Thermador cooktop technology
Thermador cooktops span three technologies: gas with patented Star Burners, Freedom Induction with full-surface cooking, and electric radiant. The Freedom Induction cooktop is Thermador’s most advanced — it uses a matrix of induction coils beneath the entire glass surface, allowing any size or shape of cookware to be placed anywhere on the surface. This technology requires specialized diagnostic tools to test individual coil segments, sensor arrays, and the multi-zone inverter control system.
Gas cooktops feature the Star Burner with ExtraLow capability — the five-pointed burner design delivers 56% more flame coverage than round burners and can simmer as low as 100°F. Professional series models include a central wok burner with up to 22,000 BTU output.
What a Thermador cooktop service visit includes
For induction models: each zone is tested for coil output, sensor response, and inverter function. For gas: all burners are tested for ignition, flame quality, and ExtraLow calibration. Gas connections inspected with leak detector. Genuine OEM parts, 30-day warranty.

Frequently asked questions about Thermador cooktops
What is Freedom Induction?
Unlike standard induction cooktops with fixed zones, Freedom Induction has no zone markings. The entire glass surface is active — place any compatible pan anywhere and the sensor matrix automatically detects its position and size, activating only the coils beneath it.
What cookware works with induction?
Only ferromagnetic cookware: cast iron, magnetic stainless steel, and enameled cast iron. Test with a magnet — if it sticks firmly to the pan bottom, it’s compatible. Aluminum, copper, glass, and non-magnetic stainless steel won’t heat.
Is gas or induction more efficient?
Induction is 85-90% efficient (energy to food) vs 40-55% for gas. Water boils about twice as fast on induction. However, gas gives visual flame feedback that some cooks prefer.
Can a cracked cooktop glass be repaired?
No — the entire glass panel must be replaced. It’s one piece. Do not use a cracked cooktop — cracks can allow spills to reach electrical components.
What’s a bridge zone?
A bridge zone connects two adjacent induction zones into one large zone for griddles or roasting pans. Activate it from the touch controls when using oversized cookware.
