Remove the full oven from your kitchen unit and turn it on its front, be careful not to damage door etc. Undo all the 8 screws onthe rear and remove panel. Check all connections, there are 2 fans on this model. It could be the fan thats clogged with grease or just faulty. Its easy to replace, unlike the heating element unfortunately. MAKE SURE ITS UNPLUGGED!!!
