Door continue to drop past limit switch and motor stop

I was not sure at first so I turned the adjuster to be way above the door stop. When I close the door I hear the click of the limit switch or the relay, not sure, but the door continue to drop down like it is not driven anymore. The motor stop but the door not.
As a test, to check the shaft or gear, if I open it and stop it at about 2 feet, it hold there as it should. The opening work perfectly.
