What is the main purpose of a fan in a gas furnace?

To ignite the gas
To reduce noise
To circulate air
To control temperature

The correct answer is: To circulate air

The main purpose of a fan in a gas furnace is to circulate air. When the gas in the furnace is ignited and heats up, the fan distributes the warm air throughout the space being heated. This helps maintain a consistent and comfortable temperature in the area. While reducing noise and controlling temperature are also important functions in a gas furnace, the primary role of the fan is to circulate the heated air.
