Gas Cooktop Igniter Replacement

Quick Answer

A gas cooktop igniter is the ceramic probe that sparks to light the burner. If your burner clicks without lighting, the most common fix is replacing the faulty igniter electrode.

Here's what I tell people when they call me about this: a clicking burner that won't light is almost always the igniter, and it's one of the easier fixes you can do yourself. Ignore it too long and you're manually lighting your stove with a match every morning, which gets old fast and isn't exactly the safest habit. Parts run $15-40, job takes 30 minutes.

What Does the IGNITER Code Mean?

Most igniters are built to last roughly 10 years, but they're extremely sensitive to impact and moisture. I replaced three of them last Tuesday, all failed early because someone boiled something over and soaked the electrode. If your spark looks orange or yellow instead of a crisp blue, it's already on its way out and it's only a matter of time before you're reaching for a lighter.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Spilled food or grease buildup fouling the tip45%

Physically cracked ceramic insulator25%

Moisture from cleaning shorting the electrode15%

Wiring harness or spark module failure15%

Symptoms You May Notice

You turn the knob to Lite and hear clicking but nothing catches, not even a flicker, even after waiting 10 seconds.
You can actually see the spark jumping out the side of the white ceramic instead of arcing up to the burner head, which means the ceramic cracked.
The igniter keeps clicking continuously even after the flame is lit and the only way to stop it is turning the burner off entirely.
The spark looks orange or reddish instead of that sharp blue-white arc, which means it's weak and the ceramic tip is probably contaminated or failing.
Every other burner lights on the first click but this one specific burner refuses to light every single time.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Can I light my gas cooktop with a match if the igniter is broken?

Yeah, you can. Hold a long-reach lighter or match near the burner ports, then turn the knob to Lite. But don't let the gas run more than a second or two before you get a flame going, you don't want gas building up around the burner. It's totally fine as a short-term workaround while you wait for the part to arrive. Just don't do it if you smell gas before you've even turned the knob, that means you've got a different problem that needs attention first.

Why do all my burners click when I only turned one knob?

Completely normal. The spark module fires all the igniters at the same time when any knob goes to Lite, that's just how the system's designed. Only the burner with gas flowing will actually ignite. So if you hear all four clicking but only one lights, that's exactly right. Now if all four are clicking and none of them will light at all, that's a different situation and you're probably looking at a failed spark module rather than an individual igniter electrode.

Can I use an aftermarket igniter or do I need the OEM part?

I always recommend OEM or an exact-match replacement. The ceramic length and the height of the tip above the burner base have to be right or the spark gap will be off and it won't light reliably. I've put in generics that looked identical and they clicked but never lit. Spent $18 and wasted an hour. Go to the manufacturer's parts site or a trusted retailer like Repair Clinic or PartSelect, search your exact model number, and get the right one.

What if the igniter won't stop clicking after the burner is lit?

That's almost always moisture in the switch behind the knob. If you cleaned the cooktop recently and water got in around the knobs, let it air out for 24 hours. You can also set the burner to a low flame for a few minutes to help dry it out from underneath. If it's still clicking nonstop after that, one of the igniter switches behind the knob has failed and needs to be replaced. The switch itself is usually $10-20 and it's not a bad swap.

Is it worth calling a repair tech or should I just do this myself?

Honestly, for most people this is worth doing yourself. Parts are $15-40 depending on your brand, and the job takes 30-45 minutes. A tech visit runs $150-250 minimum once you factor in the service call fee and labor. The main reasons to call someone are if you open it up and find damaged wiring throughout the unit, if your cooktop is still under warranty, or if you're just not comfortable working around gas lines. But the igniter swap itself is genuinely one of the more beginner-friendly appliance repairs out there.
