The PRG486WDG is the all-gas version of Thermador’s 48” Pro Grand® dual-oven range: a two-burner-plus-griddle cooktop feeding two separate gas ovens – a 3 cu ft primary and a 1.3 cu ft secondary on the left – rather than the electric ovens used on the PRD-prefixed dual-fuel models. Because every heat source on this range is gas, from the burners to both ovens’ igniters, isolating which specific burner or which oven is affected is the first step in any service call.
Both ovens run their own Self Clean cycle and Keep Warm mode independently, so a stalled clean cycle or an inconsistent Keep Warm temperature needs to be tied to the specific cavity before further diagnosis. If the griddle, a burner, or either 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.
