A clicking gas stove is one of the most common cooktop calls we get. Sometimes the burner lights and the clicking just will not quit. Other times the spark fires and fires and nothing catches. Both point back to the spark ignition system, and most of the causes are things you can read before anyone touches a tool. This plays out the same on a GE, Samsung, Whirlpool, or Frigidaire, since they all use the same knob-switch-to-spark-module chain.
Here is how it works in plain terms. Turn the knob, a switch tells the spark module to fire an electrode next to the burner, the spark jumps and lights the gas, and the clicking stops within a second or two. When it keeps going or the gas never catches, something in that chain is off.
Why it clicks after it lights
The usual culprit is moisture. A boilover, a wiped-down cooktop, steam off a tall pot. Water bridges the gap around the electrode and the module keeps sparking even with the flame already burning. Turn the burner off, let the cooktop dry completely, and retry. That clears it most of the time.
Next most common is a crooked cap or food debris around the electrode. A cap sitting off changes the spark gap. Check that it sits flat and centered and press it back into place. If it still clicks with a dry, clean cooktop and the cap seated right, the switch behind that knob or the module itself is failing. That is a part replacement.
Why it won’t light at all
A few things can be happening:
- Wet or dirty electrode. Same moisture story. Let it dry fully and retry.
- Clogged ports. The small holes around the burner ring carry the gas, and grease and spillover plug them over time. Clearing them is part of a burner service.
- Cracked ceramic igniter. The electrode sits in a small white porcelain base. Chipped or cracked, the spark grounds out instead of jumping to the burner, and you often see no spark on that one burner. Needs a new igniter.
- Cap seated wrong. Off by a few millimeters can stop ignition entirely. Reseat it squarely.
- No gas to that burner. If every burner is dead, check that the supply valve behind the range is open and the range is plugged in. The module runs on house power even on a gas stove.
Quick shortcut: if the other burners light fine, gas and the module are both good, so the fault is local to the 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 module is failing, or the ports need clearing. All of that means 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 give you a written repair-or-replace call and price after the $75 diagnostic. No surprise bills.

FAQ
Why does it keep clicking after it lights? Usually moisture or debris bridging the electrode, or an off-center cap. Let it dry and check the cap. If it persists on a dry, clean surface, the module or switch is failing.
Is it safe to keep using? If the burner lights with a steady blue flame, briefly yes. If it clicks without lighting, it is releasing raw gas. Shut it off and ventilate.
Why won’t one burner light when the rest do? The fault is local to that burner: a clogged port, cracked igniter, wet electrode, or crooked cap.
Can I replace the igniter myself? Drying and reseating the cap is fine. Replacing a module or igniter means working near the gas orifice and cutting house power, where a wrong reassembly can leak gas. Have a licensed tech handle it.
