Laid out with six open burners across a 36-inch top, the R366 is an all-gas range. Its cooktop ignition runs through a spark module feeding an electrode at each burner, and each burner valve carries its own micro-switch that tells the module when to spark.
When a burner on the R366 clicks without lighting, the usual short list is a dirty or cracked electrode, a burner base sitting slightly out of position, a failed micro-switch at that burner’s valve, or a spark module on its way out. Wolf’s own service documentation for this generation walks through exactly that sequence.
There is no mystery in the model number: R for the original professional gas range line, 36 for the cabinet width in inches and 6 for the six open burners. That convention has barely changed since: Wolf still spells the same charbroiler, griddle and French top options the same way on its current ranges and rangetops.
