Oven would not light, broiler would

Remove the cover over the burner, two screws at the rear, this exposes the burner tube cover, one nut at the center. Three screws will remove the holder for the igniter. I had to remove a sheet metal cover underneath the oven( pull the drawer out) to gain access to the plug for the igniter. A good tip on this is the same valve controls the broiler and the oven, if one works and the other doesn't, it's the igniter. If neither works the gas vale may be the problem.
