Use a hair dryer and a flat paint scraper to remove the old one. It comes off fairly easy. You can remove it without a hair dryer it's just a lot easier. Do this: Unplug or remove power from the machine. Before you remove the one on there now, disconnect the keytail connectors and connect the new keypad keytail connectors. Restore power and check if everything works. If everything is working remove the old one and install the new one. If there's still a problem and you need to replace the control, wait until you get it and then install the keypad. That way you won't need to remove the keypad twice.
