Fitting five burners into 30 inches is the whole idea of the SGSX305FS, and it is why the center position carries 16,000 BTU. Owners usually cook with a big pot in the middle and smaller pans around it, which puts spills into the sealed burner bowls in the front half. A clogged port or a wet electrode is the most frequent reason a burner refuses to light.
On arrival we test each of the five burners separately, then watch the ExtraLow simmer function over several minutes. Stainless steel surfaces show heat discoloration, but that is cosmetic. The 120 V supply at 15 A powers reignition, and a loose plug or tripped GFCI outlet will stop all sparking at once.
SGSX305TS is the successor model named by Thermador. We check the rating plate before ordering and give you the written price first.
It needs a hood sized for the cooktop. We do not alter venting, but we mention it if smoke or grease is a concern.
Turn it off and let us look. A dirty port or a weak igniter is the usual cause.
The continuous grates sit on rubber feet that wear. We replace the feet when they have hardened.
