The PRD364WDGU is a 36-inch dual-fuel range in Thermador’s Pro Grand® commercial-depth line – four open gas burners and a built-in non-stick griddle on the cooktop, over a single 5.7 cu ft electric oven cavity that runs True Convection and six other modes. Because it’s dual-fuel, a cooktop problem (a burner or the griddle) is a gas-side repair, while an oven problem (bake, broil, convection) is an electric-side repair, and the two rarely share a root cause.
The commercial-depth cabinet (27 7/8” vs. the standard 24 3/4”) gives this model a larger oven cavity than the standard-depth PRD364WDHU, which is worth noting if parts are being cross-referenced between the two. If a burner or the griddle won’t light and there’s any smell of gas, shutting off the gas supply to the range comes first, before any other diagnostic step, given the open-flame cooktop involved.
