Thermador range engineering and repair expertise
Thermador ranges feature the patented Star Burner — a five-pointed design that delivers 56% more coverage than round burners, with ExtraLow simmer capability reaching as low as 100°F. The Professional and Pro Harmony collections span gas, dual-fuel, and induction configurations in 30″, 36″, 48″, and 60″ widths. The flagship Pro Grand 48″ and 60″ models include integrated griddles, steam-assist ovens, and warming drawers — professional-grade features that require specialized knowledge to service.
Dual-fuel Thermador ranges combine gas Star Burners on the cooktop with an electric convection oven, requiring technician expertise in both gas and high-voltage electrical systems. The Pro Grand’s steam oven adds a water management system with a reservoir, steam generator, and drain — additional components not found in standard ranges.
Common Thermador range issues we repair
Star Burner ignition issues are the most frequent service call. The five-point design has more ignition points than traditional round burners, and each point must seat properly against the burner base for even flame distribution. ExtraLow simmer problems often trace to gas valve calibration — the valve must maintain precise gas flow at extremely low settings, and even minor drift requires professional recalibration.
What a Thermador range service visit includes
The technician tests all burners for ignition, flame quality, and ExtraLow function, verifies oven preheat accuracy with a calibrated thermometer, checks convection fan operation, and inspects all gas connections with a combustible gas leak detector.

Frequently asked questions about Thermador ranges
What makes the Star Burner different?
The patented five-pointed design delivers 56% more flame coverage than round burners. The star shape eliminates cold spots and supports ExtraLow simmer down to 100°F — precise enough to melt chocolate without scorching.
What’s the difference between Professional and Pro Harmony?
Professional has a raised cooktop with bold commercial-style knobs (requires a 10″ backguard). Pro Harmony sits flush with standard 36″ countertops — no backguard modification needed. Same Star Burner technology and oven performance in both.
Gas vs dual fuel — which is better?
Gas: simpler installation, lower cost. Dual fuel: gas burners on top with electric True Convection oven — more precise oven temperature control. If you bake frequently, dual fuel is worth the investment.
How do I clean Star Burner ports?
Use a pin or thin wire weekly — never a toothpick (wood can break inside the port). Remove burner caps, wash with soap and water, dry completely before replacing.
What size range do I need?
30″ for standard kitchens (4 burners). 36″ for the sweet spot (6 burners). 48″ Pro Grand for serious cooking (6 burners + griddle + dual ovens). 60″ for commercial-scale home kitchens.
