On a door this old, the first sign is usually the opener straining on the up-cycle - a motor that used to lift smoothly now hesitates or reverses partway. That's the spring losing tension, not the opener failing, even though the opener is what you notice. A loud bang from the garage, especially on a cold morning, is the spring letting go outright. If the door comes down crooked, hanging lower on one side, check the cable at that bottom bracket before assuming it's the track.
Because Emmett's housing runs older than the newer subdivisions closer to Meridian, these symptoms show up sooner and more often here. A door with original 1977 hardware that's never had a spring replacement is, statistically, living on borrowed time no matter how quiet it's been so far.
