Hi , problem is definetly the Element as the fan is working , this happened to me 2 years ago on Christmas Eve Morning !. Most Electrical wholesalers sell Elements for the oven , just quote your oven type and they will source the element , mine cost around £15 I believe. Changing the unit is pretty straightforward , you will need to lift out the oven from its casing, its awkward and heavy so ask a mate to assist. The element goes in from the front of the oven , obviously make sure you ensure the supply is completely off !!!! , you disconnect and re-connect from the back of the oven.
