LG dryer will not start just buzzes - LG DLG2525S Electric Dryer

Try this:
Unplug the dryer, reach inside the drum and try to rotate the drum 1/4-1/2 turn. Plug the dryer back in a push the start button. Sometimes motors get dead zones in them, and this will move it from that zone.
If that doesn't work, then you will have to go farther.
If you have a front loading machine, remove the front, this will expose the belt and drum, check the belt to see if it is broken, if not then remove the drum and belt and this will expose the motor, idler arm with pulley, Your belt may have slipped off the motor pulley or the idler arm pulley.
Before reassembly, lubricate the drum rollers at the shaft with a good grade of machine oil such as 3 in One Oil.
I hope this helps
