Abstract
A furnace includes a main blower housed in an inlet plenum that circulates temperature controlled air through the furnace and an inducer fan that circulates combustion gases through the furnace. The inducer fan is driven by an inducer fan motor with a housing that defines a hollow interior and surrounds the motor. The inducer fan motor housing is in communication with the inlet plenum and operation of the main blower draws cooling air through the interior of the motor housing to cool the motor.
