can the oven work without the fan?

Hi there! Based on your question, the Defy Slimline 600 MSE Convection Oven would work without the fan. While convection ovens cook more quickly and evenly with the fan circulating hot air, the Defy oven has heating elements that will bake and roast your foods without fan assistance. Two other great option if you prefer not to use convection are the Russell Hobbs Air Fryer Oven and Sunbeam Professional Convection Oven. The Air Fryer Oven lets you air fry, bake, roast and grill without super hot air being blasted around. And the Sunbeam oven has customizable settings so you can control the fan and temperature separately. Hope this helps in your search for the right oven! Let me know if you need any other details.
