The PRG366WG is the highest-output range in Thermador’s 36” gas lineup – six open burners totaling 127,000 BTU over a 5.7 cu ft all-gas oven built to Pro Grand® commercial cabinet depth. Both the cooktop and oven are gas-fired, so an igniter or valve problem can originate on either side, and the oven’s five cooking modes (including Keep Warm) all run through the same gas burner and igniter rather than an electric element.
With six burners on one gas line, a no-light complaint across several burners at once points toward the supply side rather than six separate igniter failures. If there’s any smell of gas or a burner lighting unevenly, shutting off the gas supply to the range comes first, before any other diagnostic step, given the fully gas-fired cooktop and oven on this model.
