How Does An Electric Oven Regulate Temperature

An electric oven regulates temperature using the thermostat. As the oven heats up, the thermostat monitors the temperature. When the right temperature is reached, the thermostat switches the oven off. Once the oven’s temperature reduces a bit, the thermostat turns the oven on again. This happens throughout the cooking process to ensure your meal is cooked at the right temperature.
