Most of the time, a gas burner that won't light is a dirty ceramic cap or a little trapped moisture, and you can fix it without spending a dollar. At My Appliance Repair, the calls we get where the actual part is the problem — and that part costs real money — are probably one in five. The other four are something you can handle yourself in under thirty minutes if you know what you're looking at.
Three separate things can stop a gas burner from lighting
The ceramic igniter cap sits directly on top of the burner. It's the little dome-shaped piece, usually white or off-white, that you can lift right off with your fingers. These crack from thermal cycling — the constant heat-up and cool-down over years — and a cracked cap breaks the spark gap just enough to kill ignition. GE and Frigidaire gas ranges from roughly 2012 to 2019 have this problem more than anything else we see, almost always on the front-left burner because that's the one people actually use. A replacement cap runs $8 to $14 depending on brand, and swapping it takes five minutes.
Below the cap is the igniter electrode — a small ceramic post with a metal tip that produces the spark. Grease and food debris pack into the tip and block the spark. This one you clean, not replace. A toothbrush and a little patience usually handles it.
Then there's the spark module, which is the control board that sends voltage out to every igniter on the range. That's the expensive one. On an older Frigidaire slide-in where the spark module is integrated into a larger control board, we've seen parts quotes over $300 for a range that isn't worth $400. Don't fix that. But the module fails a lot less often than people assume, and it's almost never where the diagnosis lands.
Clicking that won't stop is usually not a broken part
If the burner keeps clicking after you release the knob, that's moisture in the igniter well — almost always from a boil-over. Soup, pasta water, anything that spills under the burner cap leaves water sitting on the electrode contacts, and the igniter keeps sparking because it reads that as an unlit burner. It's not broken. It's wet.
Dry it out before you assume anything is wrong:
- Pull the burner cap off and blot what you can with a dry cloth or paper towel.
- Set your oven to 170°F for 20 to 30 minutes with the burner area open to the heat.
- Let everything cool completely, set the cap back on, and try again.
Humidity makes this worse in summer, so if this happens in July and the clicking lingers longer than expected, that's why. No click at all is a different problem — that points to the electrode or the module, not moisture.
The free diagnostic most people skip
If one gas burner won't light and the others work, pull the igniter cap off the dead burner and swap it with the cap from a working one. Same range, same model — they're interchangeable. Here's what each outcome tells you:
- Dead burner fires with the working cap: You have a cracked cap. Cost to fix: $8–$14.
- Dead burner still won't fire: The problem is the electrode or wiring beneath it, not the cap.
That one swap tells you almost everything you need to know and saves you the diagnostic fee.
A Tuesday in Hamden
A homeowner called My Appliance Repair about her front-left burner clicking nonstop for two days. She'd already ordered a new range. We came in, pulled the igniter cap — it was wet from a boil-over two days earlier — dried everything out, and set the cap back on. Burner lit on the first try. She canceled the range order. The visit was 18 minutes, and we barely touched a tool. That's not a rare outcome. That's just what happens when you know what to look for.
Where the cost line actually is
Here's a quick breakdown of what these repairs actually cost in Connecticut:
- Ceramic igniter cap: $8–$14 in parts, five minutes to swap.
- Igniter electrode (e.g., GE part WB13K10014): $18–$22 in parts, about 25 minutes labor.
- Spark module: $90–$160 in parts — and up to $300+ on integrated boards. This is where you call someone, because you're working with line voltage.
- Gas valve replacement: Licensed repair only. Do not DIY this one.
If your range is over 15 years old and the spark module is gone, price a replacement before authorizing the repair. The math usually doesn't work in the module's favor on an old machine.
