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
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 goesSomeone backed the car in a little too far, a bin or a bicycle brushed the track, and since then the door starts to close and comes back up. One sensor now sits at a slightly different angle from the other.

How the visit goes
- 1
Ruling out sun, frost and reflections
A sensor that misbehaves on a timetable is usually being blinded rather than broken. The technician notes which way the door faces, where the low sun reaches the floor in the morning and late afternoon, and whether a receiving lens looks into that light or into a reflection off a parked car, a white wall or fresh snow. Lenses are checked for frost, condensation and a film of salt, common in an unheated garage. A hand cupped over the receiving eye while the light is watched is a simple test: if the indicator settles when the eye is shaded, the fix is a side swap or a small hood rather than new parts.

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.

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
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
Number of doors
Each opener has its own sensor pair and wire run, so a double garage with two doors is two sets of checks, two possible pairs and two rounds of testing, quoted per door.

An opener without a sensor circuit
Where the operator predates monitored sensors and cannot accept a pair, the quote changes shape into a modern operator with its own sensors, which is discussed as a separate decision rather than folded in.

Photo-Eye Sensor Alignment or Replacement: questions
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.
The opener light blinks when I press close. Is that the sensors?
Very often, yes. A blinking bulb after a close command is the opener reporting that its sensor circuit is unhappy, and the count of blinks is the message: one common family uses ten flashes for the sensors, while a short two-flash pattern usually means the wall control's lock button is on. Newer units add arrow codes that separate a blocked beam from a cut or reversed wire. Counting the flashes and telling the technician the make helps identify the cause before the visit.
What do the small lights on the sensors mean?
Arrangement varies by model: most pairs carry an indicator on each side, in differing colours for sender and receiver, though some older pairs light only the receiver, so check the maker's chart. A receiving light that is dark or flickering means the beam is not landing on it, so the pair needs aligning or something is in the way. Both lights dark means the pair has no power, which points to the wire or the terminals at the head unit. Steady lights on both sides mean a healthy system.

What the census means at the door
47%
Homes of every age. About 47% of homes in Tiny were built in 1980 or earlier, according to the 2021 Census.
A mixed housing stock means some doors are on their original openers without photo-eyes while others have modern units with apps and keypads. We handle both: upgrading the older ones for safety and quietness and adjusting or expanding the newer ones as the household grows.
97%
Mostly houses. Single-detached houses make up about 97% of homes in Tiny (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.
