The SGSP305TS swaps Thermador’s flush sealed-burner design for Pedestal Star Burners, which sit up on a raised base with a QuickClean Base underneath for easier wipe-down. It still totals 54,000 BTU on natural gas across 5 burners, with an 18,000 BTU center burner for high-heat searing.
Because pedestal burners aren’t sealed to the cooktop surface the way standard SGS burners are, spills can seep underneath the burner base rather than staying on top – so when a pedestal-style burner acts up, checking the base and igniter for moisture or residue is worth doing before assuming a valve or regulator problem.

Most Common Issues on This Model
If you smell gas, shut off the gas supply at the shutoff valve first before inspecting the pedestal burner assembly.
Because the burners sit on a pedestal rather than being sealed flush to the cooktop, spilled liquid can run underneath - check the QuickClean Base and igniter for corrosion if a burner is intermittent.
A center burner that runs weak is often a clogged pedestal burner port rather than a regulator problem.
