The PRG366WH is the standard-depth counterpart to the PRG366WG: the same six-open-burner concept, but on Thermador’s shallower 24 3/4” Pro Harmony® cabinet with a smaller 4.9 cu ft all-gas oven and slightly lower 120,000 total BTU. Because both cooktop and oven are gas-fired on this model, igniter and valve issues need to be isolated to the specific burner or the oven rather than assumed to share one root cause.
Three continuous grates span the six burners, so an uneven or rocking grate is worth checking for warping before assuming a burner-level problem. If a burner or the oven won’t reliably light and there’s any smell of gas, shutting off the gas supply to the range comes first, before any other troubleshooting step.
