Cannon Cambridge double oven has no gas coming out?

So I had the fuse blow in the plug of the oven and since then I can't seem to get gas to come out the the oven jets, also the oven igniter used to click automatically when the oven knob was turned on. I know all about the clock needing to be in manual and I hear the click when it is in manual but still no gas. I am desperate to fix this as I dont wanna shell out for another oven for what seems such a simple thing, and the rest of the oven works fine (after fuse replacement), i.e. the ring igniter, the oven light and digital clock.
