Using this stove control knob is easy. Just align the flat side of the shaft with the corresponding part on your stove and push the knob on firmly. When turning the knob, do it gently to control the heat settings of your stove. Before using the new knob, make sure your stove is turned off and unplugged to avoid any electrical hazards. If you notice that the knob becomes loose over time, you can try tightening it gently. To keep it looking good, clean it regularly with a soft, damp cloth. Avoid using harsh chemicals as they may damage the white finish. If you have any questions or concerns during use, don't hesitate to contact us.
