The short answer
Sub-Zero Appliance Repair diagnoses and repairs gas, electric, and induction cooktops from Wolf, Viking, and Thermador in San Fernando (ZIP 91340). We find the specific failed part, explain your options, and complete the repair in your kitchen whenever that's practical.
When a burner won't light, an induction zone throws an error code, or a radiant element stays dark, it's hard to cook the way you normally do. Sub-Zero Appliance Repair fixes high-end cooktops in homes across San Fernando, about 6 miles north of our Van Nuys base. Many kitchens here pair Sub-Zero refrigeration with a Wolf, Viking, or Thermador cooktop, and those cooktops are built differently from standard models. We are an independent repair company, not affiliated with any appliance brand. We focus on finding the actual fault, explaining it in plain terms, and fixing it so your cooktop works safely again.
Cooktop Problems We Fix in San Fernando Homes
Premium cooktops usually fail in a handful of predictable ways. Knowing the symptom helps us bring the right parts and spend less time hunting for the cause.
- Gas burners that click but won't light, or light and then go out
- Constant clicking from spark igniters after a burner is lit
- Weak, uneven, or yellow flames instead of a steady blue flame
- Induction zones that don't detect a pan or flash an error code
- Radiant or electric elements that won't heat or won't turn off
- Touch controls that don't respond, or knobs that feel loose or slip
- Cracked or chipped glass-ceramic surfaces
Gas, Electric, and Induction: Different Faults, Different Fixes
Gas cooktops, including the sealed-burner and dual-stacked designs found on many Wolf and Thermador models and the high-output burners on Viking units, depend on clean burner ports, properly seated caps, working igniters, and spark modules. A burner that clicks without lighting is often a dirty or wet igniter, a misaligned cap, or a failing spark module. Grease and boil-overs are frequent causes, so we inspect and clean the burner assembly before replacing anything.
Electric radiant cooktops use heating elements, limiters, and infinite switches or electronic control boards. When one element is dead and the others work, the problem is usually that element or its switch. When several fail at once, we look at power supply, wiring, and the control board.
Induction cooktops are mostly electronics. Error codes, zones that won't recognize cookware, and cooling fans that run nonstop typically point to sensors, power boards, or overheating from blocked ventilation under the counter. We check cookware compatibility first, since a pan that isn't magnetic or doesn't sit flat can look like a fault.
What to Expect From a Repair Visit
We start by asking what you've noticed: when the problem began, whether it's every burner or just one, and any error codes shown on the display. On site, we test the cooktop under real operating conditions, measure electrical components, and inspect gas burners and connections.
Once we've found the cause, we explain what failed, what replacing it involves, and whether the part is commonly stocked or has to be ordered. If a repair doesn't make sense for an older unit, we'll tell you that directly so you can decide what to do. Many cooktops in San Fernando's 91340 ZIP code are built into custom counters, so we work carefully around stone and cabinetry when removing a unit for service.

Safety Steps Before We Arrive
If you smell gas near your cooktop, don't use any burners or switches. Leave the house and call your gas utility from outside. We repair cooktops. We don't respond to active gas leaks.
For other problems, a few simple checks can help. Make sure burner caps are dry and seated flat, confirm the circuit breaker hasn't tripped, and for induction, test with a pan you know works. Write down any error codes. If a glass surface is cracked, stop using that area, because heat and spills can reach the electronics underneath.
