Gas Stove Igniter Keeps Clicking? 6 Causes & How to Fix It (2026)

If your gas stove igniter keeps clicking after the burner is lit — or clicks constantly even when you're not using the stove — the most likely cause is moisture from a boilover or recent cleaning that has soaked into the igniter. Dry it out and clean the burner area, and it will almost always stop. If clicking continues after everything is dry and clean, a faulty igniter switch or spark module needs replacement.

Quick Diagnosis

All burners clicking after a spill: Moisture — dry the stove top thoroughly.
One burner clicking constantly: Food debris or misaligned burner cap.
Clicking but no flame: Clogged burner ports or cracked igniter ceramic.
Clicking with knob in OFF position: Stuck switch contact or faulty spark module.
Clicking after cleaning: Water from cleaning spray — leave it to dry 2–4 hours.

Safety first: Before cleaning around any gas burner igniter, turn all burner knobs to OFF, then unplug the stove from the wall outlet (or switch off the circuit breaker). Gas stove igniters are powered electrically — you want no current while working near them.

Cause 1: Wet or Damp Igniter (Most Common)

The igniter tip needs to stay dry to work properly. When liquid from a boilover or from cleaning sprays gets on the igniter or into the recessed igniter well, the moisture creates a conduction path for the spark — and the igniter fires continuously.

This is by far the most common cause of clicking that starts suddenly. The stove may have been working perfectly, then you cleaned the stovetop or had a pot boil over, and now one or all igniters won't stop clicking.

Fix: Use a hair dryer on low heat to dry the igniter area, or simply leave the stove unused for 2–4 hours with the burners open to air-dry. Do not pour or spray any liquid near the igniter during this time. Once fully dry, test each burner.

Cause 2: Food Debris Under the Burner Cap

Cooking splatters, boilovers, and grease accumulate under the burner cap over time. If a large piece of debris — baked-on sauce, a piece of pasta, a chunk of food — gets lodged between the igniter tip and the burner cap, it can conduct electricity and trigger continuous clicking. Fine grease buildup on the igniter tip itself can do the same thing.

How to Clean the Igniter Safely

Turn all burner knobs to OFF and unplug the stove.
Lift off the grate and remove the burner cap (it lifts straight up, no tools needed on most models).
Inspect the igniter tip — the small white ceramic electrode in the centre of the burner base.
Use a dry toothbrush to gently scrub the igniter tip and the area around it. Never use a metal brush.
Use a toothpick to remove food jammed in the igniter port or burner ports.
Wipe the burner base area with a damp cloth, then dry thoroughly with a paper towel.
Reinstall the burner cap and grate, plug in the stove, and test.

Never spray cleaners directly on the igniter. Oven cleaner, degreaser, and all-purpose spray cleaners contain chemicals that can damage the igniter ceramic or corrode the contacts. Apply cleaner to a cloth or paper towel and wipe around the igniter, not on it.

Cause 3: Cracked Igniter Ceramic

The white ceramic casing around the igniter electrode acts as an insulator that directs the spark to the exact right point to ignite the gas. If the ceramic cracks — from impact, thermal stress, or an aggressive cleaning tool — the electrical current can arc to the wrong location, causing continuous or erratic clicking that doesn't stop even after drying and cleaning.

Inspect the igniter tip closely. Use your phone camera to zoom in. Any chip, crack, or discolouration on the ceramic surface is a sign the igniter needs replacement. A replacement igniter for most gas stove brands costs $15–$45 in parts, but installation requires accessing the wiring under the cooktop and is best handled by a certified technician.

Cause 4: Stuck or Misaligned Burner Cap

The burner cap must sit perfectly flat and centred on the burner base. If it's tilted, cocked to one side, or has a chunk of food debris underneath one edge, it creates an uneven gap between the cap and the igniter. This can cause the igniter to fire continuously because the spark never quite reaches its intended target and the spark module keeps trying.

Fix: Remove the burner cap, clean the burner base thoroughly, and replace the cap by pressing it straight down and rotating slightly until it seats flat. It should not wobble or rock when pressed. If the cap is warped from heat, it may need replacement.

Cause 5: Faulty Igniter Switch

Each burner knob on a gas stove is connected to an igniter switch. When you turn the knob to start position, the switch closes and sends a signal to the spark module to fire that burner's igniter. If the switch is stuck in the closed position — from physical damage, food contamination inside the switch body, or worn contacts — the igniter fires continuously even with the knob at OFF.

Symptoms of a faulty igniter switch:

Clicking continues when the knob is turned to OFF or the stove is in standby.
Clicking is isolated to one specific burner regardless of what you do.
The clicking started after a large spill went into the burner knob area.

A faulty igniter switch requires disassembling the control panel to access and replace. This is not a safe DIY repair due to proximity to gas line connections inside the stove body.

Cause 6: Faulty Spark Module (Control Module)

The spark module is the central controller that receives signals from each igniter switch and sends power to each igniter electrode. If the spark module itself is faulty — typically from moisture damage, age, or a power surge — it may send continuous signals to one or all igniters, causing persistent clicking across multiple burners.

A spark module failure is diagnosed by first ruling out all local causes (moisture, debris, cracked ceramic, faulty switch). If two or more burners click continuously and cleaning doesn't help, the spark module is the likely culprit. Replacement costs $150–$280 depending on the brand and model.

Frequently Asked Questions

The most common reason is moisture on or around the igniter. Water from a boilover or cleaning gets into the igniter and causes constant clicking until it dries. Other common causes include food debris jammed under the burner cap, a cracked igniter ceramic, or a stuck burner cap. If clicking continues after everything is clean and dry, a faulty igniter switch or spark module needs replacement.

If the burner is lit and the igniter keeps clicking, it is annoying but not immediately dangerous. If gas is coming out but the igniter isn't sparking correctly, there's a small risk of gas accumulation. Turn off the burner knob, ventilate the kitchen, and do not use the burner until the igniter is fixed. If you smell gas strongly, leave the home and call your gas provider.

Start by removing the burner cap and grate, then cleaning the igniter tip and the area around it with a dry toothbrush. If moisture is the cause, use a hair dryer on low heat to dry the area thoroughly, or leave the burner off for a few hours. Realign the burner cap flat on the burner base. If the clicking continues after cleaning, the igniter switch likely needs replacement.

The white ceramic piece is the igniter itself — a spark electrode covered by a ceramic insulator. The ceramic keeps the electrical current focused at the tip where it sparks to ignite the gas. If the ceramic is cracked or chipped, the spark can arc to the wrong location, causing continuous clicking or no spark at all. A cracked igniter ceramic requires full igniter replacement.

Yes — cleaning the igniter is a safe DIY task. Turn off all burner knobs and unplug the stove or switch off the breaker first. Remove the grate and burner cap, then use a dry toothbrush or stiff brush to clean debris from around the igniter tip. Use a toothpick to remove food jammed in the igniter port. Never use water directly on the igniter or spray cleaners near it.

A single igniter switch replacement typically costs $80–$160 including parts and labour. If the spark module (control board) needs replacement, expect $150–$280. Nick's Appliance Repair charges $89 for diagnostics, waived when you proceed with the repair. Save an additional $40 with our limited-time promo.

If only one burner is clicking, the problem is almost certainly local to that burner — moisture, debris, or a damaged igniter on that specific burner. On some gas stove models, all igniters are controlled by a single spark module, but individual igniter switches handle each burner. A single clicking burner with no clicking on the others points to a moisture, debris, or individual switch problem rather than the spark module.
