Looking up at the coil above the door, you can see a clean split with a gap of several centimetres between the two halves. The rest of the spring looks fine, but the door has become almost impossible to move by hand.
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
Winding is where a spring takes on its working tension, and it is done with two solid steel bars sized to the holes in the winding cone. The technician stands to the side of the cone, inserts one bar, turns a quarter turn, inserts the second bar, and transfers the load from bar to bar so the spring is never held by less than a full bar. The number of quarter turns is counted against the door height and drum type. When the count is reached, the spring is stretched slightly toward the drum and the set screws are tightened to the shaft while the last bar still carries the load.
Scene 3
Your opener benefits as much as the door. With the spring carrying the weight again, the motor, gear drive, trolley and rail return to the light duty they were designed for, which tends to mean a longer working life and less noise. Force settings have been reset to suit a balanced door, so the safety reversal reacts to a genuine obstruction rather than to a heavy door. Once a year, repeat the simple reversal test by placing a length of wood flat on the floor in the door's path and confirming the door reverses on contact. The opener's photo-eye sensors deserve a wipe at the same time.

Low-headroom garages use a different arrangement: the spring assembly may be mounted at the rear of the horizontal tracks, or special low-headroom drums and track bring the door up with less clearance. Replacement follows the same principles, but the drums, cable routing and turn count differ. The technician identifies the system on arrival and brings hardware that suits it, so the door balances correctly in the space available.
Cold makes steel slightly less forgiving and thickens the grease on the coils, so a spring that has already used most of its cycle life is more likely to let go on a frosty morning when the door is first opened. The cold is the final straw rather than the cause; the underlying reason is fatigue from years of cycles, sometimes helped along by rust and dry coils.
Oil-tempered springs are the traditional dark grey or black coil; they hold their tension well over time and are widely used. Galvanized springs have a zinc coating that resists rust, which is useful in damp garages, though they tend to relax slightly and may need a small adjustment after settling in. Both are available in standard and high-cycle ratings, and the technician can explain which suits your garage.
