You press the remote from the driveway and hear the motor hum overhead, a steady drone with no movement behind it. The door stays shut.
Think of a command travelling through the system. Your thumb presses a button; the radio signal reaches the receiver; the logic board decides to move; the motor turns; a gear drives a chain, belt or screw; the trolley pulls the arm; the arm moves the door. A fault at any link produces the same result from where you stand: nothing happens. Diagnosis walks that chain in order and finds the broken link, whether it is a flat remote battery at the start or a stripped gear in the middle. Working from one end keeps the fix small and the explanation simple.

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
Control faults are corrected at the control that failed. A wall console in lock mode is released by holding its lock button until the indicator stops flashing. Remotes get fresh batteries of the type the maker specifies, then are reprogrammed to the head unit with its learn button if the memory was cleared. Range problems are traced to interference, most often from certain LED bulbs in the opener's own sockets, and cured by swapping bulbs or extending the antenna wire. A wall control with a shorted or pinched cable gets new low-voltage wire; a failed receiver or wall control is replaced with one compatible with the opener's frequency and coding.
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.

Two usual reasons. The travel limit is set a fraction too long, so the door reaches the slab, meets it harder than expected and interprets that as an obstruction. Or the bottom seal has stiffened or frozen and the last few centimetres take more force than the setting allows. Both are adjusted after the door is checked for balance, and the fix is confirmed by closing the door several times and running the contact reversal test.
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.
Not usually. Outages and the surges that ride along with them commonly trip a breaker or a ground-fault receptacle, blow the small fuse on the board, or knock out the transformer, and each of those is a modest repair. A surge that damages the logic board itself is the more serious case, and whether that board is replaced or the unit retired depends on the model's age and part availability. The diagnosis tells you which case you have.
