My enthusiast oven is not getting hot? I have a Neff devotee oven which is built into my kitchen,...

I have a Neff devotee oven which is built into my kitchen, its about eight or nine years dated, I think. The disciple is still working but it is stone cold, no heat at adjectives. I could REALLY do without this of late before Christmas! Can anyone hand over me an idea of roughly how much it might cost to repair, and how effortless it is likely to be to repair? I know I will enjoy to call a professional to be sure, but I want to pick up myself the call out charge if its not promising to be repairable. Any helpful guidance much appreciated.

Take out the shelves, see if you can remove the cover from within front of the fan. (2/3 screw holding it usually).

Then you can usually see the element (a grey ring just about 8-9 inches in diameter). There's usually another screw holding it surrounded by place. Loosen the screws, verbs out the element and disconnect it (push-on connectors). Get a fresh element same size & spec and fit it, reversing the steps.
