You heard a sharp bang from the garage, and now the opener hums for a second and gives up. The door lifts a few centimetres at most, then settles back down as if something very heavy is holding it in place.
On a door with two springs, replacement usually starts with a conversation about scope. Both springs have completed the same number of cycles, so when one breaks the other is typically close behind, and replacing the pair together gives the door two matched springs sharing the load evenly. The technician explains what the installed system is, how each spring is loaded and what the door's weight calls for, then fits and winds the springs as a set. The result is a balanced door with a fresh cycle life on both sides rather than a repair that may be repeated soon.

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
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 technician leaves you with the specification of what was installed: wire size, inside diameter, length, wind direction and the cycle rating chosen, along with notes on any bearings or cables replaced. Keep that record with the door's paperwork or photograph it. It means future service starts from known numbers rather than fresh measurement, and if a door section or opener is ever changed, the installer can confirm the springs still suit the door's weight. Many technicians also mark the installation date on the spring or centre bracket so the age of the system is easy to read later.

The centre bracket anchors the spring's reaction force to the framing above the door, so it has to be solid. If the header has split or softened, or the lag bolts have pulled, the technician can refasten into sound wood, add a reinforcing plate or replace the bracket before the new spring is wound. Dealing with this first keeps the shaft level and the spring pulling straight, which protects the bearings and the door.
A spring that is intact but has relaxed slightly can be given a little more tension, within limits, to restore balance; this is a normal adjustment on a door that has settled. A spring with a broken coil is replaced as a unit, since the wire has reached the end of its life. The technician checks the condition of the steel and recommends whichever restores a balanced, safe door.
It helps to have someone present to open the garage, point out anything you noticed and hear how the door should feel afterwards. The technician needs power at the opener outlet, clear space under the shaft for a ladder, and access to both sides of the door. If a vehicle is inside, it stays until the door is working. Being there also lets you approve any extra items, such as bearings or cables, as they come up.
