The door goes up perfectly. Coming down is the trouble: partway to the floor it stops, climbs back to the top, and the light on the opener blinks at you.
Garage door opener diagnosis is a fault-finding visit with a fixed order of tests. The technician confirms power at the ceiling receptacle, tries each control on its own, checks the safety sensors and their indicator lights, examines the drive train from motor to trolley, and reads any flash code the unit is showing. Only then is a part named, because a dozen different faults look identical from the driveway and guessing at the part costs you a second visit. When the cause is a small component, the repair is made while the technician is there; when it is not, you get a clear account of what comes next.

Scene 1
With the door fully closed, the technician pulls the emergency release and lifts the door by hand. A healthy door rises smoothly with modest effort, holds still about a metre off the floor, and stays up when fully open. If it is heavy, drifts down, or stays put only at the top, the springs are tired or broken and the opener has been doing work it was never sized for. Tracks, rollers, hinges, cables and drums are looked over at the same time. This check comes before any powered testing, because a door in this state is corrected on the door side first, by someone with the tools for tensioned hardware.
Scene 2
When the by-hand check shows the door is heavy, drifting or binding, the work order changes. The opener is left disconnected and the door side is corrected first: worn rollers replaced, dry hinges and rollers lubricated, loose track brackets tightened, a dropped header bracket re-secured, and spring or cable faults handed to the tensioned-hardware work they require. Only when the door lifts and holds by hand is the trolley re-engaged and the opener tested again. Very often the opener that seemed faulty runs perfectly once it is moving a balanced door, and the repair becomes lighter and longer-lived than any change made at the motor.
Scene 3
You leave knowing a short check that catches most opener trouble early. Once a month, with the door open, lay a piece of 2x4 flat on the floor under the middle of the door and press close; the door should touch it and go straight back up. Then close the door again and pass a broom handle through the sensor beam near the floor; the door should stop and reverse. Watch the sensor lights stay steady. If either test fails, stop using the opener and book a visit. These are the same tests the technician just performed, and they are all the standard asks of a working unit.

They are a diagnostic code. On openers made in roughly the past fifteen years, the head unit flashes its lights, or a pair of up and down arrows, in a counted pattern such as one flash then five. Each pattern corresponds to a fault family on the maker's chart for that model: sensor circuit obstructed or open, motor commanded but not moving, more force than allowed. The technician reads the pattern, then confirms it by hand, since one fault can imitate another.
Three things account for most of these. The wall control has been put into lock mode, sometimes by a child or a visitor, which blocks all remotes until it is released. The opener's memory was cleared, usually by someone pressing the learn button while trying to program a new remote, so every remote needs programming again. Or the receiver in the head unit has failed. The first two are simple settings; the third is a part.
Through the house if the garage connects to it, or through a side door. Many doors also have an outside keyed emergency release, a small keyed cylinder that pulls the trolley free so the door lifts by hand from outside. If yours does not have one, the technician can fit a keyed release kit as part of the visit so there is a safe way in next time; until then, an alternate entrance is used and the diagnosis proceeds once inside.
