Leisure Roma 100 Fan oven has stopped working (Model: RM10CRK)?

Hello all,

A few weeks ago the fan oven on our Leisure Roma 100 stopped working. It had been a little temperamental for a while but has now given up the ghost.

The clock is still working (I say this as i have seen other issues like this and people have asked this) but the oven doesn't do anything (No light or noise)

Do you have any ideas on what it could be? If so, how expensive are the parts and how hard is the repair??

Thanks in advance,

Ricky
