Ponch G Bryan , TX November 16, 2015 The knobs to turn on the burners were showing wear and were no longer able to turn the burner on I looked online and found a match for the current knobs. I ordered them and within 48 hrs. I changed all 4 of them and was cooking again. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
