A visible gap in a torsion spring
Torsion springs are commonly mounted on a shaft above the door. When one breaks, a separation may be visible in the spring coil.
The door becomes very heavy
Springs provide counterbalance. Without that assistance, the door can feel far heavier and the opener may lift only a short distance or stop.
You heard a loud snap
A spring can release with a sharp sound. If that is followed by a heavy or non-opening door, avoid further operation and arrange service.
