- 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.
In plain words
Your opener has been trying to tell you what is wrong. The head unit flashes its light a set number of times, or blinks a pattern on its up and down arrows, and each pattern maps to a cause on the maker's chart: beam blocked or misaligned, wire cut or disconnected, wires reversed or shorted. Down at the floor, many sensor pairs carry an indicator on each side, though some older pairs light only the receiver; check that model's chart, since a receiving light going out or flickering usually points to alignment. The technician reads both sets of signals first, which is why the repair usually takes one visit.

How the visit goes
Scene 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.
Scene 2
Repairing the wire run
Damaged wire is dealt with in whole sections rather than patched at a single point. A pierced or chewed length is cut back to sound insulation and either spliced with proper connectors or, more often, replaced from the sensor to the nearest good junction. Where the run has failed in more than one place, a fresh two-conductor wire is stapled from the motor housing across the ceiling and down both sides of the opening, kept clear of the track, hinges and the door's travel. At the head unit the pair is landed on the correct low-voltage terminals with polarity confirmed, and the sensor lights are checked before anything is tidied.
Scene 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 shapes the quoteMount Nemo Door Specialists
- Sun and reflection remedies
- Swapping the sensors side to side is a small addition when the wiring reaches. Fitting a shade, or extending the wire so the receiver can move, is a little more and is listed on its own.
- 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.
- 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.

Answers in plain language
What tests are done before the technician leaves?
Two, and you are invited to watch. With the door closing, an object is passed through the beam and the door has to halt and climb back to the top. A 2x4 laid flat beneath the door's centre comes next; closing onto it must make the door back off on contact. The door is also run from the wall control and a remote, the opener's warning flashes are confirmed gone, and both sensor lights are shown steady.
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.
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.
- 61 in 100 homes · older homes
- 56 in 100 homes · mixed housing
- About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Where houses are older, the garage often sits beside the house rather than beneath a bedroom, so noise is a smaller concern and durability a larger one. Heavy-duty rollers, a properly sized torsion spring and cold-rated lubricant make an old door dependable for years.
- Single-detached houses make up about 56% of homes in Hamilton (2021 Census).Mixed housing brings mixed garage use: workshops and storage in the detached homes, everyday parking and a tight squeeze in the attached ones. Sealed rollers and protected sensors suit the busy workshop door; a quiet opener and a well-balanced door suit the townhouse.

Since shelving went up along the garage wall, the door will not close and both sensor lights are dead.
