Blocked or misaligned photo eyes
A bin, a bike or a coiled hose sitting in the beam. Or a bracket knocked loose so the eyes no longer line up.
Fix: Clear the path, wipe both lenses, and line them up until both LEDs are steady instead of blinking.
Usually it's the safety sensors. The two photo eyes near the floor have to see each other, and if something is sitting in the beam or one has been knocked out of line, the opener refuses to close the door and blinks at you to say so. Clear the beam, wipe both lenses, then look for a steady light on each sensor.

Cobwebs and dust are enough to do it. Common on a garage that stays shut for weeks.
Fix: A dry cloth on both lenses.
Staples driven through the wire, or a terminal that's worked loose at the opener head.
Fix: Needs checking at both ends. Call if the LEDs stay dark.
The opener thinks the floor is lower than it is, hits the ground early and reverses.
Fix: A travel limit adjustment on the opener. Quick to correct, easy to get wrong.
The door is out of balance, binds in the track, and the opener feels the resistance.
Fix: Stop using it and call. This one isn't a setting.
