Oven is completely cold
The display works, but the cavity never warms and food stays raw.
Start here: Start with settings, clock, door closure, and power. Then split gas versus electric.
Oven heating problem
Samsung Oven Not Heating
Direct answer: A Samsung oven that will not heat is usually dealing with one of three things: the wrong mode or a power issue, a failed oven igniter on a gas model, or a failed oven heating element or oven sensor on an electric model.
Most likely: Start by confirming the oven is actually in Bake, the door is fully closed, and the clock is set. After that, the most common real failures are a weak oven igniter on gas models and a burned oven bake element on electric models.
Separate the symptom first. Dead cold is different from slow heating, and bake-only trouble is different from both bake and broil failing. Reality check: most no-heat calls end up being a basic setting issue or one obvious failed heating part, not a mystery. Common wrong move: replacing parts before checking whether the oven has full power or whether the igniter actually glows.
Don’t start with: Do not start by ordering an oven control board. Controls do fail, but they are not the first bet when the oven is dead cold or only partly heating.
Dead cold oven?Check the mode, clock, door closure, and house power before opening anything.
Heats weakly or unevenly?Look for a glowing-but-not-lighting igniter, a visibly damaged bake element, or a sensor problem.

What kind of no-heat problem you actually have
Bake does not heat but broil does
The oven may brown from the top in broil, but bake will not come up to temperature.
Start here: On electric models, suspect the oven bake element first. On gas models, suspect the oven igniter for bake.
Takes a long time to heat or never reaches set temperature
The oven gets warm eventually, but preheat drags on and cooking is off.
Start here: Look for a weak gas oven igniter, a partially failed oven bake element, or a drifting oven sensor.
Only part of the oven seems to heat
You may see top heat only, bottom heat only, or uneven browning with long cook times.
Start here: Check whether one heating source is missing, then inspect the matching element or igniter path.
Most likely causes
1. Wrong mode, delayed start, or clock/setup issue
These ovens can look normal on the display while never actually starting a heat cycle.
Quick check: Cancel the cycle, set the clock if it is flashing, choose Bake, set a temperature, and listen for the oven to start.
2. Lost power on one leg or tripped breaker
An electric oven can still light up and seem alive while the heating circuit is missing full power.
Quick check: Check the breaker for a partial trip and reset it once fully off, then back on.
3. Weak gas oven igniter or failed electric oven bake element
These are the most common hardware failures when the oven will not heat or heats very slowly.
Quick check: Gas: look for an igniter that glows but never lights the burner. Electric: look for blistering, cracks, or a burned spot on the bake element.
4. Out-of-range oven sensor
A bad sensor can make the oven underheat, overcorrect, or stop heating properly even when the rest of the oven seems normal.
Quick check: If both bake and broil act odd without visible element damage, the sensor moves up the list.
Step-by-step fix
Step 1: Reset the basics before chasing parts
A surprising number of no-heat complaints come down to the oven not actually being told to heat, or being stuck in a delayed or interrupted state.
- Press Cancel or Clear to stop any old cycle.
- Make sure the clock is set if the display is flashing or recently lost power.
- Select Bake, not Timer, Keep Warm, or Delay Start.
- Set a normal cooking temperature like 350 degrees and wait a full minute.
- Confirm the oven door is fully closed and not bouncing back on the latch or gasket.
Next move: If the oven starts heating now, the problem was setup or cycle selection, not a failed part. If the display accepts the command but the oven stays cold, move to power and heat-source checks.
What to conclude: You have ruled out the easy false alarms first, which keeps you from buying parts for a control problem that is not really there.
Stop if:
- The display is dead or badly flickering.
- You smell gas.
- The door will not close or latch normally.
Step 2: Check for a power problem before opening the oven
Electric ovens often lose heating because of a breaker issue or missing full voltage, while the display still works and fools people into thinking power is fine.
- Go to the electrical panel and find the oven or range breaker.
- If it looks tripped or half-tripped, switch it fully off, then back on once.
- Return to the oven and start Bake again.
- If you have a gas oven, still check that the outlet or circuit is on, because the igniter and controls need power too.
Next move: If the oven heats after the breaker reset, watch it through a full preheat. A repeat trip points to a deeper electrical problem that needs service. If the breaker is fine and the oven still will not heat, the failure is likely inside the oven.
What to conclude: You have separated a house power issue from an oven component issue.
Step 3: Split the diagnosis: gas oven or electric oven
The next likely part depends completely on how the oven makes heat. Gas models usually fail at the igniter. Electric models usually fail at the bake element first.
- Start a Bake cycle and watch through the bottom vent or access area if your model allows a safe view.
- For a gas oven, listen for gas ignition after the igniter starts glowing.
- For an electric oven, look for the lower oven bake element heating evenly from end to end.
- Then try Broil and compare what works and what does not.
Next move: If one mode heats and the other does not, you have narrowed it to the bake side or broil side instead of the whole oven. If neither bake nor broil heats, keep going and consider the sensor or a control issue after the common parts are ruled out.
Step 4: Confirm the common failed part on your oven type
This is where the usual no-heat parts show themselves with physical clues instead of guesswork.
- On a gas oven, watch the oven igniter during Bake. If it glows for a while but the burner never lights, or lights late with very slow preheat, the oven igniter is the likely failure.
- On an electric oven, inspect the oven bake element for splits, blistering, rough burned spots, or a section that never glows.
- If Bake fails but Broil works normally, the oven bake element or bake igniter becomes the main suspect.
- If both Bake and Broil are weak or erratic and no element damage is visible, the oven sensor becomes more likely.
Next move: If you found a glowing-but-not-lighting gas igniter or a visibly damaged electric bake element, you have a solid repair path. If there are no clear clues and both heating modes are affected, stop short of buying random parts and focus on sensor testing or professional diagnosis.
Step 5: Replace the confirmed part or call for service on the control side
Once the symptom matches a common failed part, replacing that part is reasonable. If it does not, the remaining possibilities are less DIY-friendly and more expensive to guess at.
- Replace the oven igniter if your gas oven igniter glows but does not light the burner promptly, or preheat is extremely slow.
- Replace the oven bake element if it is visibly damaged or Bake is dead while Broil still works on an electric oven.
- Replace the oven sensor if heating is consistently off in both modes and the common heat source parts check out.
- If neither mode heats and no common part is clearly bad, schedule service for wiring or oven control diagnosis rather than guessing.
A good result: If the oven reaches set temperature normally and cycles on and off as expected, the repair path was correct.
If not: If the new part does not restore heat, stop and have the oven professionally diagnosed for wiring or control failure.
What to conclude: You either finish the repair with a supported part, or you avoid sinking money into a control guess with weak evidence.

FAQ
Why does my Samsung oven turn on but not heat?
The display and lights can work even when the oven is not actually heating. The usual reasons are the wrong mode, a clock or delay setting, a partial power problem on an electric oven, a weak oven igniter on a gas oven, or a failed oven bake element.
How do I know if my oven igniter is bad?
On a gas oven, a bad oven igniter often still glows. The giveaway is that the burner does not light, lights very late, or the oven takes a long time to preheat. Glow alone does not mean the igniter is strong enough.
Can an electric oven have power but still not heat?
Yes. An electric oven can appear normal at the display while missing full heating power because of a tripped breaker or supply issue. That is why checking the breaker early matters.
If broil works, is the bake element bad?
Often, yes on an electric oven. If Broil heats normally but Bake does not, the oven bake element is one of the first things to inspect. On a gas oven, the bake-side oven igniter is the more common failure.
Should I replace the oven control board if my oven is not heating?
Not first. Control boards are usually farther down the list than settings, power, the oven igniter, the oven bake element, or the oven sensor. Guessing at a control board gets expensive fast.
Can a bad oven door gasket keep the oven from heating?
Usually it will not make the oven completely dead cold, but it can cause long preheat times, weak baking performance, and heat leaking from the door area. It is worth checking if the oven heats some but not well.
