Using this dryer push - to - start switch is simple. Just press the button, and it'll start the dryer momentarily. But remember, since we're not sure which models it fits, you'll need to double - check if it's compatible with your dryer before installing. When installing, be careful with the 6.3mm spade terminals to avoid any damage. Also, as this part is no longer available from the manufacturer, once you install it, try to handle it gently. For maintenance, keep the switch clean and dry. If you notice any issues like it not starting the dryer or loose connections, stop using it right away and consult a professional.
