Why does my gas cooktop keep clicking after the burner lights?

Constant clicking usually means a valve switch is stuck or wet, often after a spill or cleaning. It can also point to a failing spark module or a misplaced burner cap. If drying the area doesn't stop it, the switch or module may need to be replaced.

Can you repair induction cooktops?

Yes. We diagnose induction cooktops by reading error codes and testing the power and generator boards, coils, sensors, and cooling fan, then replace the failed part.

Do you need to remove the cooktop from the countertop?

Not always. Many repairs can be done from above or from the cabinet below. When removal is needed, we take care to protect the counter and surrounding cabinetry.

Do Bay Area rules require me to replace my gas cooktop?

The Bay Area Air District appliance rules we follow apply to furnaces and water heaters, not cooktops, and they don't require replacing working equipment. A repaired gas cooktop can stay in service.

Are you a factory service provider for these brands?

No. We are an independent repair company and are not affiliated with or endorsed by Wolf, Sub-Zero, Viking, Thermador, or any other brand.

Cooktop Repair | Wolf Appliance

The short answer

Most high-end cooktop problems, such as weak ignition, uneven flames, dead elements, and induction errors, come from a specific part that can be tested and replaced without removing the whole unit. Repair usually makes sense on a well-built cooktop unless the surface or main control system is badly damaged and parts are hard to get.

A cooktop that won't light, clicks without stopping, or heats unevenly can throw off every meal. Wolf Appliance Services repairs gas, electric, and induction cooktops in San Jose and nearby cities, with a focus on Wolf, Viking, and Thermador models. We also service Sub-Zero refrigeration, which often shares the same kitchen. Our technicians work on built-in and professional-style units where they sit, find the actual fault, and explain your options before any repair begins. We are an independent service company and are not affiliated with or endorsed by any appliance brand.

Issues we fix

Cooktop problems usually show up in a few familiar ways. If you notice any of these, it's worth a diagnosis before the problem spreads to other parts or becomes a safety issue.

Gas burners that won't ignite, or light only after several tries
Igniters that keep clicking after the burner lights or after the knob is turned off
Flames that are yellow, uneven, lifting off the burner, or going out on low
A simmer setting that runs too hot or won't hold a steady low flame
Electric radiant elements that won't heat, won't shut off, or glow only partway
Induction zones that don't detect the pan, cut out mid-cook, or show error codes
Touch controls or knobs that don't respond, lock up, or behave erratically
Cooling fans on induction units that run constantly or don't run at all
Cracked or chipped glass-ceramic surfaces
A gas smell near the cooktop. If you smell gas, turn off the burners, leave the house, and call your gas utility or 911 before calling for repair.

What our technician checks on a built-in or professional-style cooktop

On gas cooktops, we start with the ignition system. That means the electrodes at each burner, the spark module that powers them, and the small switches behind each valve that tell the module when to spark. Constant clicking often traces back to one of those switches or to moisture from a spill. We also check burner caps and bases for correct seating, clean blocked burner ports, inspect the valves, and confirm that gas pressure and the regulator are correct. Where a model has flame-sensing or reignition features, we test those too.

On electric radiant cooktops, we test each element for continuity, then check the controls or infinite switches, the temperature limiters under the glass, and the wiring connections, which can loosen or burn over time.

On induction cooktops, we read any stored error codes, confirm the supply voltage, and test the power and generator boards, the induction coils, temperature sensors, and the cooling fan. Induction electronics need steady airflow, so we also look at ventilation clearance under the unit.

On built-in installations, how we reach the parts matters. Some cooktops lift out from above, while others are serviced from the cabinet below. We look at the cutout, the cabinetry, and any downdraft vent before deciding how to open the unit without damaging stone counters or custom panels.

How Wolf, Viking, Thermador and Sub-Zero kitchens differ

Wolf gas cooktops use sealed, stacked burners designed for both high heat and a very low simmer. When they act up, the cause is often ignition parts, a valve that no longer holds a steady low flame, or burner pieces that aren't seated correctly after cleaning. Wolf electric and induction models more often come in for control or electronic faults.

Viking cooktops, especially professional-style gas units, put a lot of heat into the cooktop body. Igniter switches, spark modules, and knob-related parts are common repairs, and heavy use can wear burner components over time.

Thermador gas cooktops are known for their star-shaped burners and low-simmer settings. Clogged burner ports and simmer control problems come up often, along with igniter issues. Thermador induction models bring the usual electronic concerns of boards, sensors, and fans.

Sub-Zero makes refrigeration rather than cooktops, but many local kitchens pair a Sub-Zero refrigerator with a Wolf cooktop or range. If both need attention, we can look at them on the same visit.

Repair or replace a high-end cooktop

Premium cooktops are built to be serviced, and most of the parts that fail, such as igniters, switches, valves, elements, and sensors, can be replaced individually. When the burners, frame, and surface are sound, repair is usually the practical choice. It also avoids changing the countertop cutout, which may not match a new model.

Replacement is worth discussing when the glass surface is badly cracked and the part is hard to find, when the main control or power boards have failed on an older model with limited parts availability, or when several major parts are failing at once. We give you a straight assessment and leave the decision to you.

What affects the cost of cooktop repair

Every repair is quoted after diagnosis, because the cost depends on a few specific things. The first is the fault itself: cleaning burner ports or reseating a part is a smaller job than replacing a valve or an induction board. The second is parts, since electronic boards and glass surfaces cost more than igniters or switches, and older or less common models can take longer to source.

Access also plays a role. A cooktop that lifts out cleanly is quicker to service than one set into stone with tight cabinetry below, a downdraft system, or custom panels that need careful handling. We explain these factors and give you a clear quote before starting work.

How a cooktop repair visit works

When you contact us, we ask for the brand, model, and symptoms so the technician arrives prepared. If you can find the model and serial number, usually on a label under the cooktop or in the cabinet below, that helps.

At the visit, the technician checks the symptom, tests the related parts, and explains what failed and why. You get a quote before any repair. Common parts can often be replaced the same day. If a part has to be ordered, we schedule a return visit to finish the job, then test every burner or zone before we leave.
