High-End Cooktop Repair

A burner that clicks but won't light is usually caused by a clogged burner port, a misaligned burner cap, a worn spark igniter, or a failed spark module. On Wolf cooktops with dual-stacked burners, only one tier may be blocked. On Thermador Star Burners, any one of the five flame points can be clogged independently. If multiple burners won't light simultaneously, the spark module is the more likely cause.

An induction zone that won't activate when you place a pan on it can mean the cookware is not induction-compatible (it must have a ferromagnetic base — cast iron and magnetic stainless steel work; aluminum and copper do not). If compatible cookware still isn't detected, the cause is usually a failed inverter board, a damaged induction coil, or a faulty touch sensor. On Thermador Liberty full-surface cooktops, a single coil failure creates a localized dead zone.

No. If you smell gas near your cooktop, turn off all burners, do not use any electrical switches, open windows, and leave the area. Call your gas utility first to confirm the supply line is safe. Then schedule a repair — the source is typically a loose connection beneath the countertop, a cracked gas valve, or a failed burner seal that we can diagnose and fix on-site.

Yes. The glass-ceramic surface on induction and electric cooktops is a replaceable component. However, it's brand- and model-specific — a Thermador glass top is not interchangeable with a Bosch, even though both brands are made by BSH. Replacement requires lifting the cooktop from the countertop cutout, disassembling the frame, installing the new surface, and reinstalling the unit. We source OEM glass surfaces whenever they are available.

A cooktop is a cooking surface designed to be installed into a countertop cutout — slim, flush, usually with electronic controls. A rangetop is a professional-style cooking surface with the full-depth chassis and heavy-duty grates of a range, but without an oven below. Rangetops look like the top half of a professional range; cooktops look like a built-in surface. We service both — rangetops are covered on our stove and range repair page.

Yes. Modular cooking systems from Wolf, Miele, and Viking use individual modules — two-burner gas units, grill modules, wok rings, fryers, steamers — configured in a custom countertop layout. Each module has its own gas or electrical connection and controls. We diagnose and service individual modules without disturbing the rest of the configuration.

Most cooktop repairs are completed during the first visit when the failed part is something we carry on the truck — igniters, spark modules, gas valves, common control boards. Induction inverter boards and glass-ceramic surface replacements for specific models usually require ordering an OEM part. We tell you the timeline upfront after diagnosis.

Yes. We charge a diagnostic fee for the technician's visit and inspection. When you approve the repair, the diagnostic fee is waived — your service call costs nothing on a completed job. See our current promotions for details on waived diagnostic fees and other active offers.
