Is your Samsung dryer making a squeaking noise while it runs? One problem could be an issue with the idler pulley. We got a call from a customer in Happy Valley, Oregon about a squeaking issue in a Samsung Dryer. The noise turned out to be a worn idler pulley. When worn or damaged they can cause the dryer to squeak during cycle. The purpose of the idler pulley is to keep the drive belt tight so that it is able to rotate the dryer drum during the drying cycle.
