The Whirlpool WPW10117655 Start Switch allows the dryer to begin its operating cycle when the start control is activated. This electrical component works by sending a signal to the dryer’s control system, initiating operation when the appropriate conditions are met. A properly functioning start switch helps provide convenient and reliable cycle activation during everyday laundry tasks. If the original switch becomes worn or faulty, the dryer may fail to start or respond inconsistently when the start button is pressed. Replacing a damaged switch can help restore normal starting functionality and improve appliance usability. This replacement part is a practical option for dryer repair and maintenance. Proper installation helps ensure the switch operates correctly with compatible dryer components.
