Think of the igniter as the gatekeeper for your oven's heat. If you see a faint orange glow but the burner never lights, or if there is no glow at all, the igniter has likely lost the strength to open the gas valve.
A weak igniter is the number one reason gas ovens stop heating, and I see this repair probably twice a week. The tricky part is that a failing igniter still glows, so most people assume it's fine. Don't ignore that slow ignition. Gas can build up in the oven cavity before the burner finally catches, and that's how you get a scary 'whomp' when it does light. Fix it now.

What Does the IGNITER Code Mean?
So your GE oven isn't lighting or it's taking forever to heat up. Nine times out of ten, it's the igniter. Parts run about $25-40, the job takes maybe 45 minutes, and you don't need to be an appliance tech to pull it off. I've done this repair probably a hundred times and honestly it's one of the cleaner DIY fixes you'll find on a gas oven.
Most Likely Causes

Contamination from spills10%
Electrical failure in harness10%
Symptoms You May Notice
Your oven takes 5+ minutes to preheat to 350 when it used to hit temp in half that time. Something's clearly off even if it technically works.
You can see an orange glow through the bottom vents but the gas never catches. That orange glow is actually the problem, not a good sign. It should be white-hot.
Strong gas smell when you turn the oven on, especially in the first minute or two. Gas is flowing but the igniter can't light it fast enough, so it just sits there building up.
You look through the bottom vent and there's nothing at all. No glow, no click, nothing. Dead igniter.
The oven clicks repeatedly like a wet surface burner but nothing ever happens and no flame appears.

Frequently Asked Questions
My igniter is glowing orange but the oven won't light. What's going on?
This is the failure mode that confuses everyone and I explain it probably three times a week. The igniter doesn't just light the gas, it also has to draw enough electrical current to open the gas safety valve. As igniters age, their resistance drifts and they can still get hot enough to glow orange, but they don't pull enough current to trigger that valve. No valve opening means no gas flow. So the igniter sits there glowing uselessly while your kitchen smells like gas. New igniter fixes it. Don't mess with the gas valve first.
Can I use a universal igniter on my GE oven?
Honestly, I don't recommend it. Universal igniters technically fit a lot of ovens but GE ovens are calibrated for a specific amperage draw, and using the wrong igniter can cause slow ignition or put stress on the safety valve over time. The OEM GE part usually runs $25-40 and it's worth it. Check the label inside your oven door for your model number, then look up the part. WB13K21 and WB2X9154 are two of the most common flat igniters for GE ranges. Grab the right one.
Why can't I just touch the new igniter with my hands?
The black element is silicon carbide or silicon nitride and it's incredibly porous. Your skin oils soak into those microscopic pores. When the igniter heats up to over 2,000 degrees, those oils burn in and create a weak spot called a hot spot. That hot spot causes the ceramic to crack and the igniter fails almost immediately, like sometimes on the very first use. Handle it by the metal bracket only. If you need to support the element, use the plastic bag it came in as a makeshift glove. I've seen people kill a brand new $35 igniter this way and it's a heartbreaking waste.
How do I know if I need a flat or round igniter?
Check your model number first, but generally GE ovens from the last 20 years or so use the flat style. Older ovens from the 80s and early 90s mostly used the round style. Honestly, the safest move is to pull the old igniter out first and look at it before you order anything. Also check the wire connector type because those vary too. Snap a photo of the old igniter and the connector before you remove it, then use that to match your new part. Takes 30 seconds and saves you from a return shipping headache.
How long does this repair actually take?
If you've never done it before, plan on about an hour and give yourself some breathing room. I can swap an igniter in around 20 minutes at this point but that's after doing it way more times than I can count. The hardest part is usually the floor panel screws if they've rusted a little, or just figuring out the layout of your specific model. The actual swap is simple. If you can find a YouTube video for your exact model number, watch it once before you start. The physical repair takes maybe 15-20 minutes once you know where everything is.
