Samsung Chef Series Induction slide in range, model NE58H9970WS/AA. Oven intermittently overheats. Began summer 2022. This happens suddenly and rapidly scorching whatever is in the oven. Hot enough I fear a fire. Opening the door releases enough heat to set off smoke detectors.


Twice the oven has come on by itself - I had been in the kitchen so may have inadvertently activated the control panel in some way - and I discovered the overheating because the cook top was very hot to the touch. Now the control panel has gone blank, no light in the oven, no accesses to any features controlled by the control panel. Burners are unaffected.

You can first ohm test the oven temperature sensor using a multimeter. You should measure between 1050 to 1100 ohms of resistance at room temperature. Replace the oven temperature sensor if resistance is off by more than 200 ohms. If the oven sensor ohm test is good, then the main control board is the culprit.

You will need to pull the range out from the wall then UNPLUG IT, then remove the back access panel then you will see the connector that goes to the oven sensor, it just unsnaps and pulls off.

Sometimes you can get lucky, and by taking the screws out from inside the oven where the oven sensor mounts, you may be able to pull the oven sensor wire through the hole and test it without pulling the range out from the wall.

Here's the oven sensor for your model:

Take a photo of your model number tag if you could please, we need to see if your model has a revision number, in case you need to order the main control board.

Thanks, Jake. An appliance repair person has already replaced the Thermister (looks just like the pix you gave) and he said the control board was likely the next step if that did not fix it. Since then, the repair person has become injured and cannot take on the project. Thanks for offering to obtain the part number for the control board.

Ok, then yes you'd need a new controller board.

Here's the controller board for your model:

Make sure you unplug the range before replacing it.

Here's another thread with the service manual in post #1 that shows you how to replace it:

FIXED - Samsung NE58H9970WS/AA Induction Range not controlling oven temperature

The oven temperature control is not working on our Samsung slide-in induction range. Normally we do not have the oven divider in. In this mode, neither Chef Bake or Convection Bake (Bake) work. In both Bake and Chef Bake, the oven will heat to the set temperature, then fail to hold the...
