SGSX365FS

What we most often repair on units like this

1. Knob light ring that stays dark
2. Burner that takes several tries to ignite
3. 18,000 BTU center flame that burns yellow
4. ExtraLow setting that dies at its lowest level
5. Reignition clicking after the flame is lit

The glowing ring around each knob on the SGSX365FS is easy to like, and it is also one of the things we get asked about most when a ring goes dark. The ring is a lighting circuit separate from the gas, so a dark knob does not mean the burner is unsafe, but it is a clue about the wiring behind the control panel.

Our visit starts with the 18,000 BTU center burner, since it carries the most gas, and we check flame color and height. A yellow flame often means a partly blocked port or an air-mixture problem. Then we go through the other four burners and the ExtraLow simmer, and confirm the 15 A, 120 V supply is steady.

For this 36-inch model, Thermador lists SGSX365TS as the successor.
