What is the purpose of a draft inducer motor in a gas furnace?

The purpose of a draft inducer motor in a gas furnace is to ensure proper draft and venting of exhaust gases. This component plays a crucial role in maintaining a safe and effective operation of the furnace by drawing combustion gases out of the heat exchanger and expelling them through the venting system.

By creating a negative pressure in the furnace, the draft inducer motor helps to push hazardous exhaust gases, such as carbon monoxide, outside of the home, thus preventing a buildup of these gases indoors. This is essential for the safe operation of the furnace and contributes to overall indoor air quality. Additionally, the draft inducer ensures that there is adequate airflow for combustion, which is vital for the furnace to operate efficiently and prevent any potential issues such as backdrafting, where exhaust gases could flow back into the living spaces.

In summary, the draft inducer motor is fundamental for the proper venting of exhaust gases, ensuring that the furnace operates safely and effectively.
