Peter B Fort Meade , FL December 17, 2016 Appliance: General Electric Gas Range JGP628WEC1WW Ge Cooktop Jgp628wec1ww: R/f burner wouldn't light. How to replace Tube Asm Rt Frt. My igniters were old and stuck in the holes. I was told by an appliance salesman on craigslist I had to take off top to replace igniters. Not knowing any better I started removing the top. I snapped off the heads of heads 8 screws and had to drill another 2 out. Took hours.When I got top off I noticed r/f burner center bolt was loose. I tried tightening it. Previous installer did not use anti-seize on aluminum threads and nut was but frozen. Upon tightening it the whole assembly spun and not seeing attached gas line, broke the line. I ordered gas line assembly next day and also saw a video posed by appliance pros how to remove igniters which would have saved hours. I decided to replace burner caps and all igniters to clean things up and avoid future problems. Line an burner fit fine, quick delivery and all is fine now.......pete Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
