We appreciate you taking the time to post a review, tfon117. Let's go ahead and check why your dryer takes time to dry.
Please ensure the dryer is not in ECO DRY mode, as this setting will reduce the power consumption of certain other cycles but will extend the length of the cycle, potentially up to 3 times as long. Eco Dry is on by default on Normal and Time Dry cycles for models with the feature. Please see these links for details.
