Using your Westinghouse control knob is easy. Just turn it gently to adjust the heat settings on your cooktop or stove. Make sure you align the flat side of the shaft correctly according to the position of the pointer. Before installation, check the model number of your appliance to ensure a proper fit. If you're not sure, contact us. When cleaning, use a soft, damp cloth to wipe the knob. Avoid using abrasive cleaners as they can damage the finish. Store the knob in a dry place when not in use. If you encounter any issues during use, feel free to reach out to us for assistance.
