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.
On a torsion door the springs sit on a shaft above the opening, and balance is set by how many turns of wind they carry. A seven-foot door typically needs a little over seven full turns; a quarter turn either way changes how the door feels. The technician clamps the door, fits winding bars into the cone, loosens the set screws, and adds or releases tension one quarter turn at a time, locking the cone again before each test. Both springs on a two-spring door are set alike so the shaft carries the load evenly. That precision is what makes the door hold wherever it is stopped.

Scene 1
Some doors that feel heavy are not short of spring tension at all; they are dragging. The technician runs a hand and an eye along the vertical and horizontal tracks for dents, misaligned joints and brackets that have pulled away from the jamb, spins each roller to find seized bearings or cracked wheels, and flexes each hinge for play or splits. Dry, worn rollers alone can add real effort to every lift. Binding at one point in the travel, rather than heaviness everywhere, is the signature of a friction problem, and correcting it first means the springs are then adjusted to the door's true weight rather than to the drag.
Scene 2
On an extension system the door is opened fully and clamped so each spring hangs slack, and the tension is changed by moving the S-hook or the cable clip to a different hole in the track hanger, or by shortening the cable at the clip. A hole further back stretches the spring more when the door closes and adds lift; a hole further forward reduces it. Both sides are moved the same amount so the door stays level, and the pulleys and containment cables are checked as the hooks are reset. The clamps come off and the door is tested by hand at several heights, then adjusted again if needed.
Scene 3
A balanced door lets the opener's safety settings stay at sensible values, and it is worth keeping them there. If the door ever starts to reverse for no reason or struggles to lift, resist the temptation to turn the force up on the motor; that hides a door that has grown heavy again and takes the entrapment protection out of its proper range. Instead, release the door and try the hand test. If it no longer holds, the springs want attention, and a balance adjustment puts the weight back on them so the opener can remain at the gentle settings it was left with.
What shapes the quoteSaugeen Door Specialists
FeesSame any hour
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.
A little, twice a year. Use a product sold for garage doors on the spring coils, hinge pins, roller stems, bearings and bracket pins, and cycle the door a few times to work it in. The tracks want a wipe, not a spray, because a slick track lets the rollers skid and gathers grit. Skip thick grease. Low friction is what lets the springs' setting hold true.
Not enough spring tension for the door's weight. Springs lose a little pull as they age through thousands of cycles, and a door gains weight when insulation, windows or a heavier seal are added. Either way the door outweighs its springs. Adding tension in measured quarter turns restores the hold, provided the springs are sound; if they are near the end of their life, new ones are the right answer.
