Easy to replace with the shield and paddle assembly. Steps are: 1. use a flat head screwdriver to push the tabs at the base of the control panel. remove the wire connectors by gently prying them straight off. 2. remove the 4 phillips screws holding in the old assembly. 3. Install the new assembly by carefully putting the paddle behind the water pipe that sticks out. You may have to push the paddle one way to get it around the pipe and then back into place. 4. reinstall the screws. 5. reconnect the control panel and press it back into place.
