When a burner won't light, a clicking igniter won't stop, or an induction zone throws an error code, cooking dinner gets complicated fast. Sub-Zero Service Center repairs premium cooktops in Rolling Hills Estates homes, about 3 miles west of our base in Wilmington. Many kitchens here pair a Sub-Zero refrigerator with a cooktop from Wolf, Viking, or Thermador, and we work on all four brands. We are an independent repair company, not affiliated with any manufacturer. This page covers the cooktop problems we see most, what you can check before calling, and what a service visit involves.
Common Cooktop Problems We Fix
Premium cooktops are built to last, but parts that handle heat, flame, and moisture wear out eventually. Most service calls come down to a handful of recurring issues. Knowing the symptom helps us bring the right parts on the first trip.
Gas rangetops and cooktops from Wolf, Viking, and Thermador use sealed burners with electronic ignition. When ignition fails, the cause can be as simple as a misaligned burner cap or as involved as a failing spark module. Electric and induction models have their own failure points, usually in elements, sensors, or control electronics.
- Igniter that clicks constantly, even with the knob off
- Burner that sparks but won't light, or lights and then goes out
- Weak, uneven, or yellow flame instead of a steady blue one
- Low simmer settings that won't hold a gentle flame
- Radiant element that stays cold or won't shut off
- Induction zone that doesn't detect cookware or shows an error code
- Touch controls that are unresponsive or behave erratically
- Cracked glass or ceramic cooktop surface
What to Check Before You Call
A few quick checks can save you a service visit, or at least help us narrow down the problem. Always let the cooktop cool fully before touching burners or the surface.
On gas models, remove each burner cap and grate, clean away food residue or boilover, and make sure the cap sits flat and centered on its base. A cap that is slightly off often causes poor ignition or an uneven flame. Moisture from cleaning can also cause constant clicking; letting the burner dry for a few hours sometimes solves it.
On electric and induction cooktops, check your breaker panel first. For induction, confirm your pan is magnetic by testing it with a fridge magnet, since non-magnetic cookware won't register. If an error code appears, note it exactly and share it when you contact us.
How a Cooktop Repair Visit Works
Our technician starts by confirming the symptom with you and testing the cooktop in operation. For gas units, that means checking ignition, flame quality, and gas valve function at each burner. For electric and induction units, we test elements, sensors, wiring, and control boards with a meter rather than guessing.
Once we find the cause, we explain what failed and what the repair involves before any work begins. Many common parts, such as igniters, spark modules, and burner components, can be replaced during the same visit. Brand-specific parts like control boards or induction generators sometimes need to be ordered, and we schedule a return visit when they arrive.
If you smell gas strongly at any point, turn off the cooktop, leave the house, and contact your gas utility or emergency services before calling a repair company.
