maytag will not spin

Ive Replaced The Lid Switch, Had The Timer Inspected By Tech, I Also Made The Jumper To Test The Motor Which Tesred Ok. The Timer Advances Thru The Complete Cycle. The Water Drains, But The Tub Will Not Spin. When Timer Gets To Spin Cycle Their Is Know Noises, Does The Options Switch Have Anything To Do With Spin Cycle? It Has And Option For Extra Spin, And Another For Fast Or Slow Spin. When On Spin And Knop On Their Is Power To Both Options. In Spin Mode Their Is Nothing???all Other Functions Work Fine. It Will Fill, Wash, Agitate In Wash And Rinse Cycle Just Want Spin.
