Lynn M Granby , MA August 21, 2022 Appliance: Model SGS304CS The original Thermador stove top knobs melted. I have been looking for many years for replacement knobs from my Thermador sgs304cs stove top. The original knobs were no longer in production and the “substitute” knobs were no longer in production. I had given up- even after turning to other manufactures to find a substitute knob. Fiinally, Bosch created these “generic” replacements, and they fit perfectly and look great.
