Short answer: Not every garage door problem needs a service call, but a few can send you to the emergency room. Here is an honest breakdown of what a handy homeowner can tackle on a Saturday and what should always go to a trained technician.

Jobs most handy homeowners can safely handle
Plenty of routine garage door care is genuinely DIY-friendly. Lubricating the rollers, hinges, and springs with a garage-door-specific silicone or lithium spray a couple of times a year keeps things quiet and extends part life. Tightening loose lag bolts and hinge screws, wiping down and realigning the two photo-eye safety sensors near the floor when the door won't close, replacing worn weatherstripping along the bottom, and reprogramming a remote or keypad are all low-risk tasks that require nothing more than basic hand tools and patience. The common thread is that none of these jobs put you in the path of a component under high tension. If you can do it with the door fully open and supported, or fully closed and at rest, it is usually fair game.
Repairs that belong with a professional
Anything involving the springs, cables, or the door coming off its tracks should go straight to a technician. Torsion and extension springs store tremendous energy, and the lift cables are wound under that same load — a slip can break bones or worse. Replacing a spring, restringing a cable, straightening a bent track, or rehanging a panel that has jumped the rollers all demand specialized winding bars, clamps, and experience most homeowners simply do not have. The same goes for a door that suddenly feels twice as heavy, sags on one side, or crashes shut faster than it should; those are tension-system symptoms, not opener problems. In these cases the safe move is to stop using the door and call for service before something fails the rest of the way.
A simple test when you are not sure
When a repair falls into a gray area, run the balance test. With the door closed, pull the opener's emergency release cord to disconnect the motor, then lift the door by hand to about waist height and let go. A healthy, properly balanced door should stay roughly in place. If it slams down or flies up, the spring system is out of adjustment and the fix is not a DIY one — re-engage the opener and call a pro. As a rule of thumb, if a job requires you to put your hands near a spring, cable, or the top drums, or if you would have to hold significant weight to do it, that is your signal to hand it off. There is no shame in a service call that keeps all ten fingers attached.
