If your Samsung oven turns off by itself, the most likely cause is a failing touchpad, especially if some buttons respond intermittently or not at all. Replace the touchpad when the controls are unreliable. A blown thermal fuse is another possibility if the oven overheated. Test the thermal fuse with a multimeter for continuity, and replace it if it is open because it cannot be reset. If only some controls work, the touchpad and control panel may be defective; if no buttons work, suspect the control board instead. An incoming power problem can also make the oven keep turning off, so check whether the circuit breaker has tripped. Less commonly, loose or burned connections, a failed relay, or another fault in the control board or main control board can interrupt power. If your oven shuts off while baking and you are asking, "Why does my oven keep turning off?" check these parts in this order. Enter your Samsung oven model number to find the exact replacement part for your appliance.
01 - Samsung Range/Stove/Oven Touchpad
If the oven turns off on its own, determine if some of the buttons on the touchpad respond intermittently or not at all. If so, it's likely the touchpad is faulty and should be replaced.

If the oven gets too hot, the thermal fuse trips to shut off power to the oven. If the thermal fuse has blown, the oven will not heat. However, this is not a common occurrence. To determine if the thermal fuse is at fault, use a multimeter to test the fuse for continuity. If the thermal fuse does not have continuity, replace it. The thermal fuse cannot be reset—if the fuse has blown, it must be replaced.
03 - Samsung Range/Stove/Oven Touchpad and Control Panel
If an oven won't turn on, it's possible the touchpad and control panel is defective. One way to help confirm this is to determine if some touchpad buttons respond while others don't. If some of the buttons still work, then it's quite probable the touchpad and control panel is faulty and requires replacement (if none of the buttons work, a defective control board is more likely the cause of the oven not turning on).
If an oven turns off on its own there could be an incoming power problem. Verify the circuit breaker hasn't tripped.

05 - Samsung Range/Stove/Oven Control Board
The board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.
The main control board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.
