Can You Do This Yourself
A torsion spring holds more stored force than most tools in a garage, and the bars used to wind it are the one place we tell homeowners flatly: don't. We've seen the aftermath of a spring let go mid-wind, and it isn't a bent bracket, it's a trip to the ER. If you're the type who wants to do the diagnosis yourself, that part's fine and even useful before you call: count the coils on the broken spring, note the wire thickness with a caliper, and check whether the door has one spring or two. That saves us a step. But winding, unwinding, or swapping the spring itself needs the right bars, a ladder set up correctly, and hands that have done it enough times to know when something's binding wrong. This is the one place on a garage door job where we won't walk a homeowner through it over the phone.
What You Are Seeing
The door won't budge, or it drops fast when the opener tries to lift it and the motor strains against the full weight instead of a balanced door. Sometimes it's a loud bang from the garage, usually heard from inside the house, which is the spring letting go rather than something failing quietly. On the newer torsion setups standard in Murphy since the mid-2000s, you'll often see the gap in the coil itself if you look at the spring on the shaft, a clean break rather than a stretched or rusted-through extension spring. If the opener still runs but the door only lifts a few inches before the motor gear strips, that's usually the opener trying and failing to do a spring's job, and it's a sign to shut the opener off before it burns out the motor too.
What Can Go Wrong
The most common mistake we get called to fix after the fact is a spring replaced without touching the cables or drums, which then fail within a few months because they were already worn from carrying an unbalanced door. Another is a spring sized wrong for the door's actual weight, which either burns out an opener trying to compensate or leaves the door heavy enough that it slams on the way down. On the newer, heavier insulated doors common in higher-income areas like Murphy, where median household income runs well above the regional norm, homeowners sometimes have doors with added weight from upgraded panels or windows, and that changes the spring calculation from a standard door. If a spring's broken and the door's also showing rust on the track or a bent panel, sometimes the honest call is that spring repair fixes the noise but not the underlying door, and we'll say so rather than sell a spring job that just delays a replacement.
