The short answer
Wolf Appliance Services repairs Wolf, Viking, and Thermador ranges in Campbell, CA, including burners that won't light, igniters that keep clicking, ovens that won't heat, and faulty controls. We diagnose the problem in your kitchen and explain the repair options before starting work.
When a high-end range stops working, cooking at home stops too. Wolf Appliance Services repairs premium gas, dual-fuel, and induction ranges for homeowners in Campbell, CA (ZIP 95008). We are about 4 miles northeast in San Jose, so Campbell is a short drive for us. We lead with Wolf ranges and rangetops, and we also service Viking and Thermador ranges. Many of the kitchens we visit also have a Sub-Zero refrigerator, which we can look at during the same trip. We are an independent repair company. We are not affiliated with or endorsed by any of these brands.
Range Problems We Fix in Campbell Homes
Premium ranges use sturdy components, but parts still wear out. Most range calls we get from Campbell fall into a few familiar patterns. Some are cooktop problems, some are oven problems, and some are electronic.
On gas and dual-fuel models, the cooktop and the oven often have separate causes. A range can have a perfect oven and one burner that won't light, or the reverse. We test each section on its own so we only replace what has actually failed.
- Burners that click but won't light, or light only after several tries
- Igniters that keep clicking after the burner is lit, often after cleaning or a spill
- Weak, yellow, or uneven flames on sealed burners
- Ovens that won't heat, heat slowly, or run hotter or cooler than the setting
- Convection fans that are noisy or don't turn on
- Broiler problems, bake element failures, and slow-glowing oven igniters
- Control boards, knobs, and display errors on dual-fuel and induction models
- Oven doors that won't seal, hinges that sag, and self-clean locks that stay latched

Wolf, Viking, and Thermador Ranges
Wolf ranges are the core of our work. These include the dual-fuel models with dual-stacked sealed burners and the all-gas ranges, as well as rangetops and built-in cooktops. Several Wolf symptoms show up again and again. Spark modules click continuously when moisture reaches the burner area. Oven temperatures drift and need calibration. Igniters weaken over time.
We also repair Viking ranges and Thermador ranges, including Thermador models with star-shaped burners. Each brand routes its gas valves, igniters, and electronics differently, so we approach each one according to its own design rather than treating every range the same.
Our technicians can also look at Sub-Zero refrigeration while they are in your kitchen. Just tell us when you book.
What to Check Before You Call
A few quick checks can save you a visit, or at least speed up the repair.
Safety comes first. If you smell gas, do not light anything or operate switches. Leave the house and call your gas utility or 911 from outside. Range repair begins once the home is safe.
- Make sure the range is plugged in and the breaker hasn't tripped. Gas ranges still need power to spark.
- If a burner clicks nonstop after cleaning, remove the caps and let the burner area dry completely before trying again.
- Check that burner caps and grates sit flat and are seated correctly.
- Write down any error code or blinking light on the display.
- Note your model and serial number, usually found on a label near the oven door frame or behind a kick panel.
Tell us what your appliance is doing.
How a Range Repair Visit Works
We start by confirming the symptom with you and testing the range. That means lighting burners, measuring oven temperature, and checking voltage and gas flow where needed. Then we explain what we found and what the repair involves, so you can decide how to proceed before we do any work.
Some repairs can be finished during the first visit. Others need a part ordered for your specific model. In that case we schedule a return visit once the part arrives. When the work is done, we test the range again to confirm the burners light cleanly and the oven holds temperature.
