There is no heat in my Lamona HJA3300 oven. Fan, light and grill all working but no heat when switched to oven

I've just discovered same problem. When oven was switched on last night, a fuse was blown. Everything else reset was fine (grill, fan, light still work, and tv/lights etc), but no heat in oven.
Is there a fuse I need to change? No idea how to deal with the insides of ovens.
