Snapped and Slipped Lift Cables in Crown Point
The first sign is normally something you can see. One side of the door sits higher than the other, the gap along the top runs wide at one end, and the whole thing wedges in the opening on the way down. That is a lift cable which has broken, come off its drum, or unwound out of step with its partner.

Cables are the link between the spring shaft and the bottom of the door. A steel wire runs from a bracket at each bottom corner, up the side of the opening, and winds onto a grooved drum at the end of the shaft. Both sides have to wind and unwind together. The moment one stops matching the other, the door goes out of square.
Where the wire actually gives out
Nearly always at the bottom, in the last few inches above the bracket. That is the length sitting in whatever is on the garage floor: meltwater, road salt carried in off Northwest Indiana winter roads, grit tracked up from the alley. It stays damp the longest and corrodes from inside the strand outwards, so a cable can look perfectly acceptable from a step ladder and still be down to a handful of good wires.
The other common failure has nothing to do with the wire at all. If the door catches on something on the way down, the drum keeps turning while the door stands still, the cable goes slack and jumps out of its grooves. Nothing has broken at that point, but pressing the opener again afterwards will do real damage.
The bracket at the bottom corner is off limits
The fitting the cable anchors to at each bottom corner carries the full tension of the counterbalance whenever the door is down. Undoing its bolts with the door closed releases all of that in one movement. It is the most common way people injure themselves on their own garage door, and there is no technique that makes it safe until the tension has been taken off the shaft first.
It is also why a broken cable is not something to work around for a week. With one side gone, the door is holding itself on a single wire and a fixing that was never designed to carry the load alone.
Replaced in pairs, then set true
Both cables come off together. They share an identical service history, and running a new wire against an aged one loads the door unevenly from the first cycle. Replacements are sized to the door height and the drum, and the drums are re-indexed on the shaft so both sides pick up at exactly the same point.
Then the door is proved: run to full travel, checked level against the header, and tested by hand at mid-height with the opener disconnected. While the tension is off we look over the bottom brackets, the drums and the shaft bearings, because a cable that failed early almost always had help from one of them.

Questions
Crown Point questions about this job
One cable snapped and the door is hanging at an angle. Can I still use it?
No. Leave it where it is, unplug the opener and keep the cars clear. Every cycle on a single cable drags the door harder into the track and turns a cable job into a track and panel job.
Why would a cable rust at the bottom when the rest of it looks fine?
Because the bottom foot spends winter sitting in salty meltwater off the driveway. The damage begins inside the strand where nothing shows, which is why a look from the ground is not much of a test.
Is a loose cable the same problem as a broken one?
Different fault, same urgency. A slack cable has usually jumped the drum after the door caught on something. The wire itself may be sound, but until the drum is re-seated and the tension evened, the door keeps pulling out of square.
