The short answer
Yes, we repair gas, dual-fuel and electric ranges in Hidden Hills, including Wolf, Viking and Thermador models, and we come out from our Van Nuys base about 11 miles away. Most range problems trace back to a specific part, such as an igniter, sensor, element, fan or control, that can be tested and replaced.
A range sits at the center of how a household cooks, so when a burner won't light or the oven runs cold, dinner plans change quickly. Sub-Zero Appliance Repair is an independent service company based in Van Nuys, about 11 miles east of Hidden Hills. We diagnose and repair the premium ranges found in many local kitchens. Our work includes Wolf, Viking and Thermador ranges and rangetops, and we also service the Sub-Zero refrigeration that is often installed next to them. This page covers range repair only: what tends to go wrong, how we track it down, and what to expect when we come out.
Range problems we see in Hidden Hills kitchens
Large professional-style ranges get heavy use, and they show wear in predictable places. Many homeowners call us for one of the issues below. Each one has a short list of likely causes, which we check in order instead of guessing.
- A burner clicks but won't light, or keeps clicking after the flame is on
- A weak, uneven or yellow-tipped flame on one or more burners
- The oven takes much longer to preheat or never reaches the set temperature
- Baked goods brown on one side or come out underdone
- The convection fan is noisy or doesn't run
- The self-clean cycle won't start, or the door stays locked afterward
- Error codes, a dead display, or knobs and controls that don't respond
Burner and ignition repair on Wolf, Viking and Thermador rangetops
Most cooktop complaints are ignition complaints. A burner that clicks without lighting may have a cracked or dirty igniter, a burner cap that isn't seated flat, or moisture from a boil-over or a recent cleaning. Constant clicking after the burner lights often points to a wet or failing switch behind the knob, or a spark module that needs testing.
Flame problems are a different job. A low or lazy flame can come from clogged burner ports or an orifice issue. A yellow, floppy flame can mean the air-to-gas mix is off. We clean, adjust or replace the parts involved, then light every burner across its full range, from simmer to high, before we leave.
Oven temperature, convection and self-clean repairs
When an oven won't heat, the cause depends on the fuel. In a gas oven, a weakened igniter can glow but never draw enough current to open the gas valve. That is one of the most common failures we see, and we confirm it with a meter rather than by eye. Electric and dual-fuel ovens more often have a failed bake or broil element, a faulty temperature sensor, or a relay on the control board.
Uneven baking usually means a convection fan motor or fan element problem, or an oven that has drifted out of calibration. Self-clean faults tend to involve the door lock assembly or its switch. Because self-clean runs at very high heat, we also check door gaskets and hinges for wear while we're in there.

What to expect from a visit to Hidden Hills
We drive out from Van Nuys, so it helps to have the brand, model and serial number ready when you book. On most ranges that tag sits behind the kickplate, inside the oven door frame, or under a burner grate. If your street requires gate access, tell us when you schedule so the technician can get to your door on time.
At the visit we test the symptom, explain what failed and why, and lay out your options before any work begins. Some parts for Wolf, Viking and Thermador ranges are brand-specific and may need to be ordered. If so, we'll tell you plainly and set up a return trip. We also serve nearby Calabasas, Santa Monica, San Fernando, Beverly Hills and West Hollywood.
When to stop using the range
Some problems shouldn't wait for an appointment. If you smell gas, don't operate any switches or burners. Leave the house and contact your gas company or 911 from outside. Once the gas service is cleared, we can diagnose the range itself. You should also turn the range off and leave it off if you see scorching around the knobs, sparking inside the oven, or a door that won't close on a hot oven.
