The PRG364WDH is an all-gas version of Thermador’s 36” Pro Harmony® range – four open burners and a griddle on the cooktop, feeding into a single 4.9 cu ft all-gas oven rather than the electric oven used on the dual-fuel PRD-prefixed models. Because both the cooktop and the oven run on gas, an igniter or gas-valve problem can show up in either location, so it’s worth confirming which one is actually affected before assuming a shared cause.
This model is Home Connect® WiFi-enabled despite being an all-gas range, so remote preheat or monitoring problems are a connectivity issue separate from whether the burners or oven itself are working. If a burner, griddle, or the oven igniter 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.
