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
A door that is out of level is usually a cable story rather than a spring story. The technician checks that each cable wraps its drum in a single neat layer with the same number of wraps on both sides, that the drum set screws are tight on the shaft, and that neither cable is frayed or rusting at the bottom bracket. A tape across the bottom of the door in the closed position shows whether one corner sits high. If it does, the cables are reset on the drums so the door is level before spring tension is judged, because a crooked door binds in its track and feels heavy regardless of how the springs are wound.
Scene 2
With one winding bar seated firmly in the winding cone and a second ready, the technician loosens the cone's set screws and either adds tension by levering the bar upward or releases it by letting the bar down, always a quarter turn at a time, always with a bar in the cone. After each quarter turn the set screws are tightened onto the shaft, the clamp is removed and the door is lifted by hand to test. A door that sank now holds a little higher; a door that climbed now settles. On a two-spring door the same change is made to both springs so they share the load equally.
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.
What shapes the quoteErin Mills Garage Door Experts
FeesSame any hour
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.
Each corner hangs on its own cable, and if one cable has slipped on its drum, stretched or been wound with a different number of wraps, that corner sits at a different height. On extension doors, one spring stretched more than its partner does the same. The cables or hooks are reset so the door is level, then the tension is set. A level door also stops binding in its track.
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.
