motor hummed but wouldn't turn drum

Unplugged dryer and removed screws that hold door in place. removed screws that hold front panel. removed front panel. took drum belt off idler pulley. pulled drum out of dryer cabinet. unhooked wiring harness and removed motor. replaced motor and reversed steps to put back together. Thanks to partselect for getting me the parts so quickly. I ordered the motor on line on Friday and it was at my house on Saturday.
