you only hear the timer but no motor correct? you will need to replace this, its the lid switch, its located up in the control panel where the timer is, you can get this @ http://www.repairclinic.com/SSPartDetail.aspx?s=t-LAT4000AAW-%3d%3dei1468&PartID=1468 thanks Bryan
started working after they giggled on the knob, but then the timer started throwing sparks and shocked the guy. I guess the timer needs replaced? the motor and everything attached to it is fine. belts are fine.
