Your Wolf gas cooktop (model CG365P/S) clicks when you turn the knob, but the burner will not catch, or one burner has gone quiet with no spark at all. On a professional cooktop with spark ignition and automatic reignition, this is one of the more common calls, and the cause is usually a short list of simple issues or a single failed part.
There are two versions of this problem, and telling them apart saves time:
Clicks but will not light. You hear the igniter sparking, but the flame never establishes. The spark means the cooktop has power, so this usually points to burner caps, a wet or dirty burner, air in the gas line, or gas delivery.
No click and no spark on one burner. That burner does nothing while others work, or the whole cooktop is dead. This points to power, a spark switch, the igniter, or wiring.
Work through the checks below in order. The first several are safe to do yourself. Anything involving the igniter, spark module, gas valve, or wiring is best left to a technician, both for safety and because gas work carries real risk.
Start Here: Clean, Dry, Seated, and Powered
Dry the burner. If the burner is wet from a spill or recent cleaning, it will click but not light. Let it dry fully. A hairdryer on a low setting speeds this up.
Clean the burner and clear the ports. Grease and food debris around the burner ports block gas from reaching the flame. Once the burner is cool, clean the cap and ring so the ports are clear.
Seat the caps and rings correctly. Burners light only when the cap and ring are properly positioned. After cleaning, make sure each one is seated flat and aligned. A cap sitting slightly off is a frequent reason a clean burner still will not catch.
Confirm the cooktop has power. Even though it burns gas, Wolf needs electricity for the igniter to spark. If burners are sparking, you have power. If there is no spark and no LED activity, check the home breaker, confirm the unit is plugged into a working outlet, and avoid extension cords, which cannot reliably carry the voltage.
Clear air from the gas lines. If the cooktop, or that burner, has not been used in a while, extra clicking is normal as air works out of the line. Turn the burner off after about 10 seconds if it has not lit, wait a minute, and try again.
Check the pan. A pan that is too large for the burner can starve it of air and interfere with ignition. Move an oversized pot off while you test.
Reset the cooktop. Switch the home breaker for the cooktop off for 30 seconds, then back on, and test again.
If the burner still will not light, or clicks constantly, the cause is likely a component.
Common Component Causes (Professional Territory)
These involve the ignition system, gas valve, or wiring, and are best handled by a technician experienced with Wolf.
Spark igniter or electrode. The igniter must build enough charge to spark and light the gas. A cracked, worn, or fouled electrode sparks weakly or in the wrong spot, so the burner will not catch. This is one of the most common failures.
Spark switch. If a burner does not click at all when you turn the knob while others do, the spark switch behind that knob is a likely cause and needs replacing.
Gas valve. If a burner sparks correctly but no gas arrives, the burner’s gas valve may be at fault, so gas is reaching the igniter but not the flame.
Wiring and polarity. Constant clicking, or a burner that sparks even when off, can come from a wiring or outlet polarity problem. This is a diagnosis for a technician or, for house wiring, an electrician.
Flame sensor and reignition system. The CG365P/S automatically reignites a burner if the flame blows out. A fault in that sensing and reignition circuit can cause a burner to click repeatedly or drop out mid-cook.
Common Mistakes to Avoid
Assuming it is always the igniter. A wet burner, a misaligned cap, clogged ports, or air in the line stop ignition just as often, and cost nothing to fix.
Reassembling caps in the wrong spot. If the cap and ring are not seated correctly, even a perfect igniter will not light the burner.
Ignoring constant clicking. A burner that clicks nonstop, or sparks when off, points to moisture, wiring, or the ignition circuit and should be diagnosed, not left running.
Using extension cords. They can cause voltage drops that interrupt the igniter. Plug the cooktop into a proper outlet.
Working on the gas valve or wiring yourself. Gas and electrical work on a cooktop carries real risk and is best left to a professional.
When to Call Flamingo
Bring in a professional when:
You have cleaned and dried the burner, seated the caps, confirmed power, cleared the lines, and it still will not light.
A burner does not spark at all, clicks constantly, or sparks when off.
The cooktop needs an igniter, spark switch, gas valve, flame sensor, or wiring work.
Flamingo Appliance Service has repaired high-end kitchen appliances across South Florida and Georgia for over 30 years, including Wolf, Sub-Zero, and Cove. Our team of 120-plus technicians runs about 15,000 service calls a month, completes over 100 hours of training a year, and uses parts sourced only from the manufacturer or authorized distributors, backed by a one-year parts warranty.
One honest note on warranty: Wolf backs the CG365P/S with a two-year manufacturer warranty from the date of installation. Flamingo is an independent service company and is not a Wolf factory-authorized provider, so if your cooktop is still inside that window, confirm your coverage first, since work by a non-authorized shop can affect it. Once you are out of warranty, we are an experienced, well-stocked choice to get your burners lighting again.

Quick Checklist Before You Call
Burner fully dry after any spill or cleaning?
Cap and ring cleaned, ports clear, and seated correctly?
Cooktop has power, no extension cord, breaker on?
Burner turned off 10 seconds and retried to clear air from the line?
Oversized pan moved off during testing?
If all of those check out and the burner still will not light, the ignition or gas system needs a professional.
Frequently Asked Questions
Why does my Wolf burner click but not light? Usually a wet or dirty burner, a cap that is not seated correctly, or air in the gas line. Dry the burner, clean and reseat the cap and ring, then turn the burner off for a few seconds and try again. If it still will not catch, the igniter or gas valve may need service.
One burner does not click at all. What is wrong? If that burner makes no spark while others do, the spark switch behind its knob is a common cause and needs replacing. Confirm the cooktop has power first.
Why does my cooktop keep clicking even after the burner lights, or when it is off? Constant clicking often means moisture, a misaligned cap, or a wiring or polarity issue. Dry and reseat the burner first. If it continues, or sparks when off, have it diagnosed.
Does a gas cooktop need electricity? Yes. Wolf uses an electric spark to light the gas and to automatically reignite a burner if the flame goes out. No power means no spark, so check the breaker and outlet.
Can I fix this myself? You can safely clean and dry the burner, seat the caps and rings, check power, and clear air from the lines. The igniter, spark switch, gas valve, and wiring involve gas and electrical work and are best left to a technician.
