The Whirlpool W11501455 is regulating center at your reach for your Whirlpool washer/dryer combo. This ostensibly simple knob serves as the link between your selected wash or dry cycle and the machine's internal workings. Consider W11501455 to be the conductor of an orchestra. As you turn the knob to pick settings like "heavy duty wash," "delicates," or "timed dry," a mechanism inside the knob turns your selection into electrical impulses. These impulses are subsequently transmitted to the electronic control board, which serves as the brain of the washer/dryer.The control board interprets these signals and takes on the role of director, commanding various components to complete the desired cycle.
