Kitchenaide range KGS907SSS00 no bake

[ghserv]

Anyone have any idea which service manual goes to this range? For what it's worth broil works but not bake. Apparently this unit does not use a hot surface ignitor to light the bake, it's a DSI system for the bake burner and HSI for the broil burner. So much for the easy diagnosis.
Any help would be appreciated.
