Wolf Range Clicking Non-Stop in Forest Hill

The call

Forest Hill, a Wolf GR366 professional range. Two of the six burners lit normally and then kept clicking — the spark continuing indefinitely while the flame burned steadily beside it. The owner had turned those burners off at the wall and stopped using them, which was a sensible instinct.

Their question when they called was whether they needed a gas technician. It is a fair assumption, because everything about the symptom feels gas-related, and we get asked it regularly.

The answer is no, and it is worth explaining why: the clicking is an electrical fault. The spark module has not been told the burner lit, so it keeps trying. The gas side is doing exactly what it should.

Diagnosis

On these ranges the ignition system runs a spark until it receives confirmation of flame. If that confirmation never arrives — even though the flame is plainly there — the module keeps firing.

Three things commonly break that feedback loop, and we worked through all of them:

• Igniter electrodes — cracked ceramic or carbon buildup, so the spark grounds in the wrong place. Both affected igniters were sooty but intact
• Burner caps seated incorrectly — a cap sitting slightly proud changes the flame geometry and the sensing path. Both were correctly seated
• Spark module — the component that generates and monitors ignition

The module was the culprit. Testing showed it firing continuously on the two affected channels regardless of flame state, while the other four channels behaved normally. A module can fail partially like that, which is why some burners were fine.

We also cleaned the igniters and their surrounds regardless, because carbon buildup would have degraded the new module’s performance eventually.

The fix

Spark module replaced with the Wolf factory part. This is not a place for a generic component: aftermarket ignition modules on these ranges are the single most common cause of the never-stops-clicking complaint we get called back to, because the part energises correctly but the timing and sensing thresholds are wrong.

Igniters cleaned, caps checked and reseated, and every one of the six burners tested through a full light-and-settle cycle. Eighty minutes on site.

Outcome

All six burners now light and stop sparking as they should.

I had convinced myself this was a gas leak of some kind. Knowing it was the electronics was a relief before you even fixed it.

The boundary matters here, and we state it the same way every time: we handle the electrical side of gas ranges — spark modules, igniters, switches, control boards, sensors, convection systems and calibration. Gas line and burner work belongs to a separately licensed trade, and we will tell you plainly when a job needs one rather than improvising on an appliance like this.

If your range clicks after the burner has lit, it is not dangerous in itself, but it is worth fixing: continuous sparking wears the igniters and the module, and it will not resolve on its own.
