Our Whirlpool Duet Washer went out - the dryer worked fine but, we decided to go with a new set. They no longer made the duet system so we were on the hunt for something new.  I thought my older dryer was functioning fine - until I dried my first load in my new GE Profile Dryer!  Wow.  The new sensor for drying has cut my drying times in half!  I kind a wish my washer had given out sooner.  I anticipate saving a lot of energy with this new unit.
