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 first measurements come from the spring that is already on the shaft. The technician measures wire thickness across a run of ten or twenty coils, the inside diameter of the coil, the overall length of the spring when relaxed, and the wind direction, which is read from how the coils lean. On a two-spring door each spring is checked separately, because a left-wound and a right-wound spring sit on either side of the centre bracket. Any tag or colour marking is noted too. These numbers narrow down what the door was built with, and together with the door's weight they point to the correct replacement.
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
A balanced door is also a door you can operate safely by hand when the power is out. Pull the red release cord with the door closed to free the trolley, then lift the door with both hands on the handle or the bottom section; it should rise smoothly and stay open at full height. To re-engage, pull the cord toward the door until the trolley clicks back onto the carriage, or simply run the opener, which reconnects on most models. Because the spring now carries the weight, this is light work, and it is the recommended way to get a vehicle out during an outage.

FeesSame any hour
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.
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.
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.
