My electric dryer only 2 years old is making a noise like a zipper is tapping the inside of the drum but there is nothing in the dryer, what could this be?

Does it make the noise if you spin the drum by hand? And does it seem to be coming from any particular location in the dryer like down towards the bottom left, under the top, or towards the back?
