I have a GE Nature Gas stove and the right front burner does not stay burning and at times won't start.
The Model NO. is JGBP85WEB5WW Serial NO. FF259494P

Can someone help me to find out what the problem is, why this burner is not lighting. I noticed that when I removed the parts off the they were black.

What would this cost to get fixed?
