7. Operation
The draft inducer blower motor is a critical component in your furnace's combustion system. Its primary function is to draw combustion gases from the heat exchanger and expel them through the exhaust vent. This creates a negative pressure within the combustion chamber, allowing fresh air to be drawn in for proper fuel ignition and efficient burning. The motor operates automatically when the furnace calls for heat, ensuring safe and effective removal of exhaust byproducts.
