not enough info... different over have different types of ignitions... from what you say, I assume you have a spark ignitor which lites the burner. It no longer makes a clicking noise to light. A kenmore with the model # beginning with a 665.xxxxxx which is made by whirlpool.. if so could be the range control or the direct spark ignition board.. if oven doesnt have the spark ignition i would need more info as to type of ignitor and or model #....
