Hi there I have just bought a second hand cannon camberley double oven.......after using a combi microwave for 3mths with 3 children I was desperate to get a cooker. Just had it fitted and everything works fine on it until it comes to the main oven. There is simply no gas coming out to be able to ignite it.....arrrrggghhh! I was all excited about having a lovely cooker and don't know where to start as i really dont want to get ripped off....again (the lady I bought it off said it was in full working order??...obviously not)......can anyone give me any ideas or advice what to do and where to start.....thanks
