there is NO belt. it is direct drive do not take it apart from the back. the lid switch is probably bad, remove two screws from the lower corner of the console (control panel lower front corners) then pry the brass retaining clips with a long screwdriver by prying to the rear. then pull the cabinet off to you from front. the switch is on the bottom of the top panel neat the lid.
THE MODEL NUMBER YOU INDICATED DOES NOT APPEAR CORRECT, IT IS LOCATED INSIDE THE LID AREA ON THE TOP PANEL.
