Fan keeps running but heat seems gone
You hear airflow from the oven vent, but the cavity is cooling down and no element is glowing.
Start here: This is often normal cooling-fan operation. Let the oven cool fully before chasing parts.
Direct answer: If a Samsung oven will not turn off, the first thing to figure out is whether it is still making heat or only running the cooling fan. A fan can run for a while after cooking and be normal. Actual heat that will not shut off points more toward a stuck oven control relay, a keypad command issue, or a control that did not cancel the cycle.
Most likely: Most often, homeowners are seeing one of two things: the oven is in a timed mode or delayed cycle and did not fully cancel, or the oven cooling fan is still running after the heat stopped. If the cavity is still getting hotter with the controls set to off, the control is the stronger suspect.
Start with the simple checks you can see and hear. Put a hand near the vent, look through the door for glow, and watch the display. Reality check: a cooling fan can run well after cooking and still be normal. Common wrong move: killing power, turning it back on, and assuming the problem is fixed without checking whether the oven starts heating again on its own.
Don’t start with: Do not start by ordering a new control board just because the display is lit or the fan is running. First confirm whether the oven is actually heating, whether the broil or bake element is glowing, and whether a hard power reset changes the behavior.

The cavity keeps getting hotter, food keeps cooking, or you can see a bake or broil element still glowing.
Start here: Treat this as the more serious branch. Shut power off and focus on control failure or a command that did not cancel.
The panel may be blank or idle, but you still feel strong heat or see an element glowing.
Start here: That points away from a simple setting issue and more toward a stuck oven control relay.
The oven seems stuck on, locked, or keeps running much longer than usual after a very hot cycle.
Start here: Separate normal cooldown from a true heat-stuck condition. Self-clean can keep fans running a long time, but it should not keep active heating going indefinitely.
Many ovens keep the cooling fan running after cooking, especially after high heat or self-clean. You will hear airflow, but the oven cavity should slowly cool instead of getting hotter.
Quick check: Press off, wait a few minutes, and check whether you feel only vent air with no rising cavity heat and no glowing element.
A delayed bake, timer-related setting, or partially accepted keypad command can make the oven look off when it is still following a cooking command.
Quick check: Check the display for bake, broil, timer, delay, cook time, or lock indicators, then press cancel/off firmly once or twice.
If the oven keeps heating even with the controls set to off, the relay on the oven control can weld closed and keep sending power to a heating circuit.
Quick check: With the oven supposedly off, look for a glowing element or confirm that the cavity temperature keeps climbing instead of dropping.
A keypad that is sending bad commands can restart a cycle, ignore off commands, or act like a button is being held.
Quick check: Watch for unresponsive buttons, random beeps, repeated mode changes, or a display that does not respond cleanly when you press cancel.
This separates a normal fan-run condition from a real shutoff failure before you get into parts or power resets.
Next move: If the oven is cooling down and only the fan is running, let it finish its cooldown cycle. That is usually normal. If the oven is still making heat, getting hotter, or an element stays on, move to the next step right away and cut power if needed.
What to conclude: A fan by itself is usually not the problem. Ongoing heat with the oven set to off is the problem you need to chase.
A surprising number of ovens that 'won't turn off' are still in a delayed, timed, or locked mode rather than having a failed part.
Next move: If the display clears and the oven stops heating, watch it through one full cool-down to make sure it does not restart on its own. If the panel ignores off commands, acts erratic, or the oven keeps heating anyway, continue to a full power reset.
What to conclude: A clean cancel that stops the heat points to a settings or keypad issue. Heat that continues anyway points more toward the control itself.
A control can latch up after a power glitch, long bake, or self-clean cycle. A real reset is worth trying before you assume a failed control.
Next move: If the oven stays idle after power is restored and later shuts off normally during a test bake, the issue may have been a temporary control glitch. If it resumes heating on its own, or the same shutoff problem returns quickly, the control or keypad branch is much stronger.
You want one solid clue, not a guess. This keeps you from buying the wrong part.
Next move: If the oven now starts and stops normally, keep using it cautiously and monitor it over the next few cooking cycles. If it repeats the problem, stop using the oven until the failed control side is repaired.
By this point you should know whether you have a normal fan cooldown, a control problem, or a safety issue that should not stay in service.
A good result: If the oven now shuts off normally and only cools with the fan, you can return it to service and keep an eye on it.
If not: If it still cannot be trusted to shut off, keep power off and do not use the oven until repaired.
What to conclude: An oven that cannot reliably stop heating is not a nuisance issue. It is a control failure until proven otherwise.

That is often normal. The oven cooling fan can keep running after cooking, especially after high heat or self-clean, to protect the controls and cabinet area. If the oven cavity is cooling down and no element is glowing, the fan alone is usually not a fault.
Check for actual heat, not just airflow. If the temperature inside keeps rising, food keeps cooking, or you can see a bake or broil element glowing, the oven is still on. If you only hear the fan and the cavity is cooling, it is likely in cooldown.
Usually no. A heating element can fail open or short physically, but an oven that keeps powering the element after you press off more often points back to the oven control relay or control system.
Sometimes a full power reset clears a control glitch, especially after a long bake or self-clean cycle. If the oven starts heating again on its own or repeats the problem soon after, the reset did not solve the real issue.
Only if you are sure it was normal cooldown and not active heating. If the oven has ever kept heating with the controls off, restarted by itself, or ignored off commands, stop using it until the control problem is repaired.
Go by the clues. If the oven keeps heating with the display showing off or idle, the oven control board is the stronger suspect. If buttons are erratic, unresponsive, or trigger the wrong modes, the touchpad or interface side moves up the list. On some ovens those parts are combined, so fitment matters.
