SGSX305TS

Thermador SGSX305TS

What we most often repair on units like this

  1. With a gas smell, close the shutoff valve before you troubleshoot an ExtraLow burner
  2. A simmer burner that cannot stay low typically points to a worn knob or valve stem on that one control, not the whole cooktop
  3. When every igniter sparks together as one burner is turned on and there is no gas smell, that is normal behavior, not an error

Add two ExtraLow simmer burners to the SGS305TS and you have the SGSX305TS. The 16,000 BTU center burner and 52,000 BTU natural-gas total stay the same, but the two simmer burners are run from knobs that are shaped differently from the standard ones and are designed to sit at a very low, steady flame.

That feature lives in the knob and valve assembly, which tells us where to look. If a simmer burner won’t go low enough or goes out at its lowest setting, and the other three burners behave, the trouble almost always sits in that specific control instead of the gas supply or the regulator.

One thing often mistaken for a problem: all igniters click together whenever any burner is turned on. With no gas smell, that chorus is how the cooktop is meant to work.

SGSX305TSSGSX305TS questions
Every igniter is sparking at once. Is that wrong?

On this cooktop the igniters spark together by design, so any burner call triggers them all. With no gas odor it is normal, and only continuing clicks after the flame is steady need attention.

One simmer burner won't stay lit on low but the others are fine. What does that suggest?

It points to that burner's knob or valve stem, since the other burners prove the gas supply is good. We check for wear and residue in that control before anything else.

How are the ExtraLow knobs different?

They are push-and-turn knobs, distinct from the standard ones, and they allow very low, steady simmering. Because of the extra mechanism, they are the first suspect when a simmer setting stops holding.
