It is generally safe to leave your house with an electric stove turned off but still plugged in. Electric stoves are designed to be left plugged in when not in use. When the stove's knobs or controls are turned off, the electrical circuit that supplies power to the stove is effectively cut off, and there is no current flowing through the stove's heating elements.
However, if you prefer an extra layer of caution or want to conserve energy, you can unplug the stove when not in use. Unplugging the stove ensures that there is no possibility of accidental activation or any potential electrical issues while you are away. Additionally, it can save a small amount of standby power consumption, which can add up over time.
Whether you choose to leave it plugged in or unplug it is a personal preference. If you decide to unplug the stove, it's essential to make it a habit to check that the stove is indeed unplugged before leaving the house to avoid any unintended inconvenience or risks.
