KitchenAid started in 1919 as a manufacturer of stand mixers. KitchenAid added refrigerators to their product line in 1986 and used celebrity chefs to help make their brand a household name when it came to refrigerators.
KitchenAid is still known for its stand mixers today. The product has changed very little and the attachments are compatible from the Model "K" produced in the 30's all the way up to the modern refrigerators today.
KitchenAid has a wide variety of side-by-side refrigerator models. Check out AJmadison.com's selection of Kitchenaid side-by-side refrigerators.
