Whether an electric oven turns back on automatically after a power outage depends on the specific model and its features. Some electric ovens have a built-in memory function that allows them to resume their previous settings after a power interruption. In such cases, the oven will typically restore power and continue operating once the power is restored.
However, not all electric ovens have this feature. Basic models without memory functions will require manual intervention to turn them back on after a power outage. In such cases, you would need to reset the oven and select the desired settings again before it can be used.
To determine the exact behavior of a specific electric oven model, it is recommended to refer to the manufacturer's instructions or contact their customer support for accurate information.
