Using this Simpson dryer timer knob is a breeze. First, make sure your dryer is unplugged to avoid any electrical hazards. Then, gently remove the old timer knob from the shaft. Take your new timer knob and simply place it onto the shaft, aligning it properly. Press it firmly until it's securely in place. When it comes to maintenance, keep the knob clean by wiping it with a soft, dry cloth every once in a while. Avoid using harsh chemicals or abrasive materials as they can damage the knob. If you notice any problems with the knob, like it becoming loose or not turning smoothly, contact our customer service. We'll be happy to assist you and provide a solution.
