The SGSXP305TS is the 30-inch flagship of Thermador’s gas cooktop line, pairing Pedestal Star Burners (with the QuickClean Base for easier underside cleaning) with 2 ExtraLow simmer burners, for 54,000 total BTU on natural gas and an 18,000 BTU center burner.
Because it combines two distinct burner technologies, troubleshooting benefits from isolating which system is affected: pedestal-burner issues tend to involve spill residue or corrosion under the raised base, while ExtraLow issues are almost always in that burner’s specific knob and valve assembly rather than the gas line itself.

Most Common Issues on This Model
If you smell gas, shut off the gas supply at the shutoff valve first before inspecting a pedestal or ExtraLow burner.
Because pedestal burners aren't sealed flush to the surface, check under the QuickClean Base for spill residue if a burner won't ignite reliably.
An ExtraLow burner that won't hold a low simmer is usually a worn knob/valve on that burner rather than a supply-pressure problem.
