The SGSX305TS is the ExtraLow version of the SGS305TS, adding 2 dedicated ExtraLow simmer burners alongside the standard 16,000 BTU center burner, for a total of 52,000 BTU on natural gas. ExtraLow burners use a push-in-to-turn knob distinct from the standard burner knobs, letting them hold very low, steady simmer temperatures.
Because the ExtraLow function lives in the burner’s control knob and valve assembly, a burner that won’t simmer low enough – or won’t stay lit at the lowest setting – almost always traces back to that specific knob/valve rather than the gas supply or regulator, especially if the other 3 standard burners work normally.

Most Common Issues on This Model
If you smell gas, shut off the gas supply at the shutoff valve first before troubleshooting an ExtraLow burner.
An ExtraLow burner that won't hold its low simmer setting is usually a knob or valve-stem wear issue on that specific control, not a whole-cooktop problem.
All igniters spark together whenever any single burner is turned - if every igniter is clicking at once with no gas smell, that's normal behavior, not an error.
