If your opener runs but the door stutters partway up or reverses without hitting anything, that's a classic sign in houses from this build period - the drive gear inside the housing has worn down enough that the chain or belt loses tension mid-cycle. It's not a spring problem and it's not the sensors; it's the motor unit itself wearing out after two and a half decades of daily cycles.
Another pattern we see a lot in 1997-era construction: the remote works from inside the car but not from the driveway, or the wall button trips the door but the keypad doesn't. That's usually a receiver antenna or board issue, not a range problem, and it tends to show up right around the same age this housing stock has now reached.
If the opener makes a loud grinding noise and the door barely moves, stop trying it. Repeated attempts on a failing gear can strip it the rest of the way and turn a board or gear repair into a full opener replacement.
