Samsung oven not heating up: check the most common cause first (see step 1 below). Samsung uses brand-specific components that differ from other manufacturers.
Most of the time when a Samsung oven stops heating, it's one of three things: burned-out bake element, a weak igniter on gas models, or a blown thermal fuse. Ignoring it won't make it better and it won't fix itself. Left alone, a failing gas igniter can start letting gas through without igniting it, which is not a situation you want in your kitchen.
OK so here's the deal with Samsung ovens not heating. It's almost always the bake element on electric models, or the igniter on gas. Samsung uses a specific bake element that runs $25-40, and it's honestly one of the easier oven repairs out there. The igniter on gas models is a little pricier at $40-80 but still pretty DIY-friendly. I replaced three Samsung igniters last month alone, so this is not some rare thing.

Symptoms You May Notice
You set the oven to 350 degrees, wait 20 minutes, and it's still cold. Not slow to preheat. Just cold.
The display shows a temperature climbing but the oven interior is noticeably cool when you carefully reach in. That's usually a failing temp sensor lying to the control board.
On gas models, you hear the igniter clicking or you can actually see it glowing orange, but no burner flame ever appears.
The oven works fine on broil but not bake, or vice versa. That's a strong sign just one element is out, not the whole system.
Visible burn marks, actual breaks, or blisters on the bake element sitting at the bottom of the oven cavity.
Can you reset a Samsung oven to clear the NOT-HEATING code?
Unplug the oven completely from the wall outlet. Don't just flip the breaker. Wait a full 60 seconds. Plug it back in, set it to bake at 350 degrees, and give it 15 minutes to see if heating kicks on. For gas models, confirm the supply valve behind the unit is fully open. A reset clears control board glitches but won't fix a burned element or blown fuse.

Frequently Asked Questions
How much does it cost to fix a Samsung oven not heating up?
Depends on the cause. A bake element runs $25-50 for the part and it's a 30-minute DIY job if you're comfortable with a screwdriver. Igniter on a gas model is $40-80. Temp sensor is $15-25. Thermal fuse is like $10. Control board is where it gets painful, $150-300 for the part alone. If you're hiring a tech, add $100-200 for the service call on top of whatever parts they install.
Is it worth repairing a Samsung oven not heating up?
Usually yeah. If it's under 8 years old and you're looking at an element, igniter, sensor, or fuse, just fix it. Those are all under $100 in parts and under an hour of work. If you're staring down a $250 control board on a 10-year-old oven and a new range is $600, that's where the math gets harder. Samsung's standard warranty is 1 year, so if yours is recent, check that before spending anything.
Can I fix a Samsung oven not heating myself?
For electric ovens, yes. Replacing the bake element takes a Phillips screwdriver and maybe 20 minutes once you've done it once. The temp sensor and thermal fuse are just as straightforward. Always unplug it first, no exceptions. For gas ovens, swapping the igniter is also doable if you're comfortable and you shut the gas off first. Anything involving the actual gas valve or gas line connections though, call a pro. Don't touch the gas supply hardware yourself.
Why does my Samsung oven heat on broil but not bake?
That's actually a useful clue. It means your broil element is working fine but your bake element is burned out. They're completely separate components. Pull your racks out and look at the bake element on the floor of the oven. You'll probably see a visible break or burn spot right there in the coil. It's one of the most common and cleanest oven repairs there is, and the Samsung-specific element usually runs under $40.
Why did my Samsung oven stop heating right after the self-clean cycle?
Self-clean is rough on everything. The oven runs at 900 degrees plus for a few hours and it stresses every component in there. The thermal fuse is the first thing I check after a failed self-clean because that sustained heat can trip it permanently. It's cheap, like $10, and it's almost always the culprit in this specific scenario. The igniter on gas models can also weaken or die from the extended heat. If your oven died right after self-clean, start with the thermal fuse before you do anything else.
How long does a Samsung oven bake element usually last?
Typically 5-10 years depending on how hard you use it. Running self-clean frequently shortens that lifespan noticeably. I've seen elements go in 4 years on ovens where the owner ran self-clean every month, and I've seen them last 15 years on units that barely got used. The element itself is a cheap part so when it goes, just replace it and move on.
