When an oven stops heating, the culprit is usually a burnt out bake element in electric models or a weakened igniter in gas units. Checking for visible damage on the element or a glowing igniter that fails to open the gas valve is the first step in any professional diagnosis.
In 15 years of field work, I've seen way more bad elements and igniters than blown control boards. But here's what people miss: if you ignore a dead oven, some models keep trying to run the heating circuit and can fry a relay on the board, turning a $30 fix into a $200 one. Don't sit on this one.
Nine times out of ten, an electric oven that won't heat has a physical break in the heating coil. Gas ovens it's usually the igniter, which might still glow but can't pull enough amperage to actually open the gas valve. I always check power first before I start pulling things apart, because a tripped breaker will fool you every single time.

Symptoms You May Notice
The display shows a climbing preheat temperature but the oven cavity is still room temperature after 20 minutes.
On a gas oven, you hear the igniter clicking and catch a faint whiff of gas, but the flame never actually catches.
The broiler works fine on high heat but the bake setting does absolutely nothing, which points right at the lower element.
Oven takes 45 minutes to hit 350 degrees instead of the usual 12-15 minutes.
There's a visible burn spot, crack, or hole in the black rod at the bottom of the oven, sometimes with white chalky ash around it.
Can you reset a Generic oven to clear the OVEN-NOT-HEATING code?
Flip the oven's breaker to the off position and leave it for at least 5 minutes, not just a few seconds. This clears the control board's memory. Restore power, set the clock, and run a bake cycle at 350 degrees for 15 minutes to confirm heating. If your oven has a Cancel or Clear button, try holding it for 3 seconds first before going to the breaker, since that's enough to reset most control boards.

Frequently Asked Questions
Why does my oven take so long to preheat?
Slow preheat is almost always a partially failed bake element or a bad temperature sensor. The element might look totally fine but have an internal weak spot where it's not generating full heat, so the oven creeps up slowly instead of hitting temperature in the normal 12-15 minutes. In gas ovens, a weak igniter can cause the valve to open and close intermittently, meaning you're getting heat in bursts instead of a steady flame. Grab an oven thermometer and put it inside. If the oven says 350 but the thermometer reads 280, you've got a sensor problem. If the thermometer matches but it just takes forever, you're looking at the heating element.
Can I still use the stovetop if the oven isn't heating?
Usually yes. On most ranges the cooktop burners and the oven run on separate circuits or independent gas lines, so one failing doesn't take out the other. But here's the exception: if the problem is a tripped 240V breaker at the panel, you might lose both at once since they share that circuit. For gas ranges, even if the electronic ignition acts up, you can usually light the stovetop burners manually with a long lighter. So don't assume the whole appliance is dead. Check what you've actually got before you start panicking.
How do I know if my oven igniter is bad?
The classic sign is an igniter that glows but takes way too long to light the burner, or never lights it at all. A healthy igniter should get bright orange to white hot within 30-45 seconds and pull around 3.2 to 3.6 amps. If yours glows a weak dull orange for 90 seconds and nothing happens, it's not generating enough heat to open the gas safety valve. You can sometimes hear it too: a faint pop right when the gas would normally ignite, but no flame follows. New igniters run $30-60 and take about 20 minutes to swap on most ovens, it's one of the easier gas repairs.
Is it worth repairing an older oven that stops heating?
In most cases, absolutely yes. A bake element is $20-50, an igniter is $30-60, and a thermal fuse is under $20. Even a temperature sensor is usually under $40. So if the oven's otherwise solid and it's just the heating that went out, you're looking at a repair that costs a fraction of a new appliance. Where it gets tricky is if the main control board failed, since those run $150-300 or more depending on the brand. At that point you want to weigh the board cost against the oven's age. If it's 15+ years old and needs a $250 board, sometimes it makes more sense to put that money toward something new.
What does a burnt bake element look like?
Sometimes it's completely obvious, like the element is literally split in half or there's a visible hole where it burned through. Other times it's subtle: a small blister, a spot that looks like a tiny weld bead, or a section with white chalky ash on the surface. Get a flashlight and run it slowly along the full length of the element. Even a hairline crack means the circuit is open and it won't heat. And honestly, don't just trust your eyes on this one. If you've got a multimeter, put it on continuity mode and test across the element's two terminals. No beep, no heat, end of story.
What's the difference between the bake element and the broil element?
The bake element sits at the bottom of the oven and does most of the work. The broil element is at the top and uses intense direct heat for browning. They're on completely separate circuits, which is actually useful for diagnosing your problem. If your broil works but bake doesn't, you've got a failed lower element or a bake relay issue. If neither works, you're probably looking at a tripped breaker or a blown thermal fuse cutting power to both. Some ovens also use a hidden bake element tucked below the oven floor, so if you don't see a rod at the bottom, check the model-specific diagram before assuming there's nothing there.
