Ender3 Max Neo Y axis failing

When autohoming my printer, when the y axis reached the back it stopped and made a loud vibrating noise,before I switched it off. It has continued to do this each time I try. Can anyone help please.

Check no cables are stopping the activation of the limit switches which tell the printer when its at it end stop place. Its a little rectangle box with a metal blade coming out of it
