Nothing. No light, no click, no hum from the unit on the ceiling.
What you get from the visit is more than a working door. You get told, in plain words, what was wrong and why it happened: a gear that had run dry for years, a sensor knocked out of line by a snow shovel, a wall control left in lock mode by a visiting grandchild. Small repairs are done on the spot, settings are recorded, and the door is demonstrated on every control you own. You also learn the short monthly test that catches most opener problems before they strand a car, so the next fault is one you notice while it is still small.

Scene 1
Finally the settings are checked against what the door actually does. Travel limits decide where the door stops at the top and how firmly it meets the floor; a limit set slightly long makes the door hit the slab, sense an obstruction and pop back open. Force settings decide how much resistance the opener tolerates before reversing, and these drift, or get turned up to hide a stiff door. Both are read, the door is run through full cycles, and the contact reversal test with a 2x4 and the beam-interruption test are performed. Any setting that only passes because force is cranked high is treated as a symptom.
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
After a winter diagnosis the door is set up for the season rather than for the day. The bottom seal has been freed and, if it was tearing, replaced, with a light silicone wipe so it releases from the slab. Moving parts carry a low-temperature lubricant. The photo eyes have been cleaned and, where low sun was blinding one, shaded or swapped side to side. Force has been set for a cold, stiff door without being pushed up to hide one. Keep snow and ice cleared from the threshold and the sensor lenses, and expect the door to be a shade slower on the coldest mornings.

Look for the simple things: is the opener plugged in and its light working, has the wall control's lock indicator started blinking, does another remote work, is anything sitting in the path of the sensors, and are the little sensor lights steady. Note what the motor does when you press a button. Do not try to lift a door that is stuck if a spring looks broken. Whatever you find, tell the technician; it shortens the diagnosis.
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.
A door that opens with nobody pressing anything is usually being told to by a fault in its wiring or a control. A pinched or stapled wire to the wall control can short intermittently and act like a button press; a stuck button on a remote left in a coat pocket does the same; and a neighbour's remote on an old fixed-code opener can occasionally trigger it. The technician isolates each control in turn until the phantom command stops.
