The Whirlpool W11351728 1Dryer Electronic Control Board serves as the dryer's central processing unit. It's a circuit board that takes input from a variety of sensors and components, such as the temperature sensor and timer knob. Based on this information, the control board directs the dryer to take specific actions. For example, if the temperature sensor readings show that the clothes are dry, the control board will instruct the heating element to turn off and begin the cool down cycle. Without a working electronic control board, your dryer would be unable to regulate temperature, cycle times, or even turn on. In essence, the Whirlpool W11351728 1Dryer Electronic Control Board is what allows your dryer to operate intelligently and efficiently.
