A door built around 1980 is now about 45 years old, and steel garage doors from that era weren't insulated the way current sectional doors are. The panels are thinner single-layer steel, which means dents show and stay, and the whole door is lighter - so torsion springs sized for that weight are common, and when one goes, the door won't budge, or it'll slam down if the cable's already frayed.
The other thing about houses from 1980 is the opener. If it's original, it's a chain-drive unit with a mechanical limit switch, not the modern optical safety sensors required on anything sold today. That's not automatically a hazard, but it is a part that fails differently than a newer unit - usually the drive gear stripping inside the housing rather than a sensor error code.
Rollers on a 45-year-old door have usually gone through several thousand open-close cycles without ever being swapped. Steel rollers on steel tracks, no nylon, no bearings worth mentioning - so the grinding noise a lot of Jurupa Valley calls start with is just metal wearing on metal, not something exotic. Track alignment issues follow the same pattern: decades of use, no landmark event, just age doing what age does to hardware nobody thought to replace.
