Direct answer: A gas cooktop that keeps clicking usually has moisture around a burner, a burner cap sitting crooked, food debris in the igniter area, or a burner knob/switch that is still telling the spark module to fire.
Most likely: Start with the burner that was just used or cleaned. Wet burner parts and slightly off-center caps are the most common reasons a cooktop keeps sparking and clicking.
First figure out whether the clicking happens only at one burner, after cleaning, or all the time even with every knob off. That split matters. Reality check: a little clicking while a burner lights is normal. Common wrong move: scrubbing the igniter hard or flooding the burner with cleaner, which often makes the problem worse.
Don’t start with: Don’t start by ordering a spark module. Most nonstop clicking complaints turn out to be moisture, spill residue, or a knob/switch issue at one burner.
The ticking is centered at one burner, especially after cooking over a spill or after wiping the top.
Start here: Check that burner cap alignment is correct and the burner base and igniter area are fully dry and free of food crust.
You hear rapid ticking from multiple burners even though you are only using one, or with every knob off.
Start here: Look for a wet or stuck burner knob first, then suspect a cooktop ignition switch sending a constant spark signal.
The cooktop worked before, then began clicking after spray cleaner, a wet rag, or heavy scrubbing.
Start here: Remove burner caps and let the burner parts air-dry fully. Moisture around the igniter is the first thing to rule out.
The burner lights, but the spark keeps snapping for a few seconds or keeps going until you turn the knob back.
Start here: Clean and dry the burner head and igniter area, then check whether the burner cap is seated flat and the flame is crossing evenly.
This is the most common cause after cleaning, boil-overs, or steam-heavy cooking. A damp igniter path can keep the spark jumping.
Quick check: Remove the grate and burner cap from the noisy burner and look for water beads, dampness, or a recent spill trail.
If the cap sits crooked, gas flow and flame crossover get uneven, so the igniter keeps trying to light what it thinks is a weak flame.
Quick check: Lift the cap and set it back so it sits flat with no rocking. Compare it to a burner that works normally.
Grease, sauce, and carbon buildup can redirect the spark or delay ignition, which sounds like nonstop clicking.
Quick check: Look for crusted residue around the white igniter tip, burner ports, and the notch where the flame should travel.
If the clicking continues with all knobs off, or starts when you touch one knob and does not stop, the switch side becomes much more likely.
Quick check: Turn each knob slowly from off to lite and back. A mushy, sticky, or slow-return knob is a strong clue.
You want to separate a wet or dirty burner from a switch problem before taking anything apart.
Next move: If one burner clearly stands out, stay with that burner first. That usually means moisture, misalignment, or debris rather than an electrical part failure. If all burners click together or the clicking continues no matter which burner you touch, move quickly to the knob and ignition switch checks.
What to conclude: A single noisy burner usually points to a local burner issue. Whole-cooktop clicking with knobs off points more toward a stuck switch signal.
Moisture is the easiest fix and the most common cause, especially after cleaning.
Next move: If the clicking stops after drying, the problem was moisture and no parts are needed. If the clicking returns right away, go on to cap alignment and debris checks.
What to conclude: A temporary fix after drying strongly supports a moisture path, not a failed spark module.
A cap that is slightly off and a dirty igniter tip can keep the burner sparking even when flame is present.
Next move: If the burner lights promptly and the clicking stops within normal ignition, the issue was alignment or residue. If that burner still clicks after it lights, or lights unevenly around the ring, the burner or igniter area may be damaged or still contaminated.
When the cooktop keeps clicking with all knobs off, the switch side becomes the main suspect.
Next move: If cleaning and reseating a knob stops the random clicking, the switch area was likely sticky from grease or moisture. If the clicking continues with all knobs off and no burner-specific issue stands out, a cooktop ignition switch is the most likely failed part.
By now you should know whether this is a simple burner issue or a deeper ignition control problem.
A good result: If each burner lights cleanly and the clicking stops right away, the repair path was correct.
If not: If the cooktop still clicks unpredictably after drying, cleaning, reseating, and switch checks, the safest next move is appliance service because diagnosis has moved past simple homeowner checks.
What to conclude: Single-burner problems usually stay at the burner. Whole-cooktop clicking with knobs off usually lands on the ignition switch side.

Usually because moisture got around the burner head, igniter, or knob area. Let the parts dry fully, then reseat the burner cap and test again.
On many gas cooktops, yes. It is common for the ignition system to spark at multiple burners while you are lighting one. It is not normal if the clicking continues after the burner is lit or with all knobs off.
Yes. If the cooktop burner cap is crooked, warped, or not seated flat, the flame may not spread correctly and the igniter can keep firing.
That usually means the flame is not crossing cleanly where it should, or the igniter area is dirty or damp. Start with cleaning, drying, and cap alignment before suspecting parts.
Replace it only after you have ruled out wet burners, dirty igniter areas, and sticky knobs. If the cooktop keeps clicking with every knob off, the cooktop ignition switch becomes a strong suspect.
Not if you smell gas, get delayed ignition, or see flames behaving oddly. If it is only a brief post-cleaning moisture issue and the burners light normally, drying and cleaning may solve it. If not, stop and service it.
