No other 36” gas range in Thermador’s lineup matches the PRG366WG’s 127,000 BTU, which comes from six open burners on a Pro Grand commercial-depth cabinet over a 5.7 cu ft gas oven. Because cooktop and oven both burn gas, an igniter or valve concern may start on either side, and each of the oven’s five modes, Keep Warm among them, is fired by one gas burner and igniter with no electric element involved.
Six burners sharing one gas line give us a quick rule of thumb: several failing to light together suggests the supply, not six separate igniters.
Keep Warm drifting between high and low is another call we see described for this oven. For any gas smell or unevenly lit burner, the range’s gas valve gets closed before we do anything else.
Six full-output burners with no griddle simply add up to more than layouts that give up a burner or two. That is the configuration here, on a commercial-depth Pro Grand body.
Possibly. Because this oven is gas, Keep Warm runs the main burner and igniter at a low cycle rate, so we check the valve and igniter control for uneven cycling, not just the sensor.
The gas parts follow the same checks as on smaller gas ranges. Only the cavity size and the commercial-depth cabinet differ. Parts for this commercial-depth body are confirmed against the exact model number first.
