Door hangs lower on one side
A cable has slipped off its drum or snapped.
Safety critical
Lift cables carry the door's weight alongside the springs. A frayed or snapped cable leaves the door crooked, unbalanced and genuinely unsafe to operate.
What is involved
A cable rarely fails on its own. Something caused it — a misaligned drum, a worn bottom bracket, or a door that has been running out of balance.
Warning signs
If any of these sound like your door, it is worth a look before it turns into a callout at midnight.

Straight answers

Yes. The door is unbalanced and can drop. Stop using it, leave it where it is and call.
They wear together, and matched lengths are what keep the door square. Replacing one leaves you with mismatched tension.
The bottom bracket is under full spring tension. It should only ever be removed by someone who has released that tension first.
