A door built around 1970 was engineered for the weight and insulation standards of that era, which is lighter than most doors sold today. If a previous owner replaced the door with a modern insulated model but kept the original springs, the springs are working harder than they were sized for - that shows up as a door that feels heavy to lift by hand or an opener that strains and eventually burns out early. We see this pattern often enough here that it's one of the first things we check on an older Bensenville door.
Winters in this area run cold, and steel contracts in low temperatures. On a door with worn rollers or a track that's already slightly out of alignment, that contraction is often enough to turn a minor rattle into a door that jumps the track. None of this means your door is a lost cause - most of these issues are a spring, a set of rollers, or a track adjustment, not a full replacement.
