Samsung Convection Oven Fan Not Turning Off? (Here’s WHY!)

Samsung Convection Oven Fan Not Turning Off

Picture this, it’s been hours since you’ve baked a fresh batch of chocolate chip cookies and yet you can still hear the whirring sound coming from your oven. You check and see that it’s the cooling fan at the very back. 

At first, you may think it’s normal because the oven needs to cool down too. But then you notice that it does not shut off at all!

What do you do if this happens and what does this mean for your oven?

Fear not! Because we have listed the reasons behind this problem, what to do, and when you should call a professional!

Is the fan supposed to stay on in a Samsung convection oven?

The convection fan in a Samsung oven should not stay on for longer than an hour after use. It should only stay on to help cool the oven for at most an hour. 

If the oven fan stays on for longer than that, it could indicate something wrong with the oven.

Why does my Samsung oven fan stay on?

The convection fan in a Samsung oven stays on to cool the appliance down after use. But if it runs for more than an hour,  there may be a defect in the thermostat or a problem with the control board. 

The fan itself is most likely not broken, rather there could be a problem with the thermostat or control board that makes the fan run longer than it should.

How to Fix a Samsung Oven Fan That Won’t Turn Off

One easy solution to shut off the cooling fan in your Samsung oven is to turn it off manually on the control panel.

If the oven fan runs longer than needed to cool down the appliance, check the oven’s thermostat or control board as they may be defective and need to be replaced. 

Listed below are ways to determine the cause of this issue and what steps you can take to repair this.

Oven Not Turned Off• Turn the oven off. 
Defective Thermostat• Test the thermostat using a multimeter to check if there is electricity flowing through the thermostat at room temperature. 

• If there isn’t, this indicates that the thermostat is defective and needs to be replaced by a professional. 
Damaged Oven Control Board• Try pressing the off button on the control board. 

• If the fan still runs after pressing the button, this indicates a problem with the control board. To fix the issue, it needs to be replaced.

Oven Not Turned Off

The fan on a Samsung oven is meant to run for at most an hour after the oven is used. But if your fan does not automatically shut off after cooling down the appliance, you can manually turn this feature off. 

Oven Not Turned Off

Solution: Turn off the oven fan by pressing the off button on the control panel. Make sure that the oven has cooled down to room temperature before doing these steps.

  • Step 1: Locate the on/off button on the control panel on the convection oven. 
  • Step 2: Press and hold the off button until you can no longer hear the fan whirring.

If the fan doesn’t turn, then the repair worked, but if it still doesn’t shut off then there could be a bigger problem in your oven.

Important Note: 
• Replacing defective parts of the oven should be done under the supervision of a trained professional. 

Defective Thermostat

A faulty thermostat may cause the fan to run longer than it should. This component controls the temperature of the oven, and if it malfunctions, the oven may get too hot, forcing the fan to activate. 

As the oven heats up, the fan thermostat sends voltage to the oven fan. A defective thermostat may continue to power the fan even after the oven has cooled down completely.

You can use a multimeter to test the thermostat for continuity, which is a continuous electrical path present in the thermostat. At room temperature, the thermostat should test negative for continuity — meaning no current is running through the part. 

Defective Thermostat

The component may be defective if the thermostat reads positive for continuity at room temperature and will need to be replaced. 

Solution: If you suspect a broken thermostat is causing your oven fan to stay on, use a multimeter to check for continuity. 

  • Step 1: Make sure the oven is turned off and has cooled completely to room temperature before accessing the thermostat through the back panel of the appliance.

  • Step 2: Once you have accessed the thermostat, connect the black reader lead of your multimeter to one of the convection fan motors terminals and the red lead to the other terminal. 

Because the oven is turned off, the multimeter should read zero or negative. If it shows that there is continuity then make sure that you have a replacement thermostat ready. 

  • Step 3: Unscrew the defective thermostat from the oven. 
  • Step 4: Screw the new thermostat in place.

It is recommended to contact a professional technician for assistance. Do not attempt to replace the thermostat by yourself if you have no technical experience. 

Damaged Oven Control Board

One possible cause of an oven fan not turning off is a faulty oven control board. This component controls all of your oven’s activities, including the fan.

Relays on the oven control board manage power to the bake, broil, and fan circuits. Thus, the fan may run longer if the control board is not operating properly

Damaged Oven Control Board

If one of these relay shorts close, the control board may send continuous voltage to the oven fan. You can tell that it is defective when you press the off button and it does not turn off. 

Solution: If the oven fan is not turning off due to a defective oven control board, an expert oven repair technician should be contacted to inspect and repair the oven control board.

To check if the oven control board is defective:

  • Step 1: Locate the oven control board found directly behind the control panel.
  • Step 2: Using a screwdriver, remove one or more access panels to reach the board. 
  • Step 3: Inspect the control board for burning or a short-circuited component.

You can also use a multimeter to confirm the board is receiving power.

  • Step 4: Before testing the board with a multimeter, make sure the oven is plugged in as we are going to test for active current. 
  • Step 5: Using the oven’s wiring diagram found in its user manual, determine the location of the board’s power input connector and wires. 
  • Step 6: set the multimeter’s main selection dial to volts AC. 
  • Step 7: Connect the black and red meter leads to the board’s input terminals. The leader displays should indicate close to 120 volts reaching the board.

 If the board is receiving the proper voltage but is not sending power to the other components, the control board is faulty and will be to be replaced by a professional. 

And there you have it! 

If the cooling fan in your Samsung oven doesn’t turn off hours after its use, you don’t have to panic. There’s no need to replace the oven. 

Hopefully, this article has helped in pinpointing the problem and identifying which parts of your Samsung oven need to be addressed.
