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 diagnose 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. Turn the burner off, let the cooktop dry completely, and try again. That clears it most of the time.
Next most common is a misaligned burner cap or food debris around the electrode. A cap that’s sitting crooked changes the spark gap. You can check that the cap sits flat and centered and press it back into place. If it clicks with a dry, clean cooktop and the cap properly seated, the spark switch behind that knob or the spark module itself is failing. That’s a part replacement.
Why it won’t light at all
A few things can be happening:
-
Wet or dirty electrode. Same moisture story. Let the cooktop dry fully and retry.
-
Clogged burner ports. The small holes around the burner ring carry the gas. Grease and spillover plug them over time. When a tech services the burner, clearing these ports is part of the job.
-
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 squarely.
-
No gas to that burner. If every burner is dead, verify the supply valve behind the range is open and that the range is plugged in. The spark module runs on house power even on a gas stove.
A useful shortcut: if the other burners light fine, your gas supply and spark module are both good, so the fault is local to the one dead burner. That narrows it to a clog, a cracked igniter, a wet electrode, or the cap.

When to call a pro
Drying the cooktop and reseating the cap are safe first steps. Stop there and call us 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 and call PG&E before anything else.
-
The ceramic igniter is cracked, the spark module is failing, or the burner ports need clearing. All of that involves working around the gas orifice and house power.
A wrong reassembly near the gas line costs more to fix than the original repair. We diagnose it, source the correct OEM part for your model, and send a written estimate before any wrench work. No surprise bills.

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. Let the cooktop dry, check that the cap is seated squarely. If it persists on a dry, clean surface, the spark module or switch is failing and needs replacement.
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 releasing 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. A tech can pinpoint and fix it in one visit.
Can I replace the igniter myself? Drying and reseating the cap is fine homeowner work. Replacing a spark module or igniter means working near the gas orifice and disconnecting house power. A wrong reassembly can cause a gas leak. Have a licensed tech handle it.
