my baumatic oven blew up!!! Help!!!?

I have a Baumatic oven - 9BT2760SS 90cm Multi-function twin cavity cooking theatre - which is approx 4 years old... We've replaced element once and all ok. However the other day put fan oven on to pre heat and after approx 5 mins there was a loud pop/bang, some smoke and the element at the back was glowing bright orange and the digital timer stopped working. The other convential oven still works and we have subsequently replaced the element again (assuming this was the problem). However the fan oven still does not work and LCD dispay still not working. Is there an internal fuse for each oven seperatley which may have blown? Any help much appreciated.
