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
Springs are sized to a door's weight, so the technician asks what has changed since the door was installed. Insulated panels fitted over the original skins, a section replaced after a bump, a row of windows, a heavier bottom seal or decorative hardware all add weight, and even a fresh coat of paint on a wood door counts. Where the history is uncertain, the door can be weighed with the springs relaxed, using a scale under the bottom section. That figure tells the technician whether the existing springs can be adjusted to carry the door or whether the door has outgrown them and needs a different spring specification.
Scene 2
If one corner of the door sat high, that is corrected before the final tension is set. The technician releases the spring tension enough to take the load off the drums, loosens the set screws on the drum on the low side, takes up or lets out cable until the door is level, and locks the drum again with the cable seated snugly in its groove. The bottom of the door is checked against the floor along its whole width, and both drums are confirmed to show the same number of wraps. Only then is the spring tension brought back up, because tension applied to a crooked door simply loads one side more.
Scene 3
You will now know what the door feels like when it is right, which makes small changes easy to spot. A door that begins to close with a heavier thud, an opener that pauses at the top or hums a little longer, a gap appearing under one corner, or a door that no longer quite stays fully open when released are all early signs. Cold weather can make the door feel a little heavier for a few weeks without anything being wrong. But a door that stalls, races or no longer passes its balance check is telling you to stop using it and book an inspection promptly rather than waiting out the season, since the cause is not always minor.

The inspection decides, and looks past appearance alone. A spring can look sound, with tight, evenly spaced coils, no rust pitting and no gap, and still be the wrong specification for the door or nearing the end of its service life. The technician checks the spring's specification against the door's weight and history: a spring that checks out is wound and left in service, while one that is undersized, stretched, corroded or close to its cycle life is better replaced. Either path ends in a balanced door.
During a power cut the door is often released and moved by hand for the first time in years, and what people discover is a door that had already grown heavy while the opener quietly covered for it. The outage did not change the springs; it revealed them. A balance check confirms what the door weighs against what the springs give, and resets them to match.
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.
