My husband and myself didn't agree on which part was the exact problem. He felt it was the valve. I felt it was the ignitor/ orifice. And we both agreed the Harness-Ignitor needed to be replaced. So we ordered all 3, and I'm not sure if in fact all three were needed or not, but now with those parts replaced, the range is working like brand new!! Thanks to all the videos and diagrams on the website we were able to fix it ourselves easily. And the price was cheaper then other websites, also it shipped super fast!
