Karen A El Dorado Hills , CA March 10, 2015 The largest burner was getting gas to it and clicking but would not ignite and i had already replaced the ignition piece Bought the spark switch assembly. It looked quite different from what was originally installed and went on in a different configuration, which was confusing - but just by following the instruction diagram that came with it (very closely), everything works great. 10 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
