Hello, I'm hoping for some help. I've replaced the Igniter in the lower oven of my GE Cafe Series (Model CGS990SET4SS) 2 different times. When I preheat the oven the igniter bar comes on but the entire chamber fills with gas and then WOOSH! it lights sending a flame 2-3 feet out the bottom of the oven. I'm pretty sure that "trauma" is what's blowing the igniters but I don't know what else to replace. It's almost like the igniter isn't getting hot enough to light the gas until there's a bunch of gas in the space. This is unsafe and I'd like to repair it property. Thanks for any help you can be!
