For a few days there was a grinding sound whenever the door started moving. Now the motor spins freely and the door stays exactly where it is.
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
The photo-eye sensors are inspected together with their wiring. Each sensor carries a small indicator; a steady light on both means the beam is aligned, while a flicker, a dark light or one that goes out when the bracket is nudged points to misalignment, a loose mount or a damaged wire. The technician sights along the beam, looks for obstructions, cobwebs, frost and low sun on the receiving lens, checks that the sensors sit no higher than about fifteen centimetres off the floor, and traces the wire back to the head unit for staples, kinks and chew marks. Sensor faults are the single commonest reason a door refuses to close.
Scene 2
Photo eyes are brought back into service by fixing what actually broke. A bent bracket is straightened and re-secured so the two lenses face each other at the same height; dirty or frosted lenses are cleaned; a receiving eye blinded by low winter sun gets a shade, or the pair is swapped side to side. Wire that has been stapled through, chewed or pulled from its terminals is re-run with fresh bell wire, clipped clear of the track. When a sensor's electronics have failed, the pair is replaced together with units made for that opener, then the beam test is repeated to prove the circuit closes and the door reverses.
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.

When the cause is a common part carried on the truck, yes: capacitors, gear kits, sensor pairs, trolleys, wall controls, remotes and wiring are typical. When the part is specific to an older model and has to be ordered, or when the diagnosis finds a spring or cable problem that needs its own appointment, the door is left safe and the next step is agreed with you before the technician leaves.
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.
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.
