The PRD366WHU is the standard-depth, six-burner version of Thermador’s 36” dual-fuel Pro Harmony® range: the same 99,000 BTU, six-open-burner cooktop concept as the commercial-depth PRD366WGU, but built to the shallower 24 3/4” cabinet depth with a correspondingly smaller 4.9 cu ft oven. As with the rest of the dual-fuel lineup, cooktop and oven problems are independent gas and electric systems.
Three continuous grates span the six burners on this model, so a grate that rocks or sits unevenly is worth checking for warping or a bent support bracket before assuming a burner problem. If a burner won’t light and there’s a gas smell, shutting off the gas supply to the range is the first step, ahead of any other diagnostic action.
