Wolf range or cooktop keeps clicking: what it means and what fixes it

Why a Wolf burner clicks while it’s lit

When you turn a Wolf burner on, the electrode sparks until the gas lights. If the system thinks the flame has gone out, it sparks again to relight it. A burner that keeps clicking while it’s visibly burning means the system isn’t recognizing the flame, so it keeps trying to relight a burner that’s already lit.

Checks you can do yourself

1. Let it dry. If the clicking started after a boil-over or after cleaning the cooktop, moisture around the burner or electrode is the most common cause. Leave the burner off and let it dry completely, then try again.
2. Re-seat the burner cap. With the cooktop cool, lift the cap off and set it back so it sits flat and centered. A cap that’s slightly off changes the flame and can keep the burner clicking.
3. Clean the burner. Food and grease in the burner ports give an uneven flame. Clear the ports gently with a straightened paper clip, not a toothpick.
4. Check which burners click. One burner points to that burner’s parts. All of them clicking at once, especially with the knobs off, points to the ignition electronics or moisture in a switch, and needs a technician.

If you smell gas strongly, or the smell doesn’t go away, turn the appliance off, don’t operate light switches, leave the house and call your gas utility from outside.

What we found on real Wolf repairs

Corroded burners that couldn’t be rebuilt

On a Wolf CG304P/S gas cooktop in Redmond, set in a kitchen island with a pop-up downdraft vent, two of the four burners lit but kept clicking the entire time they were on. We pulled both: the burner bases were heavily corroded underneath, and the end of one igniter lead was corroded through. On that model the burner can’t be taken apart and rebuilt, so cleaning wasn’t a real fix. We replaced both burners with new assemblies, each with its own electrode and lead, then lit every burner. Each one lit, stayed lit, and stopped clicking. The other two burners were working normally and were left alone.

No spark at all: the spark modules

The opposite symptom has a different cause. On a Wolf GR486G 48-inch range in Kirkland, the four burners on the right side had stopped sparking, so they couldn’t be lit. The spark modules, the parts that generate the spark, had failed. We replaced both with genuine Wolf parts and, with the cooktop already open, cleaned and serviced every burner.

When to call

• The clicking continues after the burner has dried out and the cap is seated properly.
• Burners click with the knobs off.
• Several burners stop sparking at once.
• You can see rust or corrosion around a burner base.

Constant clicking can come from moisture, a dirty burner, a switch, the spark module, or the burner itself, so we look before we replace. If you have a BlueStar or another brand, our burner troubleshooting guide covers the same symptoms more generally.
