The Whirlpool WP3404233 Dryer Switch Push to Start is a critical component in many Whirlpool, Maytag, Roper, Estate, and Kenmore dryers. This electronic component serves as the link between your dryer's cycle selection and operation. Once you've determined your preferred drying time and temperature, push the Push to Start switch to begin the drying process. The switch completes the circuit by providing a signal to the dryer's motor and control board, which activates the drum and heating element. A malfunctioning Push to Start switch can prohibit your dryer from running at all, even if the other components are in working order. Replacing a broken switch is a straightforward repair that will return your dryer to full operation.
