The A155 Furnace Inducer Motor is an integral component of your furnace's combustion system. When the thermostat calls for heat, the inducer motor activates first, drawing combustion air into the burner and expelling exhaust gases. This creates a negative pressure within the heat exchanger, allowing the pressure switch to close and signal the ignition sequence to begin. The motor continues to operate throughout the heating cycle to ensure proper ventilation of combustion byproducts.
