Hi jlucas. This noise is caused when the belt that turns the dryer's drum is slipping. When the drum is overloaded, the belt can't grip the drum as well as it normally would. If you hear this noise, stop the cycle, take some clothes out of the dryer, and then restart the smaller load. On the other side, get in contact with us via 1-Facebook Messenger: http://m.me/samsungsupport 2-Twitter: https://bit.ly/2pTYDc7
