Joyce B Groveport , OH August 02, 2016 The burner knobs head gone bad I called Appliancepartspros and they had the knobs I needed for my range. I receive them in 3 days. My husband put them on the day we got them and they worked great. I was so pleased with the guick service and the helpful lady ( Kathy I believe) that helped me on the phone. Thanks Appliancepartspro! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
