Replacing an oven igniter typically runs $200 to $350 for parts and labor combined in high-cost California markets like the Bay Area. Nationally the range is somewhat lower, but local labor rates and trip fees push Bay Area jobs to the higher end. The igniter itself is usually $20 to $60 for common brands; the rest is labor and the trip fee.
Here’s what actually happens, why igniters fail, and how to know if that’s really your problem.
How a Gas Oven Igniter Works
The igniter does two jobs: it glows hot enough to light the gas, and it draws enough current to open the safety valve that lets gas flow. If it weakens, the valve may not open fully, or gas won’t ignite at all. Most igniters are glow bars made of silicon carbide or silicon nitride; silicon carbide models are typically flat and rectangular, while silicon nitride models can be rod-shaped. They’re fragile and they degrade over time.
Electric ovens don’t have igniters in the same sense. If you have an electric oven that won’t heat, you’re looking at a bake element or broil element, not this repair.
Most Likely Causes (in order)
Weak igniter. This is the most common failure. The igniter glows but either won’t reach ignition temperature or won’t draw enough current to open the gas valve. You’ll often see it glow orange but hear no “whomp” of ignition, or the oven takes five or more minutes to light. A tech can measure the draw with a clamp meter to confirm.
Cracked igniter. Igniters are ceramic and crack if something drops on them, if moisture hits them while hot, or just from age. A cracked igniter usually won’t glow at all.
Wiring or connector issue. The harness that connects the igniter sometimes burns or corrodes, especially near the back of the oven floor. This looks identical to a bad igniter on the surface. A tech will check the harness before ordering a part.
Gas valve failure. Less common, but if the igniter checks out electrically, the valve itself may have failed. This is a more involved repair and costs more.
What the Diagnosis Looks Like
A tech will pull the oven bottom panel, visually inspect the igniter for cracks, then test it electrically with a clamp meter to measure current draw. The whole diagnostic takes maybe 15 minutes. If the igniter measures out of spec, it gets swapped. If the igniter looks fine, the tech checks the safety valve and the wiring harness before quoting a different repair.
Most brands use igniters that are widely available. Whirlpool, GE, Frigidaire, Samsung, and LG all use flat-bar igniters; they’re not exotic parts. Thermador and Wolf use similar designs but the parts run significantly more, and may need to be special-ordered depending on the model.
What the Repair Costs
Parts run $20 to $60 for most common brands. Labor for the swap itself is about 30 to 45 minutes of work. Add the diagnostic fee and trip charge, and the all-in number in the Bay Area is typically $200 to $350. Get a written quote before any work starts; the diagnostic fee is usually applied toward the repair if you proceed.
A few things that push the number up:
- Slide-in or built-in ovens that require more disassembly
- Double ovens (labor is similar, but confirm which burner is affected)
- Less common brands where the part has to be special-ordered
- If the wiring harness also needs replacement
Why This Is a Pro Job
The igniter is accessible, but it’s attached to a gas appliance. Any work in that area requires a proper leak check before the oven goes back into service. That’s not a step you skip, and it’s not something you can do reliably without the right equipment.
The diagnosis matters too. A glowing igniter that won’t light looks exactly like a bad safety valve from the outside. Without a clamp meter, you’re guessing. Buy the wrong part and the oven still doesn’t work, and now you’re out the part cost on top of a service call anyway.
A tech confirms the cause first, uses the correct replacement for your specific model, and backs the work with a warranty. That’s worth more than the part markup.
When It’s Not the Igniter
A few symptoms that suggest something else is going on:
- Oven lights but won’t hold temperature. Could be the temperature sensor or control board.
- Burners on the cooktop work fine, but the oven won’t light. The cooktop uses a different ignition system. This narrows it to the oven igniter or valve specifically.
- Error code on the display. Modern ovens will often flag a sensor failure with a code. That’s usually not the igniter.
- Clicking but no flame on a surface burner. Gas range surface burners use spark ignition, not a glow bar. Continuous clicking there is a separate issue from the oven igniter.
