I looked up the parts on your site ordered them and received them in 2 days. I removed the screws on the inside of the door which released the exterior panel. I removed the top faceplate to expose the button controls. The new On/off button snapped into place easily. The new end cap fit on the end of the handle and screwed it in from the backside of the exterior panel. I put the panel back and replaced the screws. Then I put the faceplate back over the controls, replaced 3 screws and I was done. It probably took 20 minutes beginning to end.
