A door built around 1992 is old enough that the original torsion spring has almost certainly been replaced at least once, if it hasn't failed outright, but young enough that the opener is usually a chain or belt-drive unit with a circuit board rather than anything from the screw-drive era. The common failure we see on houses from this build window is the logic board going before the motor does, which means the opener seems dead but the problem is electrical, not mechanical. Steel panels from this era also tend to be a single layer without much insulation, so if you've noticed the garage running cold in winter, that's the door, not a draft somewhere else. One honest limit here: if your opener is an exact model from the early 90s, we may not be able to get a matching replacement board. At that point we'll tell you straight that a full opener swap is the cheaper and more reliable path than chasing a part that's not made anymore, rather than quoting you for a repair that won't hold.
