Washer tub was not spinning

Smelled burning rubber, checked belt. Belt was cracked and worn out. Easy repair. Removed front of the machine held together with two screws at the bottom of the unit. Removed top cover of machine (the part with the lid). It just pops off. Pushed tensioner wheel in and took off old belt. Putting new belt on was super easy. Working like a champ now. $20 total with shipping. Not too bad to save a washing machine.
