Product review (5 stars): Whirlpool Dryer Repair Kit
A failed motor prompted the repair project and, as long as I had the dryer in pieces, it seemed like a good idea to replace the belt and rollers at the same time.  The Whirlpool 27-inch Dryer Repair Kit arrived on time and in good condition.  I found the installation instructions clear and accurate.  Their hint about installing the belt over the tensioner pulley was particularly helpful.  I'm happy with the product and service.  I'd order from them again.
