Are clothing items removed prior to cycle completion?
If clothes are removed from the drum prior to completion, the clothes do not go through the cool down mode of the cycle.
When the clothes are pulled out hot from the dryer and placed in a basket to be put away, wrinkles can set in.
The cooling portion occurs during the last five minutes of the cycle.
This mode continues to fluff items while they cool, which helps prevent and reduce wrinkling.
