You pulled the red cord to open the door during a power cut and it barely moved. Lifting it took your whole weight, and when you let go it came down hard.
Choosing the right spring is a matter of weight, not colour. Extension springs are rated for the weight they are meant to lift, and the correct pair for your door is found by weighing the door itself with the opener released, then checking that figure against the wire size, coil diameter and length of the old springs. Paint colour on the end coil is only a hint; older springs fade, get overpainted or were never quite right to begin with. A pair matched to the measured weight gives a door that holds at half height and lifts with one hand, and an opener that works lightly.

Scene 1
An extension spring is stretched tight when the door is closed and nearly relaxed when the door is fully open, so the first move is to get the door up. The technician pulls the opener's release, raises the door by hand if it will go, and clamps both vertical tracks below the bottom rollers so the door cannot come down. If a broken spring has left the door stuck partway, it is lifted and supported with the weight taken on clamps and props before anything else is handled. With the door held open, the springs, pulleys and hooks can be examined and removed like ordinary hardware, which is the whole reason the sequence begins this way.
Scene 2
Balance is judged with the opener still disconnected. The technician lowers the door to the floor, then lifts it: it should rise with modest effort, stay put when let go at about waist height, sit steady when fully open, and come down under control rather than dropping. If it sinks, both springs need a little more stretch and each S-hook is moved one hole to take up cable; if it climbs on its own, one hole the other way. Adjustments are always made in pairs, with the door open and clamped again each time, so the two springs stay equal. Two or three rounds usually settle it.
Scene 3
Extension springs are easy to inspect because they hang in plain view. Once a month, with the door fully closed so the springs are stretched, stand inside and look along each one from the back hanger to the pulley. The coils should be evenly spaced along the whole length; a section stretched wider than the rest is a spring losing its temper. Then raise the door and look again: with the door open the coils should close up tight, and both springs should hang at the same height. Rust bloom, a pulley that sits crooked, a cable off its groove or a containment cable hanging loose are all worth a call while they are still small.

FeesSame any hour
Keep a clear zone around them. The springs, pulleys and cables move on every cycle, and anything leaning into their path, such as a ladder, a hockey bag or a shelf edge, can catch a cable or knock a pulley. Storage that crowds the rear hangers also slows any future service. A hand's width of clear air around each spring's full travel, and nothing hung from the springs or their cables, is the rule of thumb.
It is better to leave the door where it is. With one spring gone, the opener is lifting most of the door's weight on its own, which strains the motor, can bend the top section and often throws a cable off its pulley, adding to the work. Use another door in and out, keep the bay clear, and let the technician move the door once it is secured.
They are inspected every time and changed when they show fraying, rust at the bottom loop, or a kink from having jumped a pulley. Cables and springs are generally the same age, and with the door already open and the springs off, fitting new cables adds little to the visit. Bright, tight strands with clean loops can stay and are simply re-routed over the pulleys and set to the new springs.
