Westinghouse 904532 Air Handler Control Board

Product Description

The WESTINGHOUSE 904532 is a replacement control board designed for multi-poise indoor air handler systems. This board manages the operating logic of the air handler, coordinating blower motor sequencing, communication with the thermostat or system controller, and overall unit function. It is a direct OEM-style replacement intended for installation by licensed HVAC technicians. The 904532 is built to restore proper air handler operation in systems where the original control board has failed or been damaged.

This control board is specified for use in multi-poise indoor air handler configurations, meaning the unit can be installed in multiple orientations to suit the installation layout. It is suited for residential or light-commercial applications where the PAH2VM-series or iQDrive-series air handlers are deployed. Typical installs involve replacement during a no-heat, no-cool, or communication fault diagnosis on the affected air handler.
