I have a stoves gas oven which is not working properly. It usually lights first time but will not relight immediately if I have to turn the oven off before opening the door to check the dinner. It will usually relight if I leave it for 10 mins or so. The gas is coming through as I can smell it but there is no spark from the ignition. Is this likely to be an expensive or complex repair, the oven is around 17 years old.
Thank you
