Thank you for getting back to me. It is a Neff H7871 GB and is about 5 years old.
Thanks for your message. I have replaced the fuse and opened and closed the door about 100 times and the oven is still working. What should I try next?
There was a spark/flash and the same fuse has blown.
Thanks for the diagnosis. I will have a think about whether I will replace the board or get a new oven - I am doing my kitchen soon so need to factor that in. If I was to replace the board is it just a case of disconnecting the cables removing the 3 or 4 screws, swap the board and replace all the connections, or is there more to it than that?
