Down, stop, back up, flashing light. That's the sensors talking, and around Omaha the cause is usually something in the beam or an eye knocked out of line.

Since 1993 every opener has shipped with two small eyes near the floor, one on each side of the opening. One sends a beam, the other watches for it, and the moment the beam breaks during a close the door reverses. That reflex is what keeps a door off a child or a car bumper, so it's tuned to be jumpy.
A door that won't close with a flashing light is therefore an opener doing its job on bad information, not a broken opener. The work is finding out why the eyes can't see each other.
Those three states cover nearly every call. They also tell us what to put on the truck if you end up phoning.
Work down the list; most doors are closing again by the second item.
There is one built-in override: hold the wall button down, continuously, until the door is fully closed. Remotes won't do it; only the wall control. It exists for exactly this night.
Don't tape the eyes together on a shelf. It fools the opener and removes the only thing stopping the door landing on someone. Hold-to-close tonight, technician tomorrow.
Steady LEDs and a clear beam but the door still reverses means the opener has a different complaint. Reversing right at the floor is the down-limit set a touch too far. Reversing part-way, with a door that's heavy to lift by hand, is a spring that has lost tension tripping the force setting. Adjust the first; stop using the opener until the second is fixed.
Cold-weather-only reversing is the same thing: Extreme continental swings, the door stiffens, the force setting trips.
Eyes do die: water in the lens, a mower strike, a board that gives up. A matched pair for Chamberlain, LiftMaster or Genie is stock on the truck and takes about twenty minutes to install and align. They don't cross brands or generations; the label on the motor unit tells us which pair.
Damaged wiring gets rerun with clips instead of staples, which is why it doesn't come back.
The brackets matter as much as the eyes. Both sensors should sit at the same height, a few inches off the floor, and a bracket that has been bent by a car bumper will keep drifting out of line however often it's reset. If the same eye needs realigning every few weeks, the bracket is the fault, and it's replaced on the visit.
Beam, lenses, alignment, wiring, in that order. A cloudy or dead eye gets a new pair. Before leaving, the technician disconnects the opener and lifts the door by hand, because reversing doors often have a spring problem hiding behind the sensor one.

Short visit, usually. The long ones are the doors that were out of balance for a year.
The opener is broken. The opener is fine; it's refusing to close on what looks like an obstruction. Fix what the sensors see and the opener behaves.
Just bypass the sensors. Don't. Hold the wall button to close it tonight, and get the eyes working tomorrow. A door without working sensors is the door that comes down on something.
New sensors mean a new opener. No. Sensors are a matched pair that plugs into the existing unit. Twenty minutes.
Usually neither. The dark one is the receiver and it goes dark when it can't see the sender: alignment, dirt or something in the way. Fix those first; replace only if it stays dark with a clear beam.
That's not the sensors. If the wall button works normally without holding it, the remote has a battery or pairing problem. If it only works when held, the sensors are the cause.
Yes, if you're comfortable with low-voltage wiring and can match the brand and generation. If not, it's a short visit and we bring the right pair.
Sun in the receiving eye. Shade it with a short hood, or swap the two sensors so the receiver faces the other way.
Free, across Douglas County. If the sensors need replacing you hear it before anything is done.
Usually, yes. A door stuck open gets priority on the schedule.
