A loud bang, and now it won't lift
Or it feels far heavier than it should, and the opener strains and gives up.
A single loud bang from the garage, then a door that won't lift, or lifts a few centimetres and stops. By hand it feels like dead weight.
That is the classic signature of a snapped torsion spring. The coil above the door carries most of its weight, and when it lets go, the full load comes back at once. Springs wear by cycles rather than years, and on Cameron Park's early-2000s first-wave homes plenty of original springs are reaching the end of their run together.
Don't force the door up by hand and don't keep running the opener. An unbalanced door can fall. Leave it where it sits, keep kids and cars clear, and never unwind or back off a spring yourself: the stored tension is the dangerous part.
Book a repair and tell us it reads like a spring. The crew arrives knowing what the job probably is, with the gear laid out before the first bolt moves.
A read-out is a likely cause, not a diagnosis. The tech confirms on site before any work starts.
