What does a thermo fan do in oven?

A thermo fan in an oven circulates hot air around the oven cavity, ensuring even cooking and preventing hot spots. It helps distribute heat more evenly, resulting in food that is cooked more consistently. The fan also helps reduce cooking times by circulating the hot air more efficiently, allowing food to cook faster. Additionally, the thermo fan can help reduce energy consumption by distributing heat more efficiently, which can save money on electricity or gas bills.
