It is a January morning and the door lifts about a hand's width, groans, and settles back down. When you pull the release and try by hand the door feels far heavier than it used to, and the bottom seal is stuck hard to the slab.
An opener is only half of the machine. The other half is the door: springs balanced so the door weighs almost nothing in your hand, rollers turning in a straight track, hinges holding the panels square. When that half slips out of tune, the opener takes the blame for straining, stalling or reversing, and a bigger motor or a higher force setting only hides the fault. A proper diagnosis disconnects the door from the operator and lifts it by hand before anything else. If it floats to shoulder height and stays there, the opener is the patient. If it drops or fights back, the door is.

Scene 1
Many openers describe their own fault. The head unit flashes its light bulbs, or an up arrow and a down arrow, in a numbered pattern, and some display a code on the wall control. The technician counts the pattern, identifies the exact model from its label, and matches the two on the manufacturer's chart: one family of codes means the sensor circuit is open or obstructed, another means the motor was told to move and nothing turned, another means the door needed more force than the limit allows. The code narrows the search; a hands-on test then confirms it, because a wiring fault can imitate a sensor fault.
Scene 2
When the fault is electrical supply, the fix is matched to the cause rather than simply reset. A tripped breaker or ground-fault device is reset and then watched through several cycles to be sure it holds; one that trips again points to a damaged cord, a wet outlet or a failing motor. A blown board fuse or a dead transformer is replaced with the part specified for the model. Surge damage after lightning often shows as a board that lights up but ignores every control, and that board is replaced where the model is still supported. New receptacles or hard wiring are referred to an electrical contractor.
Scene 3
When the diagnosis finds an opener that is safe today but not for long, you leave with a plan rather than a surprise. You know which part is wearing, what the warning signs will be, and how the decision to replace is likely to present itself. If the unit is one the industry recommends replacing, such as a head unit with no photo eyes, that is set out plainly along with what a modern belt or direct-drive unit changes: quieter running, battery backup, soft start and stop, and sensors that meet the current standard. The door is left working and safe while you decide.

Age alone is not the test; parts and safety are. The technician checks the exact model and part numbers, because even a unit from the last two decades can have a board, sensor or trolley that is no longer made. Where the parts are available, a repair is usually straightforward. Where a key part is discontinued with nothing to replace it, or the unit predates photo eyes, replacement is the sounder choice even for a small fault. The technician tells you which side of that line your unit sits on.
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.
The opener believes something is in the way. Either the photo-eye beam near the floor was broken, misaligned or blocked, or the door met more resistance than its force setting allows, often from a frozen seal, stiff rollers or a travel limit set slightly too long so the door hits the slab. The indicator light on the head unit usually tells which of the two it was, and the technician confirms it by testing rather than guessing.
