The short answer
Wolf Appliance Services repairs gas, electric, and induction cooktops in Los Altos Hills, with a focus on Wolf and also Viking and Thermador models. We find the actual fault, from igniters and valves to control boards, and test the cooktop at every setting before we leave.
A cooktop that won't light, clicks endlessly, or heats unevenly turns dinner into a workaround. Wolf Appliance Services repairs gas, electric, and induction cooktops and rangetops in Los Altos Hills homes, with a focus on Wolf equipment. We also work on Viking and Thermador cooktops, and on the Sub-Zero refrigeration that often shares the same kitchen. Our base is in San Jose, about 14 miles east of town, so Los Altos Hills (94022) is a regular stop on our routes through Santa Clara County. We are an independent repair company and are not affiliated with any appliance brand.
Cooktop problems we fix in Los Altos Hills kitchens
Many kitchens are built around a professional-style cooktop or rangetop, such as a Wolf gas unit with sealed burners or a Thermador or Viking model with high-output burners. These appliances are built to last, but their igniters, valves, and control boards still wear out. The problems we handle most often include:
- Burners that click but won't light, or light only after several tries
- Continuous clicking after the flame is on, often from moisture or a failing spark module
- Weak, yellow, or uneven flames caused by clogged burner ports or misaligned caps
- Low simmer settings that go out or run too hot
- Induction zones that show error codes, don't detect the pan, or shut off mid-cook
- Electric radiant elements that stay cold or won't turn off
- Cracked glass or ceramic surfaces and loose or broken knobs
How we diagnose gas, electric, and induction cooktops
Each cooktop type fails in its own way, so we confirm what's actually wrong before replacing anything. On gas models, we check the igniters, spark module, burner heads, gas valves, and flame-sensing parts, and we test gas flow and ignition timing. If we find a leak or a problem with the household gas supply, we'll tell you plainly and shut the appliance off if needed.
Induction and electric cooktops need electrical testing. We check supply voltage, the control and power boards, cooling fans, temperature sensors, and touch controls. Induction units are sensitive to heat buildup, so a blocked vent or failing fan can cause shutdowns that look like a board problem. Finding the true cause keeps you from paying for parts you don't need.
After a repair, we run the cooktop through its settings, from full power down to the lowest simmer, so you can see it working before we leave.
What to check before you call
A few quick checks can save a visit or help us arrive with the right parts:
If you smell gas, don't troubleshoot. Leave the house and contact your gas utility first.
- Make sure burner caps sit flat and centered; an off-center cap is a common reason a gas burner lights unevenly.
- Let a recent spill dry completely. Water around an igniter can cause clicking that stops once it dries.
- For induction, confirm your cookware is magnetic. A magnet should stick firmly to the bottom of the pan.
- Check the circuit breaker if an electric or induction cooktop is completely dead.
- Write down the model and serial number, usually on a label under the cooktop or on the burner box, and note any error code.

Serving Los Altos Hills and nearby towns
If your property has a gate, a long driveway, or a separate service entrance, share those details when you book. Clear directions and any access codes help us arrive on time and spend the visit on your cooktop instead of finding the door.
From our San Jose base, we also serve nearby Los Altos, Mountain View, Cupertino, Sunnyvale, and Saratoga. If other appliances in your kitchen are acting up, such as a Wolf wall oven or a Sub-Zero refrigerator, mention them when you schedule so we can look at them during the same trip.
Repair or replace your cooktop?
Premium cooktops are usually worth repairing. Igniters, spark modules, valves, knobs, and many control boards are replaceable parts, and fixing them keeps a well-built appliance in service. Replacing a built-in cooktop can also mean countertop work if the new model's cutout doesn't match the old one.
Replacement starts to make sense when the glass top is badly cracked on an older unit, when parts are no longer available, or when several major components have failed at once. If you're weighing a switch from gas to induction, we can tell you the condition of your current cooktop so you can decide based on facts. We'll give you an honest read either way.
