I have a standard outlet (three prong) in my wash/dryer room. My dryer has a three prong in a different shape. It is bigger and the prongs are arranged in a sort of circular triangle. What is a good solution? Change the outlet to a recepticle that will receive this sort of cord/plug? Change the cord/plug? I went to Home Depot and there were no cords that would work with my standard (3-prong) outlet?
