That left side switch needs replacing more often than any other part, imho. You can get a new one from Radio Shack for only about $3. Keep a couple on hand. One tip from my Gammill tech guy: get in the habit of pressing the button only as much as necessary to make it work, and you'll need to replace it less often. Quote: "Quit pressing that button so hard!!" (I had a habit of pressing it all the way down all the time.) Now I slowly press it from the edge.
