Westinghouse 919943 Integrated Control Board Hsi X-13

Product Description

The WESTINGHOUSE 919943 is an OEM integrated control board designed for furnace applications using hot surface ignition (HSI) systems paired with X-13 blower motor configurations. This board serves as the main logic and control center of the furnace, managing ignition sequencing, blower operation, safety circuit monitoring, and fault diagnostics. It is a direct OEM replacement intended to restore proper system operation when the original control board has failed. Licensed HVAC technicians performing furnace diagnostics and board-level replacements are the primary installers of this component.

This control board is suited for residential furnace installations where HSI ignition and X-13 ECM blower motor control are part of the system design. It is listed for use on Westinghouse furnaces as the main control and logic board. When a furnace exhibits lockout faults, ignition failures, or blower sequencing errors traceable to the control board, this OEM replacement restores factory-specified operation without requiring system modifications.
