My LG electric double oven range ([LDE3037ST][1])

[![enter image description here][2]][2]

which is 3 years old made a popping sound accompanied by the smell of burnt electrical parts?/insulation?, and now the 2 right burners don't work. Is it the burner control board? Would a bad relay create a burnt insulation smell? What could the cause be?
