No Draft Inducer Blower, No Heat
A draft inducer blower is the fan that you hear churning 30-60 seconds before your furnace booms to life. Its main functions are to clear the heat exchanger of gas leftover from the previous cycle, move air through the blower housing and keep burners from getting clogged with soot.
Bottom line – if your draft inducer blower is not working, your furnace cannot create heat.
