You pulled the red cord to move the door by hand during the power cut, lifted it to about waist height and let go. Instead of staying put, it kept climbing on its own and thumped into the fully open stop.
Older detached garages often have extension springs stretched along each horizontal track rather than a shaft above the door. Balancing these works differently: the tension comes from how far each spring is stretched when the door is closed, and it is set by moving the cable attachment along the track hanger or changing the hook position. Both sides are adjusted equally so the door stays level, and the containment cable running through each spring is checked at the same time. The door is opened and clamped so the springs are relaxed during the work, then tested by hand across its travel until it rests where it is left.

Garage Door Balance Adjustment · Toronto
Scene 1
The assessment begins with the opener out of the picture. The technician closes the door, pulls the red manual release so the trolley disconnects, and lifts the door by hand to about a metre, then to full height, then lets it settle. A balanced door pauses wherever it is stopped; a door that climbs on its own has too much tension, one that drops has too little, and one that is fine low down but drifts up near the top can point to drum profile, cable length, uneven section weight or the spring's own characteristics rather than one single cause. How much effort the lift takes and whether it stays fully open are noted before anything is adjusted.
Scene 2
Where the inspection found drag, it is dealt with before the springs are judged. Seized or worn rollers are swapped for new ones, one hinge at a time so the door never leaves its track. Track sections knocked out of line are eased back plumb and their brackets tightened to the jamb; a dent is dressed out or the section replaced. Hinges with play are replaced and their screws driven into sound material. The springs, hinge pins, roller stems and bearings then receive a light coat of garage-door lubricant. After this the door is lifted again, and it is common for the heaviness to be largely gone before any turns are added.
Scene 3
The difference is obvious the first time you lift the door by hand. It rises with light effort, pauses when you stop it, and stays fully open without drifting down. Closing it, the bottom seal meets the slab evenly along its length instead of thudding at one corner. Under power, the opener runs quieter because it is guiding a balanced door rather than hauling one, and it stops reversing near the floor for no reason. The door also moves at the speed of your hand, neither racing ahead nor dragging, which is exactly what the industry checklist describes as correct operation.

A broken spring is replaced rather than adjusted; there is nothing left to wind. On a two-spring door the technician normally replaces both, since the survivor has the same age and cycle count, and then balances the door on the new pair. Until the visit, leave the door closed and avoid running the opener, which is not designed to lift the door's full weight on its own.
The hand test, yes, and it is a good habit. The adjustment itself is a job for a trained technician, because the springs, cables, drums and bottom brackets are under high tension whenever the door is closed, and the industry's own guidance reserves any change to them for someone with the right bars, clamps and method. Leaving that part to the visit keeps the whole thing uneventful.
As a starting point, roughly one full turn for every foot of door height, so a seven-foot door carries a little over seven turns and an eight-foot door a little over eight. The exact figure depends on the drum size and the spring's rating, so the technician winds to the estimate and then fine-tunes by quarter turns until the hand test passes at every height.
