Most modern residential kitchen ovens are equipped with an automatic safety shut-off feature—often called Sabbath mode or an automatic energy-saving timeout—that shuts the heating elements off after 12 consecutive hours of continuous operation at 400 degrees Fahrenheit. However, mechanically, a healthy electric or gas oven can technically run indefinitely as long as adequate ventilation is maintained and fuel or electrical supplies remain uninterrupted. You can troubleshoot continuous operation safety by checking your user manual for safety settings. You can verify that your oven is operating within safe parameters when monitoring internal component temperatures confirms that prolonged baking cycles do not overheat surrounding cabinetry.
