After pulling the red release cord, you tried lifting the door yourself and it would barely leave the floor. A door that used to glide up with one hand now takes real effort, which points to the counterbalance rather than the opener.
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
Doors are set up in several ways, and the replacement has to match. The technician notes whether there is one spring or two, whether the shaft is a single piece or two halves joined by a coupler, and what the shaft diameter is. Drum type is read from the drums themselves: standard-lift drums for a normal ceiling, high-lift or vertical-lift drums where the door rises well above the opening, or a rear-mounted assembly in a low-headroom garage. Track radius and headroom are measured because they change how many turns the spring needs and which drums it must work with.
Scene 2
Removing a spring frees the shaft, which is the moment to deal with bearings. The centre bearing, which sits in the bracket between the springs and carries the shaft under constant load, is pressed out and replaced if it grinds or has play. End bearings in the plates at each side are checked the same way. New bearings are seated square, and the shaft is slid back through them and turned by hand to confirm smooth rotation before any spring is wound. Smooth bearings reduce the effort the spring and opener have to overcome, which extends the life of both.
Scene 3
A little care keeps the new spring running smoothly for its full life. Once or twice a year, spray the coils with a garage-door lubricant so the steel moves without rubbing, and do the same for the hinges, roller bearings and the end bearings at each side of the shaft. Autumn is a good time, since cold thickens grease and stiffens hardware. Leave the track dry, because lubricant there collects grit. Over the years, glance at the spring for gaps or rust streaks, and if the door starts to feel heavier by hand, book a balance check before a spring reaches its limit.

Usually a little. A balanced door presents a much lighter load than a door with a broken spring, so the opener's force settings are reset to suit it, and the travel limits are checked so the door seals at the floor and stops cleanly at the top. The technician then runs the reversal test and the photo-eye check to confirm the safety system responds correctly with the new balance.
Not necessarily, and that is fine. The paint colour on the winding cone or coil is a code that identifies wire size and wind direction, and different suppliers use their own schemes, so a matched replacement can carry a different colour than the spring it replaces. What matters is that the wire size, diameter, length and wind direction suit the door's weight and height, which is confirmed by the balance test.
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.
