A Samsung oven turning on by itself is a known safety issue that should be taken seriously and is usually caused by a faulty control board, touchpad short, or knob design. For electric slide-in models, the front control knobs can be accidentally bumped by pets, children, or even your hip, turning on a burner, which led to a recall for some models. For the oven itself turning on without input, the most common cause is a failing main control PCB or membrane touchpad that develops a short and sends a false signal to the bake element, often after high heat or self-clean cycles that overheat electronics. Moisture or grease getting into the control panel can also cause a short. Software glitches in SmartThings-connected ovens can trigger remote start if the app malfunctions. If your Samsung oven turns on by itself, you should immediately turn it off, unplug it or turn off the breaker, and do not leave it unattended. Contact Samsung support and report it to the CPSC, check if your model is under recall, and request a control board replacement. Do not use self-clean until it is inspected, as this can worsen board failure.
