The PRG364WDH keeps Thermador’s 36” Pro Harmony format but replaces the electric oven of the PRD-prefixed dual-fuel models with an all-gas one, 4.9 cu ft. Above it come four open burners and a griddle. Since cooktop and oven both burn gas, an igniter or gas-valve concern can appear in either place, and we confirm which one before assuming a single cause.
Despite being all-gas, this range supports Home Connect WiFi. Remote preheat or monitoring that stops working is therefore a connectivity issue, quite separate from whether burners and oven light.
Anything that fails to light reliably, whether a burner, the griddle, or the oven igniter, becomes a safety question when a gas smell is present, and the first move is closing the range’s gas valve.
Gas. Dual-fuel models with a PRD prefix pair a gas cooktop with an electric oven, but this one is all-gas, so bake and broil depend on a gas burner and its igniter.
Typically the igniter fails to get hot enough to release the safety valve, or the valve will not open. Either one needs a technician, so stop retrying the oven.
Yes, this one does, through Home Connect. App trouble is its own issue and does not by itself say anything about the burners or oven.
