The short answer
Viking Appliance Services repairs gas, electric, and induction cooktops in South Pasadena, including Viking, Wolf, and Thermador models. Most problems trace back to igniters, burner parts, heating elements, or control boards. We diagnose the cooktop at your home and explain the repair before any work begins.
When a burner won't light or an induction zone stops responding, cooking dinner gets complicated fast. Viking Appliance Services repairs gas, electric, and induction cooktops in South Pasadena homes in the 91030 ZIP code. We focus on premium brands: Viking first, plus Wolf and Thermador cooktops, and the Sub-Zero refrigeration that often shares the same kitchen. We're an independent repair company based in Los Angeles, about 14 miles away, so South Pasadena is a regular part of our service area. This page covers the cooktop problems we see most, what you can check before booking, and what to expect when a technician comes out.
Cooktop Problems We See in South Pasadena Kitchens
Most cooktop calls fall into a handful of patterns. Some are simple, like a burner cap seated slightly off center. Others point to a failing part that needs to be tested and replaced. Here are the issues homeowners describe most often:
- Constant clicking from the igniters, even with every knob turned off
- A burner that clicks but never lights, or lights and then goes out
- Weak, yellow, or uneven flames on one or more burners
- An electric or induction zone that won't heat, or heats only on high
- Touch controls that don't respond, lock up, or show an error code
- Cracked or chipped glass-ceramic surfaces
- Knobs that spin loosely or no longer turn the burner on and off
Gas Cooktop Repair for Viking, Wolf, and Thermador
Premium gas cooktops use sealed burners with electronic spark ignition, and most of the trouble starts there. On a Viking or Wolf cooktop, a burner that keeps clicking after it lights usually means the reignition system isn't sensing the flame. Common causes are moisture, a cracked igniter, or a worn spark module. Boil-overs are a frequent trigger: liquid gets under the burner base, and the igniter keeps firing until it dries out. If the clicking continues for more than a day after a spill, a part may have shorted.
Thermador's star-shaped burners and Wolf's dual-stacked burners are built to run from a low simmer up to high heat. When the low setting won't hold, or the flame lifts and sputters, we check the burner ports, the valve, and the gas supply pressure before recommending any part. Clogged ports can sometimes be cleaned. A faulty valve or spark module needs to be replaced.
If you smell gas, don't try to diagnose it yourself. Turn off the cooktop if it's safe to do so, leave the house, and call your gas utility or 911 from outside. Once the utility has cleared the situation, we can repair the cooktop.
Electric and Induction Cooktop Repair
Electric radiant and induction cooktops fail in different ways. On a radiant cooktop, a zone that won't heat usually comes down to the heating element, the infinite switch or control board, or a loose wire connection. A zone stuck on high often points to a failed switch or relay.
Induction cooktops rely more heavily on electronics. Error codes, a fan that runs without heating, or controls that shut off mid-cook can trace back to a power board, a cooling fan, or an overheat sensor. Sometimes the cause is simply cookware the cooktop doesn't recognize. We test components with a meter rather than swapping parts on a guess, so the repair stays focused on what actually failed.
Cracked glass is a safety issue on any electric cooktop because spills can reach live components. Stop using the cooktop and switch it off at the breaker until the top is replaced.

Quick Checks Before You Schedule
A few minutes of checking can save you a visit. At the least, it gives the technician useful information:
- Confirm the breaker hasn't tripped. On gas models, make sure the cooktop is plugged in, since the igniters need electrical power.
- Lift each burner cap and head, wipe away debris, and make sure everything is dry and sitting flat.
- Try a different burner or zone to see whether the problem affects one spot or the whole cooktop.
- Check whether a control lock or child lock is turned on.
- Write down any error code, along with the model and serial number. These are usually on a label under the cooktop or on the burner box.
What to Expect From a Service Visit
A technician comes to your South Pasadena home, asks what you've noticed, and runs a full diagnosis on the cooktop. We explain what we found and what the repair involves before any work begins. Many common parts can be replaced in a single visit. If a brand-specific part has to be ordered, we schedule a return trip once it arrives.
Many cooktops are built into custom counters or islands, so we work carefully around stone and cabinetry and leave the area clean. We also serve nearby Alhambra, San Marino, Pasadena, Glendale, and Sierra Madre, so friends and neighbors in those cities can get the same service.
