Wolf built the GR488 as a 48-inch range with eight open burners, and unlike the Dual Fuel line it keeps gas on both sides of the appliance — the oven cavity is heated by a gas burner and regulated by an oven thermostat rather than by an electric element and a solid-state sensor.
Ignition faults across the GR488’s burners are diagnosed one burner at a time, because the spark module fires all of them together — so a module problem shows up everywhere at once, while a single stubborn burner is local to that burner.
Knowing how these numbers are built saves time when parts are ordered: GR for Gas Range, 48 for the cabinet width in inches and 8 for the eight open burners.
