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.
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
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
Sometimes the diagnosis points past repair. A head unit from before photo eyes were standard, a board no longer manufactured, a motor burnt out in a housing whose gear train is also worn, or a chain-drive unit that has already had two gear kits are all cases where replacing the opener serves you better than another patch. The technician sets out what was found, why repair is a poor fit, and what a modern unit offers: a belt or direct drive for quiet, battery backup for outages, and the safety features the standard requires. The choice remains yours, and the door is left safe in the meantime.
Scene 3
Before the technician leaves, the door is run from each control you own: the wall console, each remote, the keypad and any phone connection. You watch it open fully, close to a gentle seal and stop in the right places. The opener light and indicator are explained so you know what normal looks like, and any code that appeared during the diagnosis is shown cleared. You also see the reversal tests done in front of you, so you know the door will back off a 2x4 and stop for a beam interruption. Watching the system pass gives you confidence that the repair addressed the real cause.

By separating them. With the door closed, the emergency release is pulled so the opener is out of the picture, and the door is lifted by hand. A balanced door rises without strain, hangs where you leave it around waist height and stays open at the top. If it does, the opener is at fault. If it is heavy, drifts or binds, the door is the cause and the opener was only reporting the strain. This one check prevents a great many wrong repairs.
Rollers, hinges, bearings and springs benefit from a garage door lubricant once or twice a year. The chain, belt or screw-drive rail is a separate question, since each drive type calls for its own product and schedule from the opener's manual rather than one rule for every unit. The track itself should stay clean and dry, because lubricant there collects grit and makes rollers slide instead of turning. The technician can point out the spots on your door at the end of the visit.
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.
