The short answer
Viking Repair Experts repairs gas, electric, and induction cooktops in Los Altos Hills (94022), including Viking, Wolf, and Thermador models. We test the burner, element, or control that is actually failing, explain what we found, and repair the part that needs it rather than recommending a new cooktop by default.
When a cooktop burner won't light, an induction zone shows an error, or a knob no longer holds a steady simmer, cooking gets harder. Viking Repair Experts repairs gas, electric, and induction cooktops in Los Altos Hills homes, with a focus on Viking, Wolf, and Thermador models. Many kitchens we visit also have Sub-Zero refrigeration, and we understand how these appliances are built to work together. We are an independent repair company based in San Jose, about 11 miles east of Los Altos Hills, and we are not affiliated with or endorsed by any appliance brand. Our job is to find out why your cooktop is acting up and explain the repair in plain terms before any work begins.
Cooktop Problems We Fix in Los Altos Hills Homes
Premium cooktops have more parts than standard ones: sealed dual-stacked burners, spark modules that relight on their own, induction boards that sense pan size, and touch controls under glass. When one of these parts fails, the symptom doesn't always point straight to the cause. A burner that clicks but won't light could have a dirty igniter, a misaligned burner cap, a weak spark module, or a gas supply issue.
These are the problems homeowners call us about most:
- Gas burners that won't ignite, light slowly, or keep clicking after the flame catches
- Uneven, yellow, or lifting flames, or a simmer that goes out on low
- Induction zones that won't detect a pan or show an error code
- Electric radiant elements that stay off, stay on, or heat only partway
- Touch controls or glass panels that don't respond or lock up
- Knobs, valves, or switches that feel loose or no longer control heat accurately

How We Work on Viking, Wolf, and Thermador Cooktops
Viking gas cooktops often run into trouble with igniters and spark modules, especially after spills reach the burner base. Wolf cooktops, whether gas or induction, are built with tight tolerances, so a slightly worn burner component or a failing control board can change how the cooktop behaves. Thermador cooktops, including models with their signature star-shaped burners, need correct burner alignment and clean ports to light reliably.
On every visit we start by confirming the symptom with you, then test the circuit, gas flow, or electronic signal involved. We look at the specific part rather than guessing. If a part needs replacing, we tell you what it is, why it failed, and whether it's practical to repair compared with the age and condition of the cooktop. If cleaning or adjusting will solve the problem, we say so.
Safety Comes First With Gas Cooktops
If you smell gas near your cooktop, turn the burners off, avoid using switches or open flames, leave the house, and call your gas utility or 911 from outside. A smell of gas is an emergency for the utility to handle before any appliance repair.
For problems that aren't emergencies, such as a burner that clicks without lighting, a flame that looks wrong, or a valve that feels stiff, stop using the affected burner until it's checked. Ignition and valve problems tend to get worse over time. Catching them early usually means a simpler repair.

Repair or Replace? Practical Considerations
Many homeowners ask whether they should repair a gas cooktop or switch to induction. The Bay Area Air District appliance rules you may have heard about cover furnaces and water heaters, not cooktops, and those rules don't require replacing working equipment. A gas cooktop that works well can usually be kept running with normal repairs.
If you are thinking about a change, we can give you an honest read on your current cooktop's condition so the decision is based on facts. Replacing a cooktop in a finished kitchen can affect cabinetry, countertop cutouts, ventilation, and electrical service. Fixing a single failed component is often the simpler path.
