KitchenAid KGSA906PSS00. Stovetop range is subpar but that is not why I'm here. When preheating/baking something, the entire time the oven is on, every 60 seconds I hear a click-click-whoosh-phoosh, silence. 60 seconds later, same thing. It goes on like this the whole time I am baking. The oven is hot and the food cooks normally I guess. My concern is whether or not this is normal and/or safe. I've had other gas ovens and they never cycled through anything like this.
