Jacob B Chicago , IL January 09, 2016 Appliance: General Electric Gas Range JGBC20WEA5WW Ge Range Jgbc20wea5ww: Right front burner was leaking gas. How to replace Gas Range Surface Burner Valve. I ordered a new valve and it came quickly. Took off the old one and opened it up to see if maybe it just needed to be greased to close completely. Had plenty of grease so I trashed it as defective. Installed the new valve in under 5 minutes and it worked great! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
