The belt

A stretched or broken belt could be the reason why your Whirlpool dryer is not tumbling.

The idler pulley

The main problem with the pulley is that the roller wears out and the belt derails from the pulley preventing the dryer from tumbling. Another problem is that the dryer will start to run very noisy. 

Drum support rollers
