smeg oven and hob ignition failed!

I have a smeg suk92mfx dual fuel cooker. The main fan oven is dead and the ring ignition is not working. Bothe seem to have failed at the same time. The clock/timer is not working or lit up. The small oven is working ok. Is there a fuse that supplies both the main oven and ignition system, and if so where is it? If there is another component that may have failed, where is it located and how do I access it? Any help MUCH appreciated.
