I’m having a bit of trouble locating a r/h oven base element for this dual-fuel range cooker. Managed to find a manual on-line with the spare parts diagrams. The part number is AG4M250508 for pre M06-193 and AG4M251282 post M06-193, which I presume is a date code, don’t know which yet. Does anybody know a supplier for AGA bits or an equivalent?
