How Long Does a Oven Igniter Last?
Gas oven igniters last 3 to 5 years on average, though some make it to 7 years with light use. The igniter is the component that gets hot enough to open the gas valve and ignite the burner when you set the oven temperature. There are 2 types: glow bar igniters (the most common in modern ovens) and spark igniters (less common, found in some older or commercial-style ranges). Glow bar igniters are made of silicon carbide or silicon nitride and work by drawing electrical current through the element until it reaches about 2,500°F... hot enough to glow bright orange and trigger the gas valve's safety mechanism. The gas valve won't open until the igniter draws enough amperage (typically 3.2 to 3.6 amps), which is a safety feature that prevents gas from flowing without ignition. Over time, the igniter weakens and draws fewer amps. A failing igniter might still glow but not draw enough current to open the gas valve... so you see a glowing element but no gas, no flame, and no heat. Silicon nitride igniters (the flat, rectangular ones) last slightly longer than silicon carbide (the round, cylindrical ones) and heat up faster... about 30 to 60 seconds versus 60 to 90 seconds. If your oven takes more than 90 seconds to ignite, or if preheat times have crept past 15 to 20 minutes for 350°F, the igniter is likely on its way out. This is the single most common gas oven repair... responsible for roughly 80% of "oven won't heat" service calls.
Warning Signs It's Time to Replace
Signs your oven igniter is failing or going bad
If you're seeing two or more of these, it's time to start shopping.
- ⚠️The oven takes much longer than usual to preheat — A healthy oven reaches 350°F in 7 to 10 minutes. If preheat is taking 15 to 25 minutes, the igniter is weakening. It still works, but it's drawing fewer amps and taking longer to open the gas valve. Replacement is coming soon.
- ⚠️You smell gas briefly when the oven cycles on — A slow-to-ignite glow bar lets a small amount of gas escape before it finally opens the valve and lights. If you catch a whiff of gas each time the burner kicks on, the igniter isn't reaching operating temperature fast enough. This is a safety concern.
- ⚠️The igniter glows but the oven doesn't light — This is the classic symptom. The igniter glows orange but doesn't draw enough amps (below 3.2A) to open the gas safety valve. The gas never flows, so the burner never lights. The igniter looks like it's working, but it's too weak.
- ⚠️The oven heats unevenly or food cooks inconsistently — A weak igniter causes the burner to cycle erratically. It takes too long to reignite between cycles, so oven temperature swings wider than normal... sometimes 50°F or more between cycles instead of the normal 10 to 15°F range.
- ⚠️The igniter doesn't glow at all when the oven is set to bake — A completely dead igniter means no glow, no gas, no heat. Before assuming the igniter is dead, check that the oven is getting power (the clock and controls work), the gas supply valve behind the oven is open, and the thermal fuse hasn't blown.
- ⚠️You hear repeated clicking but the oven won't ignite (spark igniter type) — For ovens with spark igniters, continuous clicking without ignition means the electrode is fouled with food residue, the gap is wrong, or the igniter module is failing. Clean the electrode first... if clicking continues without ignition, replace the igniter.
Should You Repair or Replace?
Replace the igniter, not the oven. This is one of the best-value appliance repairs you can do. A replacement igniter costs $15 to $30 for the part, and the job takes 15 to 30 minutes with basic tools. An appliance repair tech charges $150 to $250 total (parts + labor) for the same job. Given that a new gas oven costs $600 to $2,000... replacing a $20 igniter is a no-brainer. The repair is straightforward enough that most people can DIY it. You don't need to disconnect the gas line (the igniter is an electrical component), and most igniters are held in place with 2 screws and a wire harness connector. The hardest part is usually pulling the oven away from the wall to unplug it. Before buying a replacement, you need your oven's model number (on a sticker inside the door frame or on the back). Search that model number + "igniter" to find the exact replacement part. Universal igniters exist and work for many ovens, but a model-specific part is always the safer bet. One thing to know: don't touch the new igniter element with your bare hands. Oils from your skin can create hot spots that shorten its life. Handle it by the mounting bracket or use gloves.
🔧 Repair if...
- • It's less than 1 years old
- • This is the first major issue
- • Repair cost is under $4 - $9
- • The rest of the unit is in good shape
🔄 Replace if...
- • It's past 3 years
- • This is the second or third repair
- • Repair quote is over $7 - $15
- • Newer models would save you money on energy
Replacement cost: A new oven igniter typically costs $15 - $30 installed. Prices vary by region, brand, and complexity of installation.

Common Oven Igniter Repairs and What They Cost
Oven Igniter repair cost breakdown
| Repair | Typical Cost | Notes |
|---|---|---|
| Replace the oven igniter | $15 to $30 DIY, $150 to $250 with a tech | The most common gas oven repair. 2 screws, 1 wire connector, 15-30 minutes. Unplug the oven first... no need to disconnect gas. |
| Replace the gas safety valve | $50 to $120 DIY, $200 to $350 with a tech | If the igniter tests good (drawing 3.2+ amps) but gas still won't flow, the safety valve is likely stuck. Less common than igniter failure. |
| Replace the oven temperature sensor | $15 to $40 DIY, $100 to $200 with a tech | If the oven heats but can't hold temperature (swinging 50°F+ from the set point), the sensor may be faulty. Usually a 2-screw swap at the back of the oven cavity. |
| Replace the thermal fuse | $5 to $15 DIY, $100 to $175 with a tech | A blown thermal fuse cuts power to the igniter. Common after a self-clean cycle overheats the oven. Quick fix but you need your model number for the right fuse. |
| Clean or replace spark igniter electrode | $10 to $25 DIY, $80 to $150 with a tech | For spark-type igniters. Clean the electrode tip first with a brush. If that doesn't fix it, the igniter module ($20-$40) or electrode ($10-$25) needs replacing. |

How Long Does It Take to Replace a Oven Igniter?
Replacing a gas oven igniter takes 15 to 30 minutes. No special tools needed... just a 1/4-inch nut driver or socket, a Phillips screwdriver, and optionally a multimeter if you want to test the old igniter first.
Step-by-step: pull the oven away from the wall and unplug it (you do NOT need to shut off the gas... the igniter is purely electrical). Remove the oven racks, the oven floor panel (usually 2 to 4 screws), and the heat shield beneath it to expose the burner and igniter. The igniter is attached to the burner assembly with 2 screws and connects to the wiring harness with a plug or 2 wire nuts. Remove the screws, unplug the connector, and the old igniter comes out. Install the new one in reverse order.
The critical detail: handle the new igniter by its mounting bracket only. Don't touch the glowing element with bare hands. Skin oils create hot spots that can cause premature failure. If you do touch it, clean it gently with rubbing alcohol before installing.
Want to test the old igniter before buying a replacement? Set your multimeter to ohms and touch the probes to the igniter terminals. A good igniter reads 40 to 400 ohms. Open circuit (infinite resistance) means it's dead. You can also use an amp clamp while the igniter is installed and powered... it should draw 3.2 to 3.6 amps. Below 3.0 amps means it won't open the gas valve even if it glows.
How to Make It Last Longer
- ✓Keep the oven floor clean. Food spills and grease that drip onto or near the igniter can coat the element and reduce its effectiveness. Wipe up spills after the oven cools.
- ✓Avoid using the self-clean cycle excessively. The extreme heat (900°F+) accelerates igniter wear. Once or twice a year is fine, but monthly self-cleaning can cut igniter life in half.
- ✓Don't slam the oven door. The igniter element is fragile... especially silicon carbide igniters, which are brittle ceramic. Repeated vibrations from door slamming can crack the element.
- ✓If your oven has a spark igniter, clean the electrode tip every 6 months with a soft brush or toothbrush. Food residue on the electrode prevents proper sparking.
- ✓Check the igniter glow color occasionally. A healthy igniter glows bright orange within 60 seconds. If it glows dim orange or takes more than 90 seconds to reach full brightness, it's weakening.
