It clicks, and will not light.
Refrigeration comes first here, but the ranges and ovens of the same four makers sit in the same kitchens, and they generate a particular kind of call. This is what Wolf and Viking themselves publish about a burner that will not light, about the self-clean cycle, and about the oven that is running hot. A surprising share of it ends before anybody drives out.
A Burner That Clicks But Will Not Light
Both makers publish a list, and the two lists overlap but are not the same. A dash means that maker’s published answer does not raise it.
| Wolf | Viking | |
|---|---|---|
| No power to the unit | Yes: the igniters are electric and will not spark or click without it | Yes: a tripped circuit, a blown fuse, or the cooktop not connected |
| Burner cap or ring seated wrong | Yes: a burner lights only with the ring and cap in place, and a screw-in cap fully fastened | — |
| Food in the burner ports | Yes: cleared with a toothpick; the igniter itself with a soft, dry toothbrush | Yes: clogged burner ports |
| A wet igniter after a spillover or a clean | Yes: let it dry, a hairdryer speeds it up; off after ten seconds if it has not lit, a minute’s wait, then try again | Yes: igniters wet or dirty |
| Air in the gas line | Yes: it can take time to clear the line and deliver gas to the burner | Yes: the supply valve off, or the supply interrupted |
| The electrical supply itself | — | Yes: a supply that is not grounded, or whose polarity is reversed |
| The wrong gas, or air shutters | — | Yes: operated on the wrong type of gas, or air shutters not properly adjusted |
Wolf also gives the reset that costs nothing: cut power to the unit, leave it off for at least thirty seconds, restore it and try again. Most of the column above is cleaning, seating and patience, which is why it is worth twenty minutes before it is worth $119.
The oven that is not actually wrong.
Wolf states an acceptable variation of plus or minus ten degrees from the setpoint. An oven reading eight degrees out is behaving to its own specification, and no adjustment will make it read exactly 350; ovens do not work that way, and a separate oven thermometer sitting on a rack in moving air does not measure what the control measures.
Past that band the offset can be calibrated. Two things about it are worth knowing before anyone touches it: it is not a user setting, and it moves every cooking mode at once. If only the baking seems wrong, an offset applied to fix baking will take convection, roast and broil with it. Wolf also asks that service be told if an offset was set before, because an old one is often part of the problem being described.
And one that looks like a failure and is a setting: a Wolf dual fuel oven that refuses to go above 290 is set to Celsius. 290°C is the top of its range. Switch the temperature unit back to Fahrenheit and the numbers return.
The Hottest Thing Your Kitchen Does
- 01
Up to 750°F
Viking puts the self-clean cycle at up to 750°F, held for three to three and a half hours depending on the model, with about another thirty minutes of cool-down before the door will open.
- 02
Take everything out
Viking’s instruction is to remove the broiler pan, the broiler grid, the oven racks and any other utensils before the cycle starts. Racks left in a self-clean come out discoloured and stiff in their runners.
- 03
Listen for the fan
A fan should be audible during the cycle. Viking says that if it is not, call for service before running self-clean again, the one instruction on this page we would not put off.
- 04
Plan it for a cool morning
That is a Phoenix note rather than a manufacturer’s: three and a half hours at 750°F in an August kitchen is a load on the room, and on the refrigerator standing next to it. What the heat already asks of a built-in.
Where our work starts and stops.
We repair the appliance: igniters and spark modules, gas valves and burner assemblies, oven sensors, controls, door seals and hinges, convection motors and heating elements. Gas supply lines and new connections are a licensed gas contractor’s work, said before we come out rather than after we arrive.
One more boundary worth stating plainly, because the makers’ pages say it and we would rather you heard it here too: Wolf’s answer to a temperature calibration is to send Factory Certified Service. We are an independent company and not factory-authorized. If your range is still inside the manufacturer’s own warranty, that call goes to the maker first and it costs you nothing; we would rather tell you that than take the visit. What we do on ranges and ovens.
Range and Oven Questions
The burner clicks but will not light. Is it broken?
Usually not. Wolf’s own list starts with power: the igniters are electric and will not spark without it; then a burner cap or ring seated wrong, food in the burner ports, and a wet igniter after a spillover or a clean. Viking’s list adds a tripped circuit or blown fuse, a gas supply valve left off, a supply that is not grounded or has its polarity reversed, the wrong gas type, and air shutters out of adjustment. None of those is a failed part.
My oven runs hot or cold. How far off is too far?
Wolf states an acceptable variation of plus or minus 10 degrees from the setpoint, so an oven that reads eight degrees out is inside its own specification. Beyond that the offset can be calibrated, but it is not a user setting: it is adjusted in service, and it shifts every cooking mode at once, not only the one that seemed wrong.
The oven will not go above 290. What is wrong with it?
Nothing. On a Wolf dual fuel range that is the oven set to Celsius rather than Fahrenheit; 290°C is the top of its range. Changing the temperature unit back puts the numbers where you expect them.
Is self-clean safe to run?
It is the hottest thing your kitchen does: Viking puts the cycle at up to 750°F for three to three and a half hours, plus about thirty minutes of cool-down. Viking says to take out the broiler pan, the broiler grid, the oven racks and anything else left inside first, and that a fan should be audible during the cycle; if it is not, call for service before running self-clean again.
Do you work on the gas line itself?
No. We repair the appliance: igniters, valves, controls, sensors, seals and the oven itself. Gas supply lines and new connections are a licensed gas contractor’s work, and we say so before we come rather than after.
