Torsion spring replacement is really a service on the whole balance system. The spring sits on a shaft that turns in a centre bearing and two end bearings, drives a pair of cable drums, and lifts the door through two steel cables. With the shaft out for the new spring, the technician inspects each of these parts, replaces bearings that grind or wobble, checks cables for fraying at the bottom brackets and confirms the drums are seated. Refreshing worn pieces at the same time means the new spring works on smooth hardware and the door runs true.

Scene 1
The spring is one part of a chain, so the check follows that chain from the shaft outward. The centre bearing and the end bearings are turned by hand to feel for roughness or wobble. Cable drums are inspected for cracked flanges and worn grooves, and lift cables are examined along their length and at the bottom brackets, where fraying and rust usually start. Bottom brackets and their fasteners are looked at for corrosion, and the shaft is checked for straightness. Findings here decide whether the visit is a spring swap alone or a spring plus a few tired companions.
Scene 2
With the door balanced, the opener comes back into service. The trolley is re-engaged, power is restored and the door is run open and closed under motor. Travel limits are adjusted so the door seals at the floor and stops at the right height, and force settings are set to the light load a balanced door presents. The technician then places an object flat on the floor in the door's path and confirms the door reverses on contact, and passes a hand through the photo-eye beam to confirm the door reverses again. These checks close the visit on a working, safe system.
Scene 3
The clearest change is in your hands: with the opener released, the door lifts with light, even effort and holds its position at mid-height instead of sliding down. That is what a balanced counterweight feels like. The door closes softly at the floor and rises without hesitation, and the opener runs with a calmer sound because it is guiding the door rather than hauling it. You can test this yourself any time by pulling the release cord with the door closed and lifting to waist height; a door that stays put is a door in balance.

The kindest thing for the door is to leave it where it is and use another entrance. An opener is designed to move a door the springs have already made light; asking it to lift a full-weight door strains the trolley and gear drive and can crease the top section. Keeping the door still and clear of people until the spring is replaced protects the rest of the system from extra repairs.
On a two-spring door, one intact spring keeps pulling on its side while the broken side goes slack, so the door lifts unevenly and a cable can jump its drum. The technician levels the door, reseats the cables in their drum grooves and evens the tension after the new spring is fitted. Rollers and track are checked for damage from the crooked travel so the door runs square again.
Balance means the spring is holding almost exactly the door's weight, so the door neither flies up nor slams down and the opener only guides it. It is tested by releasing the opener, lifting the door to about waist height and letting go: a balanced door stays there. The technician fine-tunes in quarter turns of the spring until the door holds at several heights and travels evenly on both sides.

On-site assessment
The door drops the last stretch to the floor rather than settling, and when you stop it halfway by hand it slides down instead of staying put.
