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.
An opener is designed to move a door that is already balanced, and every safety feature in it assumes that. The force it applies is limited so the door will stop and reverse when it meets something, and that limit only makes sense when the door is close to weightless. When springs lose tension, the opener has to lift real weight, its motor and gears work harder, and it may reverse or stall for no obvious reason. A balance adjustment puts the weight back on the springs where it belongs, so the opener can return to the light duty it was built for and its reversing behaviour is dependable again.

Garage Door Balance Adjustment · Markham
Scene 1
Adjustment only makes sense on a spring that is sound, so each one is examined closely. On a torsion system the technician looks for a gap in the coil, rust pitting, uneven coil spacing and a cone that has slipped on the shaft, and measures the wire size, inside diameter and length to confirm the spring suits the door's weight. On extension springs the check is for stretched or opened coils, a broken end loop and the presence of a containment cable. A spring that has simply lost a little tension can be wound up; one that is undersized or near the end of its cycle life is explained and offered as a replacement instead.
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
Part of the visit's value is knowing where the springs stand. If they were adjusted and left in place, you will have been told roughly how much life they appear to have and what signs mark their end: a door that grows heavy again within a season, a coil gap, or rust flaking from the wire. If they were replaced, the door starts a new cycle count and the note by the opener says when they went in. Either way, you can plan the next spring work on your own schedule rather than on the morning the car needs to leave and the door refuses to lift.
What shapes the quoteMount Joy Door & Opener Co.
FeesSame any hour
A straightforward tension adjustment on a sound door is generally about an hour, including the inspection, the hand tests and the opener checks at the end. Resetting cables to level the door, replacing rollers to remove friction, or moving to a spring replacement adds time. The technician will tell you what the inspection found and how the visit is shaping up before the work continues.
The opener is built to move a balanced door, and its force limit is what makes it stop and reverse on contact. Raising that limit to lift a heavy door pushes the safety behaviour out of its intended range and works the motor and gears hard. The sound order is to balance the door first, then set the opener to suit it. Both are done in the same visit.
Yes, and installers will usually insist on it. A new opener is set up against the door it meets on the day, so its travel and force settings are only right if the door is already balanced. Fitting a new motor to a heavy door shortens the motor's life and puts the safety reversal out of range. Balancing first means the new opener starts life doing the light work it was designed for.
