A weak glow bar igniter is the most common reason a GE gas oven fails to reach temperature. While it may still glow, it often lacks the amperage needed to keep the gas valve open consistently throughout the bake cycle.
Most of the time when I see this, the oven's been slowly getting worse for months and the homeowner just figured they were imagining it. That weak igniter isn't just annoying, it can let gas build up before ignition, which is actually a safety issue. Ignore it long enough and you'll either have a total no-heat situation or a puff-ignition every time the oven cycles on. Get it fixed soon.
Nine times out of ten, this is an amperage issue, not a total part failure. I've seen this on GE ovens probably three times a week over the years and it's almost never the thermostat everyone assumes it is. The igniter degrades slowly, and by the time it's causing real problems it usually still glows, which fools people into thinking it's fine. It's not fine. It just doesn't have the juice to hold that gas valve open anymore.

Symptoms You May Notice
Preheat takes 25 to 35 minutes to hit 350 degrees when it used to take 12 to 15.
You can see the igniter glowing orange in there but a flame never actually shows up, or it takes way too long.
Cookies come out raw and doughy in the middle but the edges are browned.
The oven temp swings 30 to 50 degrees above and below the set temp instead of holding steady.
There's a faint whiff of gas right when it's trying to ignite, especially on the first use of the day.
Can you reset a Ge oven to clear the GE-GAS-LOW-HEAT code?
Flip the range's circuit breaker off for 30 full seconds, then back on. If there's a control lockout or any error on the display, press and hold the Clear/Off button for 3 seconds after power's restored. Give the board about 2 minutes to fully reinitialize before you try to run a bake cycle and see if the issue clears.

Frequently Asked Questions
Why does my GE oven take 30 minutes to reach 350 degrees?
That's almost always a weak igniter. Here's what's happening: the igniter's taking longer to get hot enough to crack open the gas valve, and it might be cycling on and off during preheat instead of holding steady. Every time it cycles off, you lose all that heat buildup and start over. I've seen igniters drag preheat out to 40 minutes before they finally quit completely. The part itself is usually 30 to 60 bucks depending on the model, and it's one of the simpler fixes on a gas range.
Can I still use the oven if it's not heating up enough?
Honestly, I wouldn't. A weak igniter means there's a window of time where gas is flowing but nothing's lit yet. Usually it's a fraction of a second, but when the igniter's really struggling, that window gets longer. You end up with a small gas buildup before ignition, and that's what causes the little puff or thump you might hear sometimes. It's not going to level your kitchen, but it's not a good situation and it always gets worse, never better. Fix it before it becomes a total no-heat call.
How do I know if my GE oven igniter is weak or dead?
Visual inspection doesn't tell you much, that's the frustrating part. A dead igniter won't glow at all, that's easy to spot. But a weak igniter glows just fine, it just doesn't pull enough current to trigger the gas valve. You need an amp clamp meter to know for sure. Anything below 3.2 amps and it needs to go, even if it looks totally normal glowing away in there. I've shown homeowners their igniter glowing and had them argue with me that it looks fine. Then I show them 2.1 amps on the meter and that usually settles the debate.
Is it worth repairing a 10 year old GE gas oven?
Yeah, usually. Gas ranges last 15 to 20 years with normal use, so a 10 year old oven's got a lot of life left. If it's just the igniter or the temp sensor, you're talking 30 to 80 bucks in parts and maybe an hour of your time. Even if you pay a tech, you're probably looking at 150 to 200 total, which is way less than a new range. The only time I'd say skip the repair is if the bake burner, the broiler, and the igniter are all failing at once, because that starts to point at a board problem and the math changes pretty fast.
Why is the top of my food burnt but the middle is cold?
This one's actually interesting. Some GE boards will fire up the broil element to help assist preheat. So if your bake burner isn't staying lit, the broil element tries to carry the whole load from the top of the oven. You end up with a ton of heat from above and almost nothing from below. Whatever you're baking just sits there getting warmed from the top while the middle and bottom lag way behind. Classic sign that your bake burner's not holding a flame through the full cycle.
What does a bake igniter replacement actually cost on a GE range?
Parts run 30 to 65 dollars depending on the model. The GE WB13K21 is the most common one and it's usually around 40 bucks online. If you're hiring a tech, expect to pay 150 to 220 total with labor. It's a pretty straightforward repair, maybe 45 minutes if you've never done it before. You pull the oven racks, lift out the floor panel, disconnect two wires and back out two screws, swap the igniter, and put everything back. Not a lot that can go wrong.
