Be sure your dryer vent is at least 4 inches round. Anything less and your dryer will take forever to dry. Also be sure the dryer setting is set to auto dry not timed dry. Timed dry will dry clothes until that time is up, if dry before it finished the cycle it still keeps drying. A regular load takes about 16 minutes to dry in my dryer. A load of towels or cotton jeans about 25.
