignment or Replacement: questions
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.
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.
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.

What the census means at the door
51%
Older homes. About 51% of homes in Clearview were built in 1980 or earlier, according to the 2021 Census.
Extension springs are common on older doors, and they should carry a safety cable through the middle so a broken spring is held rather than flung. Adding those cables is a small job the technician checks for and offers on any older door he services.
90%
Mostly houses. Single-detached houses make up about 90% of homes in Clearview (2021 Census).
Family homes with their own garage tend to use it as the everyday entrance, so the door sees many cycles a week and the auto-reverse and photo-eyes matter for children and pets. We test both on every visit and set the force so the door stops on a light touch.
