Common solutions for: Dryer drum not turning

01 - Drive Belt (top solution)

The drive belt is a very long, slender belt that wraps all the way around the dryer drum, around a tension pulley, and then around the drive motor pulley. Over time, the belt can break from normal use. If the belt is broken, the dryer won’t turn. To quickly determine if the belt is broken, reach into the dryer and turn the drum by hand. If the drum spins very easily, the belt is likely broken. Next, inspect the belt to confirm that it is broken. If the belt is broken, replace it.

02 - Blower Wheel (highly likely)

The dryer blower wheel is the component that circulates the air through the dryer drum. Since the drive motor that rotates the blower wheel will often drive the belt that turns the drum as well, an obstructed blower wheel could prevent the drum from turning. Inspect the blower wheel and housing for any obstruction and replace the component if necessary.

I'm on it! Thank you very much, I'll let you know.

Your dryer has a broken-belt safety switch. The controls may activate but the motor (and heat) won't run if the belt is broken. It was manufactured by Samsung for Maytag during the time that Maytag owned the Amana brand, possibly continuing for a while after Whirlpool bought Maytag in 2006.
