How long do gas oven igniters last?
Gas oven igniters on the Magic Chef 31213WAV typically last about 3 to 5 years in normal home use. Heavy use (multiple long bakes daily) and frequent preheating can shorten that lifespan because the igniter is a wear item that heats up every time the oven starts.
What makes an igniter wear out faster
- Long bake times and frequent preheats (more heat cycles)
- Grease or food spills that bake onto the burner area
- Weak gas flow or a dirty burner that forces longer ignition times
- Power issues (loose wiring connections, heat-damaged wires)
- Slamming the oven door (can stress wiring and mounts)
Signs the igniter is near the end of its life
- Oven takes longer than usual to light (often 60 to 90+ seconds)
- You smell gas briefly before ignition
- Burner lights sometimes, but not every time
- Oven won’t heat, but the igniter still glows (weak igniter)
Quick troubleshooting checklist (safe, practical)
- Turn the oven on and time how long it takes to ignite.
- If it is slow, inspect the burner area for baked-on debris (when fully cool).
- Check that the igniter wiring is not brittle, burned, or loose.
- If the igniter glows but ignition is delayed or inconsistent, replacement is the most common fix.
Common replacement part for this model
| What you’re replacing | Model | Example part to check |
|---|---|---|
| Oven burner igniter | 31213WAV | Oven igniter 12400035 |
Why it matters
A weak igniter can cause delayed ignition, uneven baking, and repeated failed heat cycles that put extra strain on the gas valve and ignition system. Replacing a failing igniter restores normal preheat time and reliable oven heat.

How to tell if a gas oven igniter is bad?
On the Magic Chef 31213WAV gas range, a bad oven igniter usually shows up as an oven that will not heat, heats very slowly, or has an igniter that glows but never lights the burner. The most reliable confirmation is a weak igniter that does not draw enough current to open the gas valve.
Common signs the igniter is failing
- Igniter glows but the burner never lights.
- Burner lights after a long delay (often 30 to 90 seconds or more).
- Oven temperature is inconsistent because ignition is intermittent.
- Igniter does not glow at all (could also be wiring, control, or gas valve).
- Visible damage on the igniter (cracks, white spots, or a burned area).
Quick checks you can do (safe basics)
- Turn the oven to Bake and watch through the broiler drawer opening or oven bottom vents.
- Look for a strong glow at the igniter; a weak, dull red glow often indicates a worn igniter.
- If the igniter glows but the burner does not light within about a minute, the igniter is the top suspect.
- If you smell gas without ignition, turn the oven off and ventilate; do not keep retrying.
Electrical test (best confirmation)
A hot-surface igniter can glow and still be too weak to open the gas safety valve. Using a clamp meter, many round-style igniters need roughly 3.2 to 3.6 amps to reliably open the valve (exact target varies by design).
| What you observe | Most likely cause | What to do next |
|---|---|---|
| No glow at all | Open igniter, broken wire, control issue | Inspect wiring; test igniter circuit |
| Glows, no flame | Weak igniter (low amps) | Replace igniter |
| Slow ignition | Weak igniter or restricted burner | Clean burner; replace igniter if still slow |
Parts that commonly fix “no bake” on this model
If your symptoms match the “glows but won’t light” pattern, the correct replacement to start with is the oven igniter 12400035.
Why it matters
A weak igniter can prevent the gas valve from opening, so the oven will not heat even though the igniter appears to be working. Replacing the igniter restores normal ignition timing and steadier baking temperatures.

How much does it cost to replace a gas oven igniter?
For the Magic Chef 31213WAV gas range, replacing a gas oven igniter typically costs about $150 to $325 when a technician supplies the part and labor. If you do it yourself, the igniter part is commonly $20 to $75, plus basic tools and your time; your exact total depends on the igniter style and service rates.
Typical cost breakdown
Here are the most common cost buckets we see for gas range igniter replacement:
- DIY part only: $20 to $75 (typical aftermarket range)
- DIY with OEM-style part: often $40 to $120
- Professional repair (parts + labor): $150 to $325
- Higher-end or difficult access repairs: $300+
| Scenario | What you pay for | Typical total |
|---|---|---|
| DIY | Igniter + supplies | $25 to $125 |
| Pro service | Trip/diagnostic + labor + igniter | $150 to $325 |
| Pro service (complex) | Extra labor time, multiple visits | $300+ |
Parts for this model that affect the price
On the 31213WAV, the oven may use a dedicated oven burner igniter. If your oven will not heat and the igniter does not glow (or glows weakly), pricing usually centers on the igniter itself.
What changes the final price
These factors move the total up or down:
- Service call/diagnostic fee (often applied toward the repair)
- Labor time (accessing the burner/igniter can vary)
- Part type (OEM-style vs universal)
- Related issues (burner problems, wiring damage, loose connections)
- Urgent or after-hours service
Why it matters
A weak igniter can prevent the gas valve from opening fully, so the oven may take a long time to heat or never reach temperature. Replacing the igniter promptly helps restore normal bake performance and reduces repeated ignition attempts.

Do I need to turn off gas to replace oven igniter?
Yes. For the Magic Chef 31213WAV gas range, we turn off the gas supply valve before replacing the oven igniter, and we also unplug the range (or switch off the breaker). The igniter is an electrical part, but the repair puts you near gas components.
Safe shutoff steps (recommended)
- Turn the oven and all surface burners to OFF.
- Unplug the range or turn OFF the circuit breaker.
- Turn the gas shutoff valve to OFF (typically a quarter-turn so the handle is perpendicular to the gas line).
- Let the oven cool completely.
- Ventilate the area; avoid open flames while servicing.
What to replace (model-related part)
If your oven burner will not ignite, takes a long time to light, or you smell gas before ignition, a weak igniter is a common cause. For this model, the correct replacement is the oven igniter 12400035.
Quick symptom guide
| Symptom | Most common cause | What to check next |
|---|---|---|
| No glow from igniter | No power, failed igniter, wiring issue | Outlet/breaker, harness connections |
| Igniter glows but no flame | Weak igniter (not drawing enough current) | Replace igniter |
| Flame lights after long delay | Weak igniter | Replace igniter |
| Clicking is heard (top burners) | Spark system issue (separate from oven) | Spark module, burner igniters |
Why it matters
Turning off gas and power reduces the risk of gas leakage and accidental ignition while your hands are inside the oven cavity near the burner tube, wiring, and igniter mounting screws.
After the repair: safety check
- Restore gas and power.
- Test bake ignition: flame should light within a few seconds.
- Sniff for gas around the range; if you detect gas, turn the valve back off and recheck connections.
