The short answer
Yes, we repair gas, dual-fuel and electric ranges in Calabasas (91302), focusing on Wolf, Viking and Thermador models in kitchens that often include Sub-Zero refrigeration. Most range problems trace back to igniters, spark modules, burners, temperature sensors, fans or controls. We test these parts in your kitchen before recommending a repair.
A professional-style range is often the hardest-working appliance in a Calabasas kitchen. When a burner won't light or the oven won't hold temperature, cooking stops. Sub-Zero Appliance Repair is an independent service company based in Van Nuys, about 12 miles northeast of Calabasas. We repair gas, dual-fuel and electric ranges in premium kitchens. That includes the Wolf ranges often installed alongside Sub-Zero refrigeration, as well as Viking and Thermador models. This page covers the range problems we diagnose in the 91302 area and how to prepare for a visit.
Range problems we see in Calabasas kitchens
A large range with six or eight burners, a griddle or charbroiler, and one or two ovens has more parts that can wear out than a standard stove. Most range repair calls come down to a short list of symptoms, and each one points to a different set of components.
Some fixes are simple. A burner cap that sits crooked after cleaning will cause an uneven flame. Others take testing. An oven that slowly loses the ability to reach temperature often has a gas oven igniter or temperature sensor that checks out fine when cold and fails under heat. That's why we test components while the range is running instead of guessing from the symptom.
- Constant clicking after a burner lights, often caused by a spill or moisture on the spark igniter, a cracked igniter or a failing spark module
- A burner that clicks but won't light, or only lights on high
- Weak, yellow or uneven flames, which can come from clogged burner ports, a misaligned cap or a gas pressure problem
- An oven that heats slowly, won't reach the set temperature, or runs hot
- A convection fan that is noisy or doesn't turn
- Error codes, a blank display, or controls that don't respond
- A self-clean cycle that won't start, or a door that stays locked afterward
- Griddle or charbroiler sections that heat unevenly

Notes on Wolf, Viking and Thermador ranges
Calabasas kitchens built or remodeled around a Sub-Zero refrigerator often pair it with a Wolf range, because both come from the same manufacturer group. Wolf dual-fuel ranges have sealed gas burners on top and an electric oven below. On those models, an oven complaint means checking the heating elements, the convection system and the control, not a gas igniter. Wolf all-gas ranges have a gas oven with its own ignition and safety valve, which we test separately.
Viking ranges are common in homes that went for a commercial look. Depending on the model, they may have sealed or open burners, a griddle or grill section, and heavy oven doors. On Viking ranges that have seen years of daily use, door hinges, door gaskets and oven igniters are worth checking.
Thermador ranges use star-shaped burners, and many models have a low-simmer setting that cycles the flame on and off. A simmer burner that keeps shutting off may be working normally, or it may have a valve or ignition fault. We test it so you know which.
If you smell gas or the flame looks wrong
If you smell gas near the range, don't try to troubleshoot it. Turn off the burners if you can do so safely. Don't switch lights or appliances on or off. Leave the house, then call your gas utility or 911 from outside. Once the gas side has been checked and cleared, we can come out to repair the appliance.
Some problems don't call for leaving the house but still need attention. Watch for a flame that lifts off the burner, heavy soot, or a burner that lights with a loud pop. Turn that burner off and leave it off until it has been inspected.

What happens during a range repair visit
Our technician starts by confirming the symptom with you, then tests the parts involved. That can include checking the igniters and spark, gas valve operation, and oven temperature against a separate thermometer. We also take readings on elements and sensors and check the outputs from the control.
If a part needs replacing, we explain what failed and why and go over your options before any work begins. Many premium range parts are specific to one model, so some repairs need a second visit once the part arrives. Along with Calabasas, we serve Hidden Hills, Santa Monica, Beverly Hills, Los Angeles and San Fernando.
Getting ready for the appointment
A few details help us come prepared. Please don't run a self-clean cycle to try to reset an oven that is acting up. The high heat can make an existing fault worse.
- The brand and model number from the rating label. Its location varies by model; check the oven door frame, behind a lower panel, or along the side of the range.
- Whether the range is all-gas, dual-fuel or electric
- What happens and when: at startup, at a certain temperature, or only on one burner
- Any error codes shown on the display
- Clear access to the range and the floor space in front of it
