What is the Rack Dry cycle used for?

The Rack Dry cycle is designed to carefully dry items that should not be tumbled in the dryer, such as sweaters, stuffed animals, gym shoes, and other delicate items. This cycle uses gentle heat to prevent overheating of items since they are not tumbling. You must insert the drying rack into the dryer drum and ensure no part of the articles hang over the edges.
