If the door's original to a house built close to 1970, the symptoms tend to run in order: first a louder-than-usual cycle, then a door that hesitates partway up, then one that won't move at all. That's the spring losing tension gradually rather than snapping outright, though in the cold here it can go either way - the severe climate band makes sudden breaks more common in January than in July.
A cable that's frayed but not yet snapped will usually show as a door that runs crooked, dropping faster on one side. That's not a job to keep running on - a cable under tension that finally gives can bend a track or damage a panel on the way down. Given the income level and housing age typical in Northville, we more often get called in before full failure than after it, which is the cheaper way for anyone to have this conversation.
