A clicking gas stove is one of the most common cooktop calls we get. Sometimes the burner lights anyway and the clicking just won’t quit. Other times the spark fires and fires but nothing catches. Both point back to the spark ignition system, and most of the causes are things you can check before anyone touches a tool.
Here’s how the system works in plain terms. When you turn the knob, a switch tells the spark module to fire a small electrode next to the burner. That spark jumps to the burner, ignites the gas, and the clicking should stop within a second or two. When the clicking keeps going or the gas never lights, something in that chain is off.
Why it keeps clicking after it lights
The usual culprit is moisture. Boil-over, a wiped-down cooktop, steam from a tall pot. Water bridges the gap around the electrode and the module keeps trying to spark even though the flame is already burning. The fix is simple: turn the burner off, let the cooktop dry completely, and try again. A few minutes of air, or a careful pass with a hair dryer on low, usually settles it.
Next most common is food debris or a misaligned burner cap. Crumbs and carbonized grease around the igniter throw off the spark. A cap that’s sitting crooked changes the gap. Lift the cap and the burner ring, brush out the ports, and set the cap back down so it sits flat and centered. You should feel it drop into place.
If the cooktop is bone dry and clean and a single burner still clicks nonstop, the spark switch behind that knob or the spark module itself is failing. That’s a part replacement, not a cleaning.
Why it won’t light at all
Run through these in order:
-
Wet or dirty electrode. Same moisture and debris story above. Dry it out, clean it, retry.
-
Clogged burner ports. The little holes around the burner ring carry the gas. Grease and spillover plug them. Clear each port with a straightened paperclip or a needle, never something that breaks off inside.
-
Cracked ceramic igniter. The electrode sits in a small white porcelain base. If it’s chipped or cracked, the spark grounds out instead of jumping to the burner. You’ll often see no spark at all on that one burner. This needs a new igniter.
-
Cap seated wrong. A cap that’s off by a few millimeters can stop ignition entirely. Reseat it.
-
No gas to that burner. If every burner is dead, check that the supply valve is open and, on a slide-in range, that it’s plugged in. The spark module runs on house power even though the stove is gas.
A useful shortcut: if the other burners light fine, your gas supply and spark module are good, so the problem is local to the dead burner. That narrows it to a clog, a cracked igniter, a wet electrode, or a cap.
When to stop and call a pro
Do the cleaning, drying, and cap reseat yourself. Stop there if any of these are true:
-
The burner clicks but never lights, and you smell gas. Shut it off and ventilate. Raw gas is releasing.
-
You smell gas with all the knobs off. Leave the house and call PG&E.
-
The igniter ceramic is cracked, or the spark module needs replacing. That work involves house power and the gas orifice.
Replacing a spark module or igniter is a parts-driven job, and a sloppy reassembly around the gas line is exactly the kind of mistake worth avoiding. We diagnose it, look up the OEM part for your model, and send a written estimate before any wrench work.

FAQ
Why does my gas stove keep clicking after it’s lit? Usually moisture or debris bridging the igniter, or an off-center burner cap. Dry the cooktop, clean around the electrode, and reseat the cap. If it persists on a dry, clean surface, the spark module or switch is failing.
Is it safe to keep using it? If the burner lights with a steady blue flame, briefly yes. If it clicks without lighting, it’s leaking raw gas. Shut it off and ventilate.
Why won’t one burner light when the rest work? The fault is local to that burner: a clogged port, cracked igniter, wet electrode, or misaligned cap.
Can I replace the igniter myself? Cleaning and reseating is fine. Replacing the spark module or igniter involves house power and the gas orifice, so have a licensed tech do it.
