The difference between 30 seconds and a minute can be quite large when using a microwave. So the interior lighting feature is useful for knowing the condition of the food while it's cooking and for alerting you if the dish is about to boil. Do you want to see how the cooking process goes but don't want to open the oven door and lose the heat from the inside? Halogen Illumination helps you clearly see what's inside the oven, so you can take control of your creativity in the kitchen while keeping the oven door firmly closed. It's easy for a flame to go out when you're not around, allowing dangerous gas to escape into your home. The Gas Safety feature will detect that the oven eye burner has gone out due to a cooker or air boiling, and will automatically turn off the gas supply. No leaking after today and no worries.
