no 9inch burnner

the left front burner does not work. the element and infant switch have both been replaced and still does not work. could it be the sminner relay board?

I Have A Kenmore Smooth Top Range. The 9 In Burrner Does Not Work. I Have Replaced The Infanite Switch And The Element And It Still Does Not Come On. I Traced The Switck To A Relay Board
Could This Board Be My Problem?
Please Help, Thanks
