A door built in 1997 is young enough that most of what breaks on it is still a bolt-on part - a broken torsion spring, a slipped cable, a worn roller. None of that is a weekend project if the door is under tension; a torsion spring can put someone in the hospital. What you can safely do yourself: check that the tracks are bolted tight, clear the photo-eye sensors of dust, and listen for grinding in the opener before it fails outright. What you should not do: unwind a spring, adjust the torsion bar, or chase an opener logic board issue by swapping parts at random. At $130,627 median income for this area, most Severn households can absorb a proper repair call rather than a second trip after a DIY attempt goes sideways, and that's usually the cheaper path anyway once you count the second set of parts.
