Understanding the Purpose of a Convection Fan

Before we dive into the potential issues that may cause your stove’s convection fan to malfunction, let’s first understand the purpose of a convection fan in a stove. A convection fan helps circulate hot air inside the oven, ensuring even heat distribution and more efficient cooking.

While traditional ovens rely on radiation to cook food, convection ovens use a fan to circulate the hot air, allowing the food to cook more evenly and quickly. This process can significantly reduce cooking time and improve the overall quality of your dishes.

Convection fans work by transferring heat energy from the heating element to the food through a process called convection. Heat flows from the heating element to the air inside the oven, which then circulates around the food and transfers heat energy to the food’s surface, cooking it from all sides.

Compared to traditional ovens, convection ovens can achieve a more uniform temperature throughout the cooking process, and as a result, require lower cooking temperatures or shorter cooking times, ultimately saving time and energy.

Now that we understand the purpose of a convection fan let’s explore why it may not be performing its function as expected.
