- The call
- After 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.

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.

Scene 1
The two sensors have to sit at the same height, level, and facing each other squarely, no higher than about 15 cm (6 in) above the floor so the beam catches a small child or a pet. The technician measures both sides, because a bracket that has slipped a couple of centimetres down a track leg is enough to lose the beam. Each bracket is checked for bends from a bumper or a bin, for loose carriage bolts or wing nuts, and for rust where salt slush has sat against it for winters on end. A bracket screwed to a wall or the floor is checked for anchors that have worked loose.
Scene 2
No sensor job is finished on a steady light alone. The door is closed from the wall control and from a remote, and while it is on its way down an object is passed through the beam; the door must stop and return to fully open. Then a 2x4 is laid flat on the floor under the centre of the door and the door is closed onto it; it must reverse on contact. Both are repeated, the opener's diagnostic light is confirmed clear, and any app or hub reporting a sensor code is refreshed. The customer watches the tests so the normal behaviour is seen, not described.
Scene 3
The wire between the head unit and the sensors has been secured along the ceiling and walls, clipped clear of the track and, where it was exposed, run inside a protective channel. Two things keep it that way. First, when anything is fastened to those walls or that ceiling, from shelving to a bike hook to drywall, look for the thin wire before driving a screw or a staple. Second, if mice have been in the garage, a chewed wire is a common sign, so a dark sensor light after a sighting is worth a look at the run. Either way, the sensor lights will tell you the moment the circuit is open.

FeesSame any hour
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.
Questions first: what the door does, when it began, what changed. Then the beam path is cleared, the sensor lights are read, the opener's flash code is counted, and the brackets and heights are measured. If the signs point to the circuit, the wire is traced and tested with a meter. The cause is fixed, whether that is alignment, brackets, wire, a shade or a new pair, and the visit closes with the beam test and the contact reversal test.
Alignment, cleaning and a bracket adjustment are done inside an hour on most doors, including the two tests at the end. Replacing the pair adds a little for wiring and setup. Re-running the wire all the way from the motor to both sensors is the part that stretches a visit, especially where the wire is behind a finished ceiling or the garage is full. Having the floor by the door clear before arrival helps.
