I have a NEFF J1ACE2HN0B built under double oven. The element has failed after on 26 months (2 year guarantee!) and I am looking to replace it myself. I have the correct replacement part but looking at the oven/element it appears that one of the fixings is bolted through the rear of the oven, rather than just being screwed into place. As a result, it seems that the entire oven will have to be removed and the back opened up to undertake the repair. Has anyone else had this issue? It seems rediculaous that what should eb a 10 minute job requires the oven to be removed and the back opened up!
