What is the Wrinkle Prevent option and how does it work?

The Wrinkle Prevent option adds up to 90 minutes of periodic tumbling after the drying cycle ends to help reduce wrinkling if you are unable to remove the load immediately. You must select it before pressing START/PAUSE to begin the cycle. The Wrinkle Prevent indicator will remain lit and the dryer will continue to tumble even after the Done indicator lights up. (Page 7)
