The short answer
Viking Repair Experts repairs Viking, Wolf, and Thermador ranges in Los Altos, CA, including burner, igniter, oven, and control problems. We diagnose the cause on site, explain your options, and repair it with parts matched to your model.
When a range stops lighting, heats unevenly, or throws an error code, the whole kitchen slows down. Viking Repair Experts repairs premium gas, dual-fuel, and induction ranges in Los Altos homes, with a focus on Viking, plus Wolf and Thermador. Many kitchens here pair those ranges with a Sub-Zero refrigerator, and we work on those too, so one visit can cover more than one appliance if needed. Los Altos is about 9 miles northwest of our San Jose base, and we serve the 94024 ZIP code and the surrounding neighborhoods. Our goal on every range call is the same: find the actual cause, explain it plainly, and fix it with parts that fit your model.
Range Problems We Fix in Los Altos Kitchens
Professional-style ranges have more going on than a standard stove: multiple burner sizes, spark modules, convection fans, and in dual-fuel models, a gas cooktop paired with an electric oven. When something goes wrong, the symptom doesn't always point to the part that failed. A burner that clicks but won't light might have a cracked igniter, a wet or dirty burner cap, or a failing spark module.
These are the issues we're most often called for:
- Burners that won't light, light slowly, or keep clicking after ignition
- Weak, yellow, or uneven flames on the cooktop
- Oven not reaching temperature, or running hot or cold
- Convection fan noise or a fan that won't turn on
- Broil or bake elements that have stopped working
- Griddle, grill, or charbroiler sections that won't heat
- Error codes, unresponsive knobs, or touch controls that don't respond
- Oven doors that don't close tightly or have worn hinges and gaskets

Viking, Wolf, and Thermador Ranges
Each brand builds its ranges differently, and that affects how we diagnose them. Viking ranges come in open and sealed burner designs, and igniter and spark module wear is a common source of trouble on both. Wolf dual-fuel ranges use dual-stacked sealed burners and an electric oven with its own controls and sensors. Thermador ranges use star-shaped burners with a low simmer setting, and a burner that won't hold a low flame usually needs a different fix than one that won't light at all.
We come prepared for the brands we see most often, and we order model-specific parts when a repair calls for them, rather than forcing in a generic substitute.
What to Expect From a Range Repair Visit
We start by asking what you've noticed: when the problem started, whether it's constant or intermittent, and anything unusual like smells, sounds, or error messages. Then we test the range directly, checking burners, ignition, oven temperature, and controls instead of guessing from the symptom.
Once we know the cause, we explain what failed, what the repair involves, and whether we can finish it that day or need to order a part. You decide how to proceed before any work begins. If a repair doesn't make sense for your range, we'll tell you that, too.

Gas Safety: When to Stop Using Your Range
Most range problems are inconvenient, not dangerous. A few signs mean you should turn the range off and keep it off until it's been checked. If you smell gas, leave the house and contact your gas utility from outside before calling for repairs.
Stop using the range and call for service if you notice any of these:
- A gas smell near the range when burners are off
- Burners that ignite with a loud pop or a delayed whoosh
- Flames that lift off the burner or spill outside the grate area
- Scorching, melted knobs, or heat discoloration on the cabinets next to the range
- An oven that keeps heating after it's been turned off
Repair or Replace?
Premium ranges are built to be serviced, and most common failures, such as igniters, spark modules, thermostats, sensors, elements, and fans, are repairable. Replacing a high-end range also often means dealing with cabinet fit, gas or electrical changes, and ventilation, so repair is usually the more practical path.
Replacement is worth discussing when a range has several major parts failing at once, when a needed part is no longer available, or when the cooktop or oven body itself is damaged. We'll give you a straightforward read on where your range stands so you can decide.
