Westinghouse 904858 Gas Furnace Blower Motor 1/2 Hp 115V

Product Description

The WESTINGHOUSE 904858 is a blower motor designed for use in condensing and non-condensing gas furnaces. Rated at 1/2 HP and 115 volts with four speed settings, this motor drives the air handler blower wheel to circulate conditioned air through the duct system. It is a direct replacement component intended for installation by licensed HVAC technicians during scheduled maintenance or motor failure service calls. The four-speed configuration allows the motor to support variable airflow demands across heating and cooling modes where the furnace is paired with a cooling coil.

This blower motor is specified for residential gas furnace applications, both condensing and non-condensing configurations. It fits into the blower compartment of the furnace cabinet and connects to the existing blower wheel assembly. Compatible models include the 072-24B, 090-24B, 054D-24B, and 072D-24B furnace units. Installations typically occur during motor burnout replacement or preventive maintenance on older furnace platforms where original blower motors are no longer operational.
