Direct answer: A range oven fan that runs all the time is often either doing a normal post-cook cool-down or reacting to a control that still thinks the oven is hot. Start by separating a short cool-down from a fan that never stops, then check for active settings, a stuck keypad or knob, and overheating clues before you think about parts.
Most likely: The most common real problem is not the fan itself. It is usually a control issue, a bad oven temperature reading, or an oven that got too hot and is trying to protect itself.
If the fan shuts off after the oven cools down, that is usually normal. If it runs for hours, comes on with a cold oven, or starts right after a self-clean cycle and never quits, you need to check whether the oven is actually hot, being told it is hot, or has a stuck control signal. Reality check: some ovens run the cooling fan much longer than people expect. Common wrong move: killing power over and over without checking whether a bake, broil, timer, or self-clean mode is still active.
Don’t start with: Do not start by ordering a control board or pulling the range apart while it is still hot. Many ovens keep the cooling fan on for a while by design.
You turn the oven off, hear a steady fan, and it finally shuts down after the cabinet cools.
Start here: This is often normal. First confirm there is no active bake, broil, warm, or self-clean setting still showing.
The fan keeps going long after the oven cavity and control area feel cool.
Start here: Check whether the display still shows a cooking mode, error, or locked/self-clean status before moving to sensor or control checks.
The fan starts at power-up or stays on even though the oven has not been used recently.
Start here: Look for a stuck keypad, stuck selector, or a control that is falsely reading heat.
The fan may be loud, constant, or paired with a hot control panel area after a self-clean cycle.
Start here: Treat this as an overheating or control problem first. Let the oven cool fully, then check door lock status, error codes, and whether the fan still runs on a cold start.
Many ranges run a cooling fan after the oven is turned off to protect the control area and wiring from stored heat.
Quick check: With the oven off, wait until the cavity, door glass, and control panel feel cool. If the fan shuts off on its own, it was likely normal operation.
A range can keep the fan running if bake, broil, warm, convection, or self-clean did not fully cancel, even if the heat elements or burner are off.
Quick check: Look closely at the display and indicator lights. Cancel the cycle, clear the timer, and make sure the door is not still in a locked-clean state.
If the control thinks the oven is still hot, it may keep the cooling fan on long after the oven has cooled.
Quick check: When the oven is stone cold, see whether the display shows an error, acts like preheat is already underway, or behaves oddly after a power reset.
A control board or keypad fault can keep sending fan power or keep the oven in a phantom heat-protection mode.
Quick check: If the fan starts immediately when power is restored to a cold oven and no mode is selected, the control side becomes much more likely.
You do not want to chase a fault when the oven is simply shedding heat the way it was designed to.
Next move: If the fan shuts off once the oven cools, you likely do not have a repair issue. If the fan keeps running long after the oven is cool, move on to control and sensor checks.
What to conclude: A fan that stops after cool-down is usually normal. A fan that runs with a cool oven is usually being told to run by a control or false temperature signal.
A half-canceled bake cycle, warm mode, convection setting, or self-clean lock can make the fan look stuck when it is not.
Next move: If the fan stops after the mode clears, the issue was an active setting or stuck clean status, not a failed part. If the display is blank or normal but the fan still runs, keep going.
What to conclude: This points away from simple user-setting issues and more toward a false heat reading or a control fault.
A reset can clear a confused control, and the fan behavior right after power returns tells you a lot.
Next move: If the reset restores normal behavior, keep using the range but watch for the problem returning. If the fan starts immediately on a cold oven after power is restored, the control or temperature-sensing side is the stronger suspect.
An oven that truly overheated, or a sensor that falsely reports high heat, can keep the cooling fan running as a protective response.
Next move: If you find clear overheating symptoms or a damaged sensor probe, the oven temperature sensor is a supported repair path. If the sensor looks normal and cooking performance has been normal, a stuck control relay or keypad fault is more likely.
By now you should know whether this was normal cool-down, a stuck mode, a likely sensor issue, or a control problem that needs careful escalation.
A good result: A successful sensor repair should restore normal fan shutoff timing. A control repair should stop cold-start fan run-on and other phantom oven behavior.
If not: If a new sensor does not change the symptom, or if the oven shows multiple strange behaviors, professional diagnosis is the right next move.
What to conclude: You are down to the two most credible repair paths: bad temperature feedback or a failed control circuit.

Yes. Many ranges run a cooling fan after baking or broiling to protect the controls and surrounding parts from stored heat. If it shuts off after the oven cools, that is usually normal.
It varies by model and how hot the oven got. A short run after cooking can be normal. If it runs for hours with a cold oven, that is no longer normal behavior.
Self-clean puts extreme heat into the oven and control area. That can leave the oven in a stuck clean or lock state, stress the temperature sensor, or damage the control so it keeps the fan on.
Yes. If the sensor tells the control the oven is still hot when it is actually cool, the control may keep the cooling fan running as a protective response.
If the oven otherwise works normally and the fan is the only symptom, you can sometimes use it cautiously for a short time. But if the oven overheats, shows errors, smells hot, or the fan runs on a cold start every time, leave it off until you fix it or have it serviced.
