Robert L Vancouver , WA September 17, 2014 Buttons on the old face plate were failing front left had stopped completely I replaced the face plate with the correct part. It was a relatively painless project, the new unit had one fewer screw than the one I was replacing. Everything fit well and it currently functions very well. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
