Whirlpool Duet GEW9250PWO Dryer Timer Counts Dwon but Drum Doesn't Turn

I have a whirlpool duet dryer. Over the past 4 years I have replaced the control panel, the thermal fuse, the heating element, the belt and the electrical control (main). I had the same problem before and one of the above problems fixed it but I cant remember which solution.

When the dryer is turned on, it will light up, sense, the timer will count down, but the drum is not turning. I can hear a click from the control panel located on the top left, but nothing happens. The timer will count down through the entire cycle as if the dryer is working. Any suggestions will be helpful.

You may want to start the troubleshooting by removing the toe panel and checking if the belt is not broken.
