oven and broiler do not work

Top burners work but when I go to turn on the oven the temperature shows but the cleaning light blinks and nothing will come on same with the broiler when you turn on the broiler the cleaning light comes on. You can not hear any gas coming through at all. I have replaced the Control board and the ignighter in the oven.
