Product review (5 stars): The self cleaning mechanism had a recall and all the new units do not have the problem
After reading the reviews on the problem on self cleaning, I called Whirlpool at 800-4221230. All new units have had the problem fixed and there was a recall on the older units. Call for yourself if you don't believe me.

This is the perfect small oven that fits cookie sheets and large roasting pans. Most 24" ovens do not have as large of an interior capacity. Well worth the price tag!
