Nothing broke outright, but the door has grown heavier each winter, opens more slowly and squeals as it moves. The springs on an older door have lost tension and the coils show pitting, so the system is asking for attention before it fails.
The finished result is a door that behaves the way a good garage door should: it lifts by hand with light effort, stays where you leave it at mid-height, closes softly and lets the opener run with little strain. Reaching that point involves measuring the door, choosing a matched spring, winding it to the correct turns and testing the balance through the full travel. The technician then runs the opener's reversal test and lubricates the moving parts. You are left with a record of the spring installed, so future service starts from known specifications.

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 clamped and the opener disconnected, the technician releases any tension left in an intact spring, loosens the drum set screws and slides the drums inward, then removes the old spring from the shaft. Bearings are inspected while the shaft is free. The new spring goes on with its stationary cone bolted to the centre bracket and the winding cone facing the drum. Drums are refitted, cables seated, the shaft levelled and cable tension evened on both sides. Winding follows, then the set screws are seated and the clamps come off for a balance check. Each stage is done deliberately and in order.
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.

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.
Torsion springs mount on a shaft above the door and twist to store energy, lifting the door through cables and drums. Extension springs run alongside the horizontal tracks and stretch as the door closes, pulling it up through pulleys. Torsion systems tend to lift more evenly, take up less space beside the tracks and are the standard on most modern doors. Both are professional service items because of the energy they hold.
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.
