Each burner manifold in the oven has its own
igniter. If the
igniter is defective, the burner assembly will not light. The igniter has to be functioning properly in order for the gas safety valve to open. This is a designed safety feature that prevents free flowing gas from entering the oven cavity without ignition. This reduces the risk of explosions.
There should be a flame spreader metal plate covering the access over the broiler. You will need to access the broiler so you can view the broiler manifold and
igniter. Turn the oven setting to broil and make sure the
igniter begins to glow. If the
igniter fails to glow, replace it. If the
igniter does glow, but you still do not have ignition after 90 seconds, the
igniter may be weak and still require replacement. The following link explains oven
igniter types, their current potential, and how to replace them:
