Thermador Cooktop & Rangetop Repair — Common Issues We Fix
- One Burner Out While the Others Work: When a single burner dies, the fault is usually in that burner's own valve, igniter, or wiring — we isolate and fix it without disturbing the rest of the rangetop.
- Gas Smell Around the Cooktop: Any gas odor with the burners off deserves immediate attention — shut off the supply and give us a call. It's typically a fitting or valve connection that needs service.
- Knobs Stiff, Stuck, or Wobbly: Professional rangetop knobs turn heavy-duty valve stems, and grease migration makes them bind over the years. We service the stems themselves rather than just swapping knobs.
- Touch Controls Acting Up: Spills that seep under the control panel are the usual culprit — sometimes cleanable, sometimes a control board swap.
- Grates Warped or Sitting Unlevel: Uneven grates rock cookware and heat unevenly — we check seating and alignment, and replace them when needed.
- Flames Yellow or Orange Instead of Blue: A sign the air-gas mixture is off or the burner needs cleaning and adjustment — worth fixing for both performance and safety.

Keeping Your Thermador Cooktop in Top Shape
Most cooktop trouble starts at the burner: grease in the ports, moisture under the caps, or grime working its way into the knob valves. A quick wipe-down after heavy cooking prevents the majority of service calls we see.
Thermador Cooktop Maintenance Tips
A few habits go a long way toward keeping your Thermador cooktop performing at its best:
- Dry Burner Caps After Washing: Reseat caps only when fully dry — trapped moisture is a top cause of igniters that spark on their own.
- Keep Grease Away From the Knobs: Wipe the knob area regularly so grease doesn't work into the valve stems and stiffen them.
- Check Grate Seating: Grates that sit crooked rock your cookware and heat unevenly — reseat them after cleaning.
