Nine times out of ten, a GE gas oven that will not heat is caused by a weakened glow-bar igniter that lacks the amperage to open the gas valve. If the range top burners work but the oven stays cold, you should check for a glowing igniter or a blown thermal fuse.
Look, if you ignore a weak igniter and just keep using the oven, you're grinding away at your control board too. I've gone out to jobs where someone waited four months and ended up needing a $180 board that would've been totally fine if they'd just swapped the $60 igniter when it first started acting slow. Fix it now. Also, a no-heat oven is a food safety issue every single time you think something is cooking through but it's not.
OK here's the deal. GE gas ovens not heating is honestly one of the most fixable things I get called out for. The igniter is a wear-and-tear part, no different than a brake pad, and it usually just needs replacing. Parts are cheap and widely available. You're looking at a $50-80 fix if you DIY it, or $250-350 if you call someone like me. Most of the time it's not the gas line, not the control board, not some mysterious computerized fault. It's just a tired little igniter.

Symptoms You May Notice
You set it to Bake at 350, hear one click, and then the oven just sits completely cold for 15 minutes with no smell of gas and no glow at all.
The igniter glows dull orange for 60-90 seconds and then the oven cycles off without ever lighting the burner, then tries again, over and over.
Top burners work perfectly fine but the oven won't heat at all, which tells you the gas supply itself is fine.
The broiler fires up no problem but the bake burner is totally dead, or you've got the exact opposite situation.
Preheat started taking way longer than normal, like 30-40 minutes to reach 350, and some days it gets there and some days it just gives up.
Can you reset a Ge oven to clear the NO-HEAT code?
Unplug the oven from the wall or flip its circuit breaker off. Wait a full 60 seconds. Not 10, not 30. A full minute. Restore power. On GE ranges this clears any latched faults in the control board. Run a Bake cycle at 350 and watch the igniter. If it lights now, great. If it still doesn't light, you've confirmed it's a hardware issue and no amount of resetting is going to fix it.

Frequently Asked Questions
Why does my GE oven glow orange but never light?
That's a classic weak igniter. The silicon carbide element ages over time and its resistance creeps up. It can still get hot enough to glow, but it can't draw the 3.2+ amps that the gas valve needs to see before it'll open. The valve has a bimetal strip inside that physically requires that specific current to flex open. Think of it like a circuit breaker in reverse, it only opens when enough current flows through it. So the igniter looks like it's trying but it's too old and tired to finish the job. New igniter, usually $50-80 OEM, fixes it.
Can I light a modern GE gas oven with a match if the igniter fails?
Nope, don't try it. Modern GE ovens use a safety valve that requires electrical current from the igniter to stay open. There's no manually operated valve in the oven burner circuit. Without a functioning igniter sending current through the valve, gas won't flow to the burner tube no matter what you do at the other end. This is a safety design, not an accident. Holding a match near the burner port while the gas is on is genuinely dangerous and won't work anyway.
How long do GE oven igniters usually last?
In a normal household I see them go 5 to 7 years, sometimes longer if you don't use the self-clean. Self-clean is brutal on igniters. The cavity hits 900-plus degrees and that thermal shock stresses the silicon carbide element every single time. I've seen igniters fail after just 3-4 self-clean cycles on a fairly new oven. Honestly, if your oven is still heating but taking forever to preheat, that's the igniter starting to weaken. Catch it then and you're paying $60 in parts. Wait till it dies completely and you might be paying for a service call.
Does a bad control board cause a GE oven not to heat?
It can, but it's pretty rare compared to igniter failure. Probably accounts for maybe 5% of the no-heat calls I run. Here's how to tell. If the display is totally blank or you don't hear any click at all when you press Bake, the board might be dead. But if the display works, the oven clicks, and the igniter glows, the board has already done its job. It sent power to the igniter. Everything after that point is igniter, thermal fuse, or gas valve. Don't buy a $150-200 board before you've ruled out those three things.
How much does it cost to fix a GE gas oven that won't heat?
DIY, you're probably looking at $50-100 for a quality OEM igniter, maybe $15-20 if it turns out to be just a thermal fuse. If you call a pro, expect $250-350 all in depending on your area. The igniter itself takes maybe 20 minutes to swap once you're in there. Worth doing yourself if you're comfortable pulling panels and working around 120V stuff with the power disconnected.
What's the GE igniter part number I need?
For most GE 30-inch gas ranges from the last 15 years, you're looking at WB13K21 or WB2X9154. But pull your model number off the label inside the oven door frame and look it up specifically before you order. GE's parts site and most appliance parts retailers let you search by model number. Don't grab a universal igniter from the hardware store. The amperage rating matters on these ovens. You need the igniter that's spec'd for your specific gas valve or you'll be right back to square one.
Is it worth repairing an older GE gas oven that won't heat?
Depends on how old we're talking. If the oven is 8-10 years old and it's just the igniter, absolutely fix it. The body of that oven probably has another 10 years in it easy. I'd hesitate if it's 15+ years old and needs both the igniter and the gas valve, because at that point you're putting $150-200 in parts into something that might have another issue around the corner. But a single igniter swap on a 10-year-old GE? Yeah, do it yourself, it takes 30 minutes.
