Samsung Oven Turning On By Itself? Why + Fixes

Samsung ovens typically turn on only when the user presses the power start button/option. If your samsung oven turns on itself, this is a sign of a fault in the central unit. This is a rare issue but should be fixed soon.

This issue can occur when the main control board is faulty, the power switch fails or debris/moisture builds up in the control panel. You will need to inspect these internal parts of your oven to fix the actual source of the problem.

Fixing this issue requires technical knowledge, repair tools, and experience. Let’s understand the causes in-depth and ways to fix the oven that’s turning on by itself.

Samsung Oven Turning On By Itself?

Reasons Samsung oven turning on by itself?

You will need to check two things in your oven if your oven is turning on by itself. First is a faulty control board and moisture on it. Let’s discuss these causes in depth.

  1. Faulty Control Board: 

One potential cause of your Samsung oven turning on by itself is a defective control board. This is the main control board which is located behind the control panel. 

Technically, The control board serves as the command center of the oven. This element is responsible for coordinating its various functions. If the control board malfunctions, it may send erroneous signals. 

Wrong signals can result in the oven activating without any user input. Replacing the faulty control board with a new one can rectify this problem. You will need to remove the control panel board first to access the main control board.

  1. Debris or Moisture in the Control Panel: 

Another possible cause of spontaneous activation is the accumulation of debris or moisture in the control panel. 

Over time, food particles, dust, and moisture can find their way into the control panel. When this occurs, this leads to button sticking or trigger malfunctions. 

It is crucial to inspect and clean the control panel thoroughly, using a soft cloth and mild detergent. Ensure that no residue or moisture remains. 

Additionally, check for any signs of water damage or leaks near the oven.

  1. After the waiting period, flip the breaker switch back to the “on” position. This will restore power to the oven.
  1. Test the oven to see if the issue of it turning on by itself has been resolved once the power is restored. Monitor its behavior for a period of time to ensure it remains off until intentionally activated.


If you encounter the problem of your Samsung oven turning on by itself, it is crucial to address it promptly. This unusual occurrence indicates a fault in the central unit, such as a faulty control board or the presence of debris/moisture in the control panel. 

Seeking professional assistance from a qualified technician is highly recommended to diagnose and fix the issue accurately. Alternatively, you can try resetting the oven as a temporary solution.
