Henry B Airway Heights , WA September 11, 2016 Appliance: Model FRIGIDAIRE F11 error code After reading others' experiences, I decided to order the faceplate only. It was very easy to remove the control unit but the faceplate itself had to be carefully removed. I replaced the faceplate and my oven now works. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
