The OP has suggested that the oven works OK in the fan mode

No the only mode that works is with just the internal lamp selected, if
any elements are selected but the stat isn't turned right down it trips
(immediately or within a few seconds depending if it's hot/cold)

When you think about it, once you pass any current through any
element, you are going to lift the neutral potential just a little
bit. If you then have a short to earth on any element anywhere you may
get a trip.


But the OP has said it fails when no element is (or should be) switched
on i.e. internal light only on then temp control turned to just above
zero. I also have 10 year old Neff oven)

A netral erath short will trip an RCD whn no equipment is on. It is most
annoying as it will manifest when something unreleted is switched on and
neutral current is 'passing by' your appliance
