Douglas B Skull Valley , AZ January 27, 2017 Appliance: General Electric Gas Range JGBP28DEM7WW Ge Range Jgbp28dem7ww: Left front burner igniter not working. How to replace Range Spark Ignition Wire Harness. I changed wiring harness due to frayed insulation, replaced igniter (just because it wasn't very expensive) and replaced the faulty rotary switch. Put the stove back together and it works fine. I will be returning the spark module because it wasn't needed. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
