The short answer
Sub-Zero Service Center repairs gas, electric, and induction cooktops in Rancho Palos Verdes, including Wolf, Viking, and Thermador models. We diagnose the specific failed part, such as an igniter, spark module, valve, element, or control board, and explain what's wrong before any repair begins.
A cooktop that clicks but won't light, burns unevenly, or flashes an error code can take a kitchen out of service. Sub-Zero Service Center repairs premium gas, electric, and induction cooktops and rangetops in Rancho Palos Verdes homes throughout ZIP code 90275. We're based about 6 miles northeast in Wilmington, so the peninsula is a short drive for us. Our name leads with Sub-Zero refrigeration, but many kitchens built around a Sub-Zero refrigerator also have a premium cooktop, and we regularly work on Wolf, Viking, and Thermador models. We're an independent repair company and are not affiliated with any appliance brand.
Gas cooktop and rangetop problems we fix
Most gas cooktop calls come down to ignition, gas flow, or controls. High-output burners on Wolf, Viking, and Thermador models use precise parts, and a small problem like a cracked igniter or a misaligned burner cap can make a burner unreliable. We test each part before replacing anything, so you aren't paying for guesses.
- Igniters that click constantly or won't stop clicking after the burner lights
- Burners that won't light, or that light and then go out
- Weak, yellow, or uneven flames
- Low simmer settings that won't stay lit
- Knobs or valves that are stiff, loose, or hard to set
- Spark modules that have failed or are sparking on every burner at once

Electric and induction cooktop repair
Smooth-top electric and induction cooktops fail differently from gas units. An electric element may stop heating or stay on high, and an induction zone may refuse to recognize a pan or show a fault code. These problems usually trace back to an element, a power board, a touch control, a temperature sensor, or the wiring between them.
We check the incoming power, read any error codes, and test the parts that control the affected zone. If the glass top is cracked, we'll tell you plainly whether the unit is safe to use and what replacing the glass involves for your model.
Coastal homes and cooktop wear
Rancho Palos Verdes sits close to the ocean, and homes near the coast stay milder and often damper than inland neighborhoods. Moisture and salty air can be hard on exposed metal parts over time. On gas cooktops, igniters and burner parts can pick up residue that weakens the spark, and spill-overs can make it worse. Cleaning and drying the burner area properly prevents many repeat ignition problems, and we'll show you what to watch for on your model.
Some cooktops in the area are paired with downdraft vents or sit in large islands, which affects how we reach the parts underneath. We plan for that access before we start taking anything apart.

What a service visit looks like
When you contact us, tell us the brand, the model number if you can find it, and exactly what the cooktop is doing. That helps us bring the most likely parts. At your home, we confirm the symptom, test the related components, and explain what failed and why. You decide whether to go ahead before any repair begins.
If a part has to be ordered, we tell you so and schedule a return visit to finish the job. After the repair, we test every burner or zone, not just the one that was acting up.
When to stop using the cooktop
Some problems shouldn't wait for an appointment. If you smell gas, don't use the cooktop or operate light switches; leave the house and call your gas utility from outside. Once the gas side is confirmed safe, we can repair the appliance.
- A gas smell near the cooktop
- A burner that lights with a loud pop or a delayed whoosh
- A cracked glass top on an electric or induction unit
- Controls that turn on by themselves or won't turn off
- Scorching, melting, or a burning-plastic smell from under the cooktop
