Wolf cooktop & rangetop repair.
A rangetop stands on a platform in the run of cabinets; a cooktop drops into a cutout in the counter. Sealed gas burners or electric elements under glass, we look after both.
What We Service
Aphelion Appliance Repair, an independent company, repairs Wolf rangetops and Wolf gas and electric cooktops across the Phoenix metro, including Scottsdale and Paradise Valley. The diagnostic visit is $119, waived when you go ahead with the repair, and repairs made with the genuine parts we supply carry 12 months on parts and labor.
Sealed burner rangetops
The SRT in 30, 36 and 48 inches: surface burners, and the charbroiler, griddle, French top or wok burner set beside them.
Gas cooktops
CG and the earlier CT, 15 to 36 inches: burners, caps, knobs and the gas valves under them.
Electric cooktops
CE and CT glass-ceramic cooktops: heating elements, touch controls, and the lock that passes for a failure.
Ignition
A spark that never comes, or never stops: igniters, switches and the spark module. What we do on ranges and ovens.
Inside a Wolf Rangetop and Cooktop
One burner, two tiers of flame.
Wolf’s name for it is a dual-stacked, sealed burner. Its documents put it on the sealed burner rangetops and on the CG gas cooktops, and a comparison Wolf publishes gives the earlier CT cooktops the same burners, with automatic re-ignition on all settings. The flame stays in the upper tier from high down to low. Turn the knob to the detent at the lowest setting, push, keep turning, and it moves to the second tier, where simmer is. On a current rangetop the ratings go by position: 20,000 Btu at front left and 18,000 for any burner to its right, 9,200 at rear left and 15,000 to the right of that; rangetops before serial number 18180000 carry lower totals in Wolf’s table. A CG cooktop mixes burners of 18,000, 12,000 and 9,200 Btu, with one of 20,000 on the 36-inch Contemporary.
Lighting is electric. Push a knob in and turn it to Hi, and the igniter clicks until the burner lights, in about three to four seconds by Wolf’s answer; propane can take longer at the first light of the day. Once the flame is there, the control watches the electrical resistance between the electrode and the burner, and any change in it, up or down, makes the electrode spark again. That is how a flame that has gone out is relit, and it is why a wet burner, a cap off-center or a pan big enough to starve the flame of air can set off clicking with nothing broken. So a gas Wolf still needs power, a 120-volt, 15-amp circuit of its own, and the Design Guide adds that a GFCI on a gas cooktop’s circuit is not recommended and may interrupt operation.
Beside the burners a rangetop may carry sections with a burner and an igniter of their own. The infrared charbroiler, rated 16,000 Btu on the 36-inch SRT364C, runs at Hi, wants ten minutes of preheat, and should light within 20 seconds. The infrared griddle is the thermostatic one: its knob is marked from 100°F to 450°F, a light above the knob stays on until the plate reaches the set temperature and then cycles, and a double griddle has a control for each side. The French top is a graduated plate with its burner under the center, hottest there, and Wolf asks for 30 minutes of preheat. A wok burner takes a wok of 14 to 18 inches.
An electric Wolf cooktop is a glass-ceramic surface over heating elements, single, dual-zone, triple-zone and bridge, worked from touch controls that are invisible while the cooktop is off. The elements pulse instead of dimming: Wolf describes high-frequency pulsation between zero power and full power, the full-power periods growing longer as the setting rises. The largest element on a 30- or 36-inch cooktop is a triple at 1,050, 1,950 and 2,700 watts, and the bridged pair on a 36-inch is rated 4,400. Wolf’s own model timeline ends the electric line in 2025. Range and oven parts in plain words.

- SimmerSecond tier, past the detent
- LightingElectric, 3 to 4 seconds
- Griddle100–450°F, thermostatic
- ElectricElements pulse, up to 4,400 W

In a power outage Wolf allows the surface burners to be lit by hand, a wok burner excepted, warns that there is then no automatic re-ignition, and says not to try it with a griddle, a charbroiler or a French top. One visit can take in the Wolf wall oven under the cooktop as well: $119 for the first appliance and $69 for each additional one, each fee waived when its repair goes ahead.
Common Symptoms
Six faults of a Wolf rangetop or cooktop, each set against Wolf’s own answer. A row opens the request form with the symptom already entered. If it is the color of the flame that has changed, read yellow flames on a gas range first.
- 01Burner clicks but will not lightWolf starts with a wet or dirty igniter, a cap out of place and food in the burner holes; a burner left unused may need a second try while air clears from the line.igniter · burner cap
- 02Clicking that will not stopWith the flame lit: moisture, a pan too large for the burner, or a knob that has not sprung back. Constant sparking sends Wolf to the outlet’s wiring and polarity, then to the spark parts.switch · electrode · spark module
- 03Flame uneven, or simmer will not holdWolf’s guides file it under erratic flame: caps positioned properly, the burner and igniter clean, everything dry after a spill, and a cap that fastens to the burner head fastened tight.caps · burner holes
- 04Griddle will not heat, or its light flashesA flashing light means the flame was lost and the griddle went into safety lock-out: knob off, then on. No heat after that, and Wolf names the spark module, switch, igniter, gas supply or thermostat.igniter · thermostat
- 05Charbroiler clicks, or will not lightThe knob has to be fully at Hi. Then a wet or dirty igniter, a clogged infrared burner, or a charbroiler that is not properly assembled; Wolf expects it to light within 20 seconds.igniter · infrared burner
- 06Electric cooktop will not turn on, or one element is outLock mode comes first: by default the panel locks itself after ten idle minutes, and it starts locked after a power outage. Then the breaker, off for 30 seconds; past that Wolf calls for service.lock mode · elements
If you smell gas.
Do not switch anything on or off, and do not use a phone inside the house. Leave, and call Southwest Gas, or your propane supplier, or 911 from outside.
A gas smell is an emergency for the utility, not a repair appointment. We come once it is safe. We repair the appliance itself; new gas lines and supply connections are work for a licensed gas contractor, and we will tell you plainly when a job has reached that line.
Wolf’s Own Lists, Section by Section
Taken from the sealed burner rangetop guide, the gas cooktop guide, the electric cooktop pages and Wolf’s support answers. The middle column belongs to the owner; the last is where Wolf stops giving advice.
| What it does | Wolf’s checks | Then |
|---|---|---|
| Rangetop does not operate | Power on; the home circuit breaker; the supply off for 30 seconds and on again | Wolf Factory Certified Service. The guide adds that Wolf is not responsible for service needed to correct a faulty installation |
| Erratic flame, poor ignition or none | Burner caps positioned properly; the burner and igniter cleaned; after a spill, the area dried completely, with a hair dryer if desired; a cap that fastens to the burner head tightened; the knob pushed in and let go, to see it spring back | No further step, in the rangetop guide and the gas cooktop guide alike |
| Clicking with the flame lit, or with the burner off | The burner dried; a large pan turned down to low; the knob pushed in and released; rings and caps centered and flat; the breaker off for 30 seconds | The spark module, switch, electrode or igniter. Sparking with nothing in use is an electrician’s question first: the outlet’s wiring and polarity |
| Charbroiler clicks continually, or will not light | The knob fully at Hi; the igniter dried and brushed clean; the ports of the infrared burner cleared with a toothpick or an unfolded paper clip; the charbroiler properly assembled; ten minutes of preheat; power reset at the breaker | Service, if it does not light within 20 seconds after all that |
| Griddle light flashes | The knob off, then on: the flame was lost and the griddle entered safety lock-out | — |
| Griddle will not light or heat | The knob in the right position and not stuck: taken off, refitted, pushed in and released; the supply reset at the breaker | Wolf has no further advice: service, for the spark module, switch, electrode or igniter, gas supply or thermostat |
| Burner pan uneven | The rangetop on a level platform and pushed all the way back; the grate sitting level on the pan | Wolf Factory Certified Service |
| Electric cooktop does not operate | Power and the breaker; lock mode, cleared by holding Lock for three seconds. It also turns itself off after 2 hours on high, 6 on medium and 8 on simmer, except in Sabbath Mode | — |
| Electric element will not heat, or heats poorly | Not locked; power reaching the unit; the breaker off for 30 seconds; the power switched on and off at least three times | Service, in Wolf’s answer |
Wolf’s fuller list for a burner that will not light, set beside Viking’s, is in a burner that clicks and will not light. Cleaning caps, grates and igniters without wetting the ignition, with dated retail prices for Wolf’s spark modules: range care.
Wolf’s lists hand what is left to Wolf Factory Certified Service, and inside Wolf’s warranty so do we. We are an independent company; our work is the appliance, from its own gas inlet inward, once the maker’s coverage has ended.
Which Wolf rangetop or cooktop do you have?
The table sets out two generations of rangetop and two of each kind of cooktop. The letters at the front of the model number say which one is in the kitchen. Where each Wolf tag sits.
| Family | Model numbers | Made | How to tell | Rating plate |
|---|---|---|---|---|
| Sealed burner rangetop | SRT304; SRT366, SRT364C, SRT364G, SRT362W; SRT486C, SRT486G, SRT484CG, SRT484DG, SRT484F, SRT484W | 2006 to date; the wok models SRT362W and SRT484W appear in Wolf’s tables only from serial number 18180000 | Dual-stacked sealed burners over a burner pan that does not lift out | Bottom of the control panel, far right |
| RT Series rangetop | RT366, RT364C, RT364G; RT488, RT486C, RT486G, RT484CG, RT484DG, RT484F | 2002 to 2011 | Open burners; the burner pans lift out with a hook | Under the left surface burner pan, on the left side wall |
| CG gas cooktop | CG152TF/S; CG243TF/S; CG304T/S, CG304P/S; CG365T/S, CG365P/S, CG365C/S | 2015 to date; the 15-inch CG152TF/S from 2017 and the Contemporary from 2016; CG243TF/S is in Wolf’s 2025 Design Guide but not on its timeline | Transitional, Professional or Contemporary; one burner of 18,000 Btu, or 20,000 on the Contemporary | Bottom of the cooktop |
| CT gas cooktop | CT15G/S, CT30G/S, CT36G/S | 2002 to 2014; the 15-inch to 2016 | The style Wolf calls traditional; no burner above 15,000 Btu | Bottom of the cooktop |
| CE electric cooktop | CE152T/S, CE304T/S, CE365T/S, CE304C/B, CE365C/B | 2015 to 2025 | Touch controls, invisible when off, with a Lock key and an All Off key | Bottom of the cooktop |
| CT electric cooktop | CT15E/S, CT30E, CT36E | 2002 to 2015 | The electric line before the CE | Bottom of the cooktop |
Wolf’s model number key reads the rest. SRT is a sealed burner rangetop, CG a gas cooktop and CE an electric one. The Design Guide sorts rangetops by width, so SRT36 is 36 inches, and the letters after the digits are the sections: C a charbroiler, G a griddle, DG a double griddle, F a French top, with SRT362W shown as the wok model. On a cooktop, T, P and C are Transitional, Professional and Contemporary. -LP at the end is propane. Wolf, Viking and Monogram ranges compared.
Wolf’s warranty, part by part.
The same Wolf Appliance Residential Limited Warranty closes the rangetop guide, the gas cooktop guide and the electric cooktop guide. All parts and labor for two years, counted from the date of original installation and carried out by Wolf Factory Certified Service; three years if a Factory Certified Installation company fitted the appliance. While that runs, the repair is Wolf’s to make and the number is 800-222-7820. We are an independent company and would send you there ourselves.
After that comes a five-year list, printed the same in all three guides. Among the parts it names are the gas burners, appearance excluded, the electric heating elements and the electronic control boards. An igniter, a valve or a griddle thermostat is not named in it, and whether a spark module counts as a control board is Wolf’s to say. For a listed part, an owner using any service but Wolf’s has to ask Wolf for the part before one is bought, since Wolf will not reimburse a part from another source, and the labor is the owner’s.
Two exclusions matter on gas. The warranty does not cover a defect caused by improper installation, and the rangetop guide says outright that Wolf is not responsible for service required to correct a faulty one. A supply outside the pressures in Wolf’s Design Guide, 7 to 14 inches of water column for natural gas and 11 to 14 for propane ahead of the appliance’s own regulator, is an installation matter, and it belongs to a licensed gas contractor. How the four makers’ warranties compare.
The rest of a Wolf kitchen: Wolf ranges, and the maker as a whole, and Wolf wall ovens.
Wolf cooktop and rangetop questions
Do you repair Wolf rangetops and cooktops, gas and electric?
Yes: sealed burner rangetops with their charbroiler, griddle or French top, CG and CT gas cooktops, and CE and CT electric cooktops. Aphelion Appliance Repair is an independent company working across the Phoenix metro, Scottsdale and Paradise Valley included. The diagnostic visit is $119, waived when you go ahead with the repair. We repair the appliance itself; gas lines and new connections are a licensed gas contractor’s work.
The igniter on my Wolf rangetop or cooktop clicks but the burner will not light. What should I try?
Wolf’s steps: make sure the burner is clean and dry, brush the igniter gently with a soft dry toothbrush, clear food from the burner holes with a toothpick, and seat the cap properly. If it has not lit after 10 seconds, turn it off and wait a minute before trying again. Then switch the home circuit breaker off for 30 seconds. If it still will not light, Wolf sends it to service. If you smell gas, leave the house and call Southwest Gas or 911 from outside.
The light above the griddle knob on my Wolf rangetop is flashing. What does it mean?
Wolf’s guide gives one cause: the flame was lost and the griddle entered a safety lock-out. Turn the knob off, then back on. In normal use the same light stays on until the griddle reaches the set temperature, then cycles on and off as it holds it. A griddle that still will not heat is a repair; Wolf names the spark module, the switch, the igniter, the gas supply and the thermostat.
My Wolf electric cooktop will not turn on. Is it broken?
It may only be locked. Wolf’s electric cooktops, by default, lock the control panel after ten minutes of inactivity and start in lock mode after a power outage; touching and holding Lock for three seconds releases it. They also switch themselves off after 2 hours on high, 6 on medium and 8 on simmer. If it is unlocked and still dead, Wolf’s next step is the home circuit breaker off for 30 seconds, and then service.
Are the burners on a Wolf rangetop covered for five years?
As parts, yes. Wolf’s limited five-year warranty names gas burners, excluding their appearance, along with electric heating elements and electronic control boards, counted from the date of original installation. The first two years, three with Factory Certified Installation, cover all parts and labor through Wolf Factory Certified Service. After that the owner asks Wolf for the listed part and pays the labor; Wolf does not reimburse a part bought elsewhere.
