The short answer
Wolf Appliance Services repairs gas, induction, and electric cooktops in Los Altos, with a focus on Wolf along with Viking and Thermador models. We diagnose the cause first, explain the repair before starting, and often finish in one visit when the part is on hand.
A cooktop that won't light, clicks nonstop, or throws an error code mid-dinner is more than an annoyance in a busy kitchen. Wolf Appliance Services repairs gas, induction, and electric cooktops in Los Altos homes. We focus on Wolf and also work on Viking and Thermador models. Many of the kitchens we visit pair a Wolf cooktop with Sub-Zero refrigeration, and we service those units too. We're an independent repair company based in San Jose, about 12 miles away, so homes in the 94024 ZIP code are a short drive.
Common Cooktop Problems We Fix in Los Altos Homes
Most cooktop calls in Los Altos come down to a handful of problems. Some are simple, like a burner cap sitting slightly off center. Others involve a failed spark module, a worn gas valve, or a control board that has stopped responding. We find the cause before recommending any part, so you know what's wrong and why.
- Igniters that click continuously, even with the knob turned off
- Burners that won't light, or light only after several tries
- Weak, yellow, or uneven flames on sealed gas burners
- Simmer settings that run too hot or let the flame go out
- Induction zones that won't heat or don't detect the pan
- Error codes, blinking indicators, or unresponsive touch controls
- Cracked or chipped glass-ceramic surfaces and loose or broken knobs
Gas, Induction, and Electric Cooktops Need Different Repairs
Gas cooktop repairs usually involve the ignition system and burner assembly. On a Wolf cooktop with dual-stacked sealed burners, for example, a burner can light on high but struggle at low settings if the lower ring's ports are clogged or the valve isn't metering gas correctly. Viking and Thermador gas cooktops have their own burner designs, and we work with each on its own terms rather than treating every burner the same.
Induction cooktops rely on electronics. They use power boards, induction coils, cooling fans, and sensors that check pan size and temperature. When an induction zone shuts off early or shows a fault, the cause is often heat-related, such as a blocked fan or vent beneath the unit. Electric radiant cooktops are more straightforward. Still, a failed element, limit switch, or infinite switch can leave a zone stuck on high or dead entirely.
What to Expect When We Come Out
We start by asking what you've noticed. We'll want to know when the problem started, whether it affects one burner or all of them, and what error codes appear on the display. On site, we test the ignition, gas flow, or electrical components and inspect the wiring and connections under the cooktop. Built-in cooktops in islands and counters can be tight to reach, so we take care to protect your countertops and cabinetry while we work.
Once we find the cause, we explain the repair and what it involves before going ahead. If the part is on the truck, we can often finish during the same visit. If it needs to be ordered, we'll tell you what to expect and schedule a return trip. If a repair doesn't make sense for an older unit, we'll tell you plainly so you can decide on next steps.

A Few Safe Checks Before You Call
Some cooktop problems have quick fixes you can try yourself. Always turn off the burner and let the surface cool before touching anything.
- Make sure burner caps and grates sit flat and centered on the burner base.
- Wipe spills from igniters and burner ports with a dry cloth. Moisture left after cleaning can cause clicking that stops once the area dries.
- For induction, confirm your pan is magnetic and sized correctly for the zone.
- Check the circuit breaker. For gas units, also confirm the cooktop is plugged in, since the igniters need electrical power.
- If you smell gas, shut off the supply if you can do so safely, leave the house, and call your gas utility before calling us.
