I thought it was the oven burner igniter causing the problem, but called a repairman to be sure. He said the igniter was good; it was the control board that needed to be replaced. Ordered a new control board and overlay (it comes in two parts) and a new oven sensor as the repairman suggested. Parts came when they said they would and I was able to install them myself. Works like a charm. Thank you AppliancePartsPros.com
