Ms D Natick , MA May 06, 2016 Broken stove burner control knobs for my old thermador I searched and searched for knobs to replace a couple that were broken on my Thermador dual fuel slide in stove - it is 15 years old and still works well but the knobs started breaking. Thermador/Bosch do not make the replacement knobs. I read a review of these knobs from someone who sounded like they had similar problem. The knobs are smaller than my original but they fit and they work great! Phew! Glad I got that solved. 10 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
