A torsion spring under tension can take a finger or worse, and that's true no matter how handy you are - we don't recommend touching it yourself, full stop. Smaller fixes are different: tightening loose hardware, lubricating hinges and rollers, clearing track debris, or replacing weatherstripping are all reasonable owner jobs on a door of this age. Where it gets harder is the opener boards - a 25-year-old chain-drive logic board isn't always a straightforward swap, and sourcing the exact replacement can take longer than homeowners expect. If you're not sure whether what you're looking at is a five-minute fix or a job that needs a spring gauge, call before you start.
