If a cable snapped, don’t open the door. The one good cable pulls all the weight to a single side, which twists the tracks, pops the rollers, and can drop the door. Disconnect the opener, keep everyone clear, and call (323) 282-5672.
If you spot brown dust or metal shavings near the top corners, that’s the cable grinding on the drum and about to fail. Have it checked before it snaps. And never unscrew the red-tagged bottom bracket, because the spring holds deadly tension on it.
