What the Igniter Does and Why It Fails
The igniter serves two functions: it generates the spark or glow that ignites the gas, and it acts as a safety valve that must draw sufficient current before the gas valve opens. Gas oven igniters are typically the glow-bar type — a silicon carbide element that heats to approximately 2,500°F. Over time the element degrades, draws less current, and eventually fails to open the gas valve even when it appears to glow. Average igniter lifespan: 5-7 years under normal use.
Diagnosing Igniter Failure
| Symptom | Likely Cause | Action |
|---|---|---|
| Oven clicks but doesn't light | Igniter failing to open gas valve | Replace igniter |
| Igniter glows but oven doesn't heat | Weak igniter not drawing sufficient current | Replace igniter |
| No glow at all | Igniter broken or no power | Check wiring, replace igniter |
| Stovetop lights, oven doesn't | Oven-specific igniter failure | Replace oven igniter |
| Gas smell without ignition | Safety issue | Stop — call a technician |
The DIY Repair Process
What you need: Replacement igniter (model-specific), Phillips screwdriver, nut driver or socket set, 30-60 minutes.
General process: Turn off gas supply at the shutoff valve. Remove oven racks. Remove the oven bottom panel. Locate the igniter at the back of the oven floor or connected to the burner tube. Disconnect the igniter wire connector — no tools needed. Remove the igniter mounting screws. Install the new igniter and reverse the process. Turn gas back on and test. Model-specific tutorials available on YouTube and RepairClinic for virtually every brand.
Safety note: Never attempt igniter repair if you smell gas — turn off the range, ventilate the area, and call a technician.
The Financial Math — Why This Repair Almost Always Makes Sense
| Range Age | Repair Cost | Range MSRP | % of MSRP | AM Score | Recommendation |
|---|---|---|---|---|---|
| 5 years | $185 | $1,099 | 17% | 23 | Repair — clear |
| 8 years | $185 | $1,099 | 17% | 31 | Repair — clear |
| 10 years | $200 | $1,099 | 18% | 38 | Repair — clear |
| 12 years | $220 | $1,099 | 20% | 44 | Repair with Caution |
Lifespan Extension Value
| Repair at Year | Remaining Expected Life | Repair Cost | Cost Per Year of Extended Life |
|---|---|---|---|
| 5 years | 8 – 10 years | $185 | $19 – $23/year |
| 8 years | 5 – 7 years | $185 | $26 – $37/year |
| 10 years | 3 – 5 years | $200 | $40 – $67/year |
Even at year 10, paying $200 to extend a gas range's life by 3-5 years is an exceptional financial decision — the equivalent of $40-$67 per year for a fully functional range that would cost $1,099+ to replace.
