When using the fan function on the main oven the rcd trips out after about 15 minutes. I've changed the central fan element-still have the fault. Oven works fine in all other modes. Is it the fan motor? Cooling fan operates ok on all modes

My guess would be the roof element - internally shorting to its outer case and caused by a slightly higher temperature when the fan blows air about. An RCD trip is much more likely to be element related than fan.

But I know nothing and only guess... It might be the fan...

Which is easier to change?

Good Luck..., September 2016

Sounds like it.
