About this service
Two Wolf cooktop platforms. Two entirely different service playbooks.
Wolf makes cooktops on two fundamentally different technologies. The CT Series is gas, dual-stacked sealed burners in a drop-in or recessed cooktop configuration, the same combustion architecture as the Wolf Pro range with the rangetop separated from the oven below. The ICBCT Series is Freedom Induction, 56 inductor coils under a single ceramic glass panel, sensor grid that detects cookware position, full-surface flexible cooking zones, dual inverter boards driving the coil array. Technologically, these are different appliances that share nothing internally.
What that means for service: a technician needs to know which platform you have before diagnosis starts. Gas CT failures are burner, igniter, spark module, valve. ICBCT failures are inverter boards, sensor grids, thermal protection, touch control. The diagnostic approach is completely different and the parts inventory is completely different. Shops that dispatch the same technician to both platforms and hope for the best get mixed results, we send technicians with the right training for the platform you have.
Most Wolf cooktop installs across our service area are in kitchens where a Wolf rangetop or range wouldn't fit, condominiums with tighter plan dimensions in Westwood, Newport Beach, and Marina del Rey; second kitchens and butler's pantries in Beverly Hills, Newport Coast, and Westlake Village estate homes; and covered outdoor kitchens in Calabasas, Coto de Caza, and Rancho Cucamonga (covered installs only, Wolf cooktops aren't rated for true outdoor use). The cooktop sits on the counter with a separate wall oven below, rather than the integrated range configuration.
Platforms
Wolf cooktop platforms we service
CT Gas Sealed-Burner (30" and 36")
CT30G · CT30GS · CT36G · CT36GS · CT15G
Gas sealed-burner cooktops. Same dual-stacked burner architecture as the Wolf Pro range, upper high-output tier (up to 20,000 BTU), lower simmer tier (down to 500 BTU). Cast-iron continuous grates, sealed burner pans for spill containment, recessed design for flush counter installation. 15" two-burner models for cooktop modules.
ICBCT Freedom Induction (30" and 36")
ICBCT30IU · ICBCT30IUS · ICBCT36IU · ICBCT36IUS · ICBCT30IX
Full-surface induction, 56 inductor coils under a single ceramic glass, sensor grid that detects cookware position and shape anywhere on the surface. Dual inverter boards, flexible cooking zones, touch control strip across the front. 30" and 36" widths. The most technologically advanced Wolf cooktop, and the platform that requires specialist service.
Electric Coil Cooktops (Legacy)
CER30 · CER36 · CE365T
Pre-induction electric cooktops with exposed coil elements. Still found in older Westside LA, Pasadena, North Tustin, and Riverside-area kitchens. Simple service profile, element replacement, infinite switch, hot surface indicator. Parts availability is case-by-case from Sub-Zero/Wolf distribution, older CER models (1990s–early 2000s) sometimes have discontinued switches.
Gas Rangetop (SRT Series, see Range page)
SRT486C · SRT484CG · SRT364G · SRT304
Wolf's 48", 36", and 30" gas rangetops, similar architecture to CT cooktops but with six burners plus optional infrared charbroiler or griddle. Covered in detail on our Wolf Range page rather than here, since rangetops are typically paired with wall ovens rather than operating as standalone cooktops.
Pre-2005 Wolf cooktops, we service case-by-case when Sub-Zero/Wolf parts distribution still has inventory. Certain very early ICBCT induction models (pre-2012) have discontinued inverter modules and are effectively unserviceable. We'll tell you on the phone whether your unit is economically repairable before dispatching.
Gas cooktop failures, CT Series
Common problems on Wolf CT gas cooktops
1. Burner won't ignite, clicks but no flame
Igniter or electrode problem on that specific burner. In order: clear the burner port with a thin wire (food debris blocks gas feed to the igniter), dry any moisture around the electrode area (common along the coastal-humidity corridor, Malibu, Pacific Palisades, Newport Coast, Laguna Beach), check the electrode for cracked ceramic insulator ($85 replacement), test the surface igniter with a meter ($185–$275 replacement). 40-minute service call in most cases.
2. Burner clicks continuously after lighting
Spark module doesn't detect flame, keeps firing. Most common: moisture in the electrode sense area, sparker fires until flame is detected through the flame-sense circuit. Drying the electrode solves it (15-minute fix if that's the cause). Second cause: failed spark module stuck in continuous-fire mode, $285–$425 replacement. We test with a meter before swapping.
3. Orange flame, yellow tips, or flare-up
Incomplete combustion. Clogged gas port is the first suspect, clear with 0.6mm needle. If cleaning doesn't resolve: air shutter drift or wrong inlet pressure. Wolf CT manifold wants 5–6" WC for natural gas, 10" WC for LP. We verify with a manometer and swap the regulator if inlet pressure is off ($220–$290). Orange flame running for months deposits soot on the burner and accelerates igniter failure, fix it promptly.
4. Two adjacent burners dead, no spark, no gas
Valve-bank failure. Wolf CT sealed burners are paired on the manifold, each pair sharing a valve assembly. When both burners in a pair go dark at once, it's the valve block, not the individual burners. Safety cutoff sometimes locks out the whole bank after flame-out on one burner. We reset, test, and replace the valve assembly if needed. Parts $285–$440, labor about an hour.
5. Lower simmer tier won't hold low heat
Dual-stacked burners have separate orifices for high and simmer tiers. When the simmer won't hold, pan still boils at the low knob setting, it's usually a clogged simmer orifice or a valve drifted out of calibration. Simmer orifices are small parts ($45–$85, LP or natural gas specific). Cleaning sometimes works; replacement is more reliable. Valve recalibration on-site for simple drift.
Induction cooktop failures, ICBCT Freedom
Common problems on Wolf Freedom Induction cooktops
1. "No pan" on a pan that's there
Three causes. First and most common: cookware isn't induction-compatible, magnet test should show the pan holding firmly to the magnet. Aluminum, copper, and non-magnetic stainless all fail. Second: moisture fogging the underside of the glass over the sensor grid, clears on its own after a few minutes of dry operation. Third: sensor grid drift on the ICBCT itself, persistent false "no pan" with known-good cookware. Sensor module replacement runs $560–$820 OEM; we carry on the truck. 90-minute job because the cooktop has to come out partially to access the sensor assembly.
2. Zones shut off during high-power cooking or after Boost mode
Thermal protection cutting zone power because inverter boards are overheating. Cooling fans at the rear aren't moving enough air. First suspect every time: clogged fan intake grille, lint, dust, pet hair, grease vapor. Cleaning intake vents resolves 60% of thermal-cutoff calls with no parts. If cleaning doesn't hold, fan motor replacement $240–$340. End-of-life inverter board replacement $720–$1,050 per board, some ICBCT have two inverters and when one ages the other usually follows within 12 months, so we sometimes recommend replacing both together.
3. Touch controls unresponsive or locked out
The capacitive touch strip runs along the front of the ICBCT. Failures: child lock active (hold the control symbol for 5 seconds to release), liquid on the panel causing false inputs (wipe clean, wait for full dry, recalibrate), or touch ribbon cable failure (no inputs register). Ribbon cable replacement $285–$380. Cooktop has to come out partially for access, 90-minute job total.
4. Single zone silent, others work fine, or erratic zone power
Inverter board failure. ICBCT uses dual-inverter architecture, each inverter board drives a group of coils. When one inverter dies, the coils it drives go silent while the rest of the cooktop works normally. Diagnostic: watch which coils respond to known-good cookware placement, silent zones map to the failed inverter. Inverter replacement $720–$1,050 per board. On older ICBCT units, we usually recommend replacing both inverters to avoid a second service visit 12 months later.
5. E-code errors on the display
ICBCT error codes map to specific hardware faults, E1 is communication loss between control and inverter, E3 is sensor grid fault, E6 is inverter over-temperature. About 45% of E-codes resolve without an inverter swap, sensor cleanup, connection reseat, firmware update. We carry the service documentation and diagnose by code rather than swapping components on spec.
6. Cracked ceramic glass surface
Expensive repair, the ICBCT glass has the 56-coil sensor grid bonded to the underside. Replacement means replacing both ceramic panel and sensor assembly together. Part cost $780–$1,150 OEM. Labor 2 hours (cooktop comes out, new assembly installs, sensor grid gets calibrated on reinstall). We don't recommend DIY, frame gaskets have to reseat correctly to keep liquid out of the inverter compartment below, and a bad seal leads to catastrophic water damage.

Warranty context
Inside the warranty window? Call Sub-Zero/Wolf first
Wolf cooktop warranty is 2 years on major components, burners, inverter boards, sensor grids, controls. During the warranty window, call Sub-Zero/Wolf customer service at 1-800-222-7820 for Factory-Certified dispatch at no parts cost.
Post-warranty, or when the 5-day Factory-Certified window doesn't fit your schedule, we're the better call. Particularly on ICBCT Freedom Induction, where platform-specific experience matters. ICBCT service done wrong becomes a three-visit repair cycle; done right closes in one visit with the right parts on the truck. Same training, faster response, lower labor rate than warranty dispatch.

Wolf cooktop repair, common questions
What's the difference between CT and ICBCT Wolf cooktops?
CT = gas sealed-burner, dual-stacked burner technology. ICBCT = Freedom Induction, 56 coils under ceramic glass with sensor grid. Completely different platforms internally, different diagnostic trees, different parts. Technician needs to know which you have before service starts. CT 30/36 inch widths in drop-in or recessed, ICBCT 30/36 inch in flush-mount only.
My Freedom Induction says "no pan" on a real pan
Three causes. First, cookware isn't induction-compatible, magnet test: should stick firmly to the pan bottom. Second, moisture fogging glass over sensor grid, clears after dry operation. Third, sensor grid drift, persistent false "no pan" with known-good cookware means module replacement ($560–$820). We carry on the truck.
My CT burner lights but the flame is orange
Incomplete combustion. Clogged gas port most common, 0.6mm needle cleanup. If cleaning doesn't fix it, air shutter drift or wrong inlet pressure. Wolf CT wants 5–6" WC natural gas, 10" WC LP. We verify with a manometer, swap regulator if off ($220–$290).
Freedom Induction zones shut off during Boost
Thermal protection cutting power because inverter boards overheating. Cooling fan intake is clogged, cleaning vents resolves 60% of these calls. If cleaning doesn't hold, fan motor $240–$340, or end-of-life inverter $720–$1,050 per board.
Can you replace a cracked glass on my Freedom Induction?
Yes, but it's expensive, the glass has the 56-coil sensor grid bonded underneath, so you replace the whole assembly together. Part $780–$1,150, labor 2 hours. Cooktop comes out, new assembly installs, sensor calibrates on reinstall. Not DIY, frame gaskets have to seat correctly or liquid gets into the inverter compartment below.
How much does Wolf cooktop repair cost?
Diagnostic $89, waived with repair. Common jobs: spark module $285–$425, surface igniter $185–$275, ICBCT inverter $720–$1,050, sensor grid $560–$820. See the pricing table on this page for the full list.
How fast can you come out?
Same-day on calls before 1 PM weekday inside regular coverage. Malibu, Hidden Hills, Pacific Palisades get next-morning priority. For a dead cooktop before a dinner party, call and say so, we rearrange routing.
