Craftsman 1/2 hp garage opener- buzzing- DESPERATE
You should only press the buttom momentarily. Don't hold it pressed.
If you have to continue to hold the button, then there is a malfunction.
The button isn't what opens and closes the door. It simply sends a signal to the actual opener to do its thing.
It's like pressing a doorbell button. Holding down the button after the initial "press" doesn't make it work better.

Your problem sounds like the motor is not turning. If that's the case, it's either the motor, the gears, or a mechanical problem with the door itself.
First, can you open the door manually when the opener is disconnected? Does it open and close smoothly? (It's not manually locked is it?)
Second, with the gears disconnected from the motor, can you move them?
Third, with the motor disconnected electrically and mechanically, can you turn its shaft?
One of these 3 tests should help point you to the problem.
