Anyone searching for “PRDS304” has found an older Thermador professional range, 30 inches wide, whose “PRDS” prefix differs from the “PRD…WHU” pattern on current dual-fuel ranges. Its Care & Use Manual lists 36” and 48” siblings (the PRDS36 and PRDS48), so this was one member of a genuine multi-size family and not a one-off.
Wear drives most calls on a range of this vintage. Burner ignition becomes less dependable, oven temperature wanders from the dial, and door gaskets lose their seal after years of heat cycles.
If a burner will not light and you smell gas, close the range’s gas valve before any other step. On a range this old, gas-line and valve parts carry the most accumulated wear, so that rule weighs even more.
The "PRDS" prefix is the clue. Current dual-fuel ranges use "PRD...WHU" or "WDHU" patterns, and this one also predates Home Connect WiFi. A look at the label on the range will confirm the exact model.
It is common on older gas ranges after many heat cycles. We measure the actual oven heat against the setting and look at the parts that control it.
Those siblings (PRDS36 and PRDS48) are in the same family. Call with your model number and we will confirm what we can service. If you can send the model plate details, we can tell you quickly.
