The Samsung DC97-16931B Dryer Control Knob Assembly, a user interface component that allows you to adjust and choose dryer settings. This control knob connects to the dryer’s control panel and works by turning a selector mechanism that communicates the chosen cycle or option to the appliance’s electronic control system. As the knob rotates, it helps the dryer recognize the selected program, such as different drying times or temperature settings. Replacing a worn or broken knob assembly can restore smooth operation and accurate cycle selection, making the dryer easier to use. Designed for compatibility with select dryers, it supports convenient and reliable everyday appliance operation.
