The same has happened 2 mine. The slector switch (For Grill/Oven) Has a metal bar with a spring attathed. this basically stops you from having BOTH Grill & oven gas valves open. Adjustment of this spring should allow you to select properly. I havent found out EXACTLY how this needs to adjusted yet but Ill post again when i know for sure.
Do NOT attempt any work on your cooker if youre not competant!! you should be corgi registerd and you risk causing a gas leak!!
