SGS305TS

Thermador SGS305TS

What we most often repair on units like this

  1. With a gas smell, close the shutoff valve first, then look for a cracked burner cap, a blocked port or a reignition switch that has failed
  2. A burner that clicks nonstop or will not catch usually has a dirty or misaligned spark electrode, not a bad gas valve
  3. Flames tipped in yellow or leaning to one side usually trace to a port that is partly plugged, or to a cap resting unevenly on the burner

Think of the SGS305TS as the plain-spoken member of the Masterpiece gas family: five sealed burners across 30 inches, 52,000 BTU on natural gas (45,200 on propane) and a 16,000 BTU burner in the middle for rapid boiling and hard searing. Unlike its siblings, it has no ExtraLow simmer burners, so all five share the same push-to-turn mechanical knob.

Mechanical ignition means the calls we see are rarely electronic. We usually find a spark electrode coated with residue, a cap sitting crooked on its burner, or a relight sensor that no longer notices a flame that has blown out. Any of these can be handled without touching a control board, because there is not one to blame.

Safety order matters here: if gas can be smelled, the shutoff valve comes first, and only then do we examine caps, ports and the reignition switch.

SGS305TSSGS305TS questions
Why does one burner click endlessly?

Constant clicking normally means the spark electrode is dirty, wet or out of line with the burner, so it keeps sparking without finding a flame. Cleaning and realigning it fixes most cases without any part replacement.

What makes a flame turn yellow at the tip?

A port that is partly plugged, or a cap resting unevenly, disturbs the gas and air mix. Cleaning the port and reseating the cap often restores the blue flame.

Does this model have a simmer burner?

No. The SGS305TS has no ExtraLow burners, so all five burners use the same knob. Owners who want very low simmering would look at the SGSX305TS variant instead.
