Westinghouse 920994 Variable Speed Furnace Blower Control Board

Product Description

The WESTINGHOUSE 920994 is a variable speed blower control board designed for downflow furnace applications. It manages the operation of the blower motor, coordinating airflow through heating and cooling cycles to maintain system efficiency and comfort. Licensed HVAC technicians install this board as a direct replacement when the original control fails, restoring proper motor speed staging and blower sequencing. The 920994 is engineered for variable speed motor control, making it suited for systems where precise airflow management is required across multiple stages of operation.

This blower control board is intended for use in downflow configuration furnaces, where the airflow travels downward through the heat exchanger and out through the bottom of the unit. It is typically found in residential forced-air heating systems. HVAC professionals replacing a failed or damaged blower control board will find this part appropriate for restoring factory motor control behavior in compatible downflow furnace installations.

Key Features

• Variable speed blower motor control for multi-stage airflow management
• Designed specifically for downflow furnace configurations
• OEM-style replacement for restoring original blower sequencing behavior
• Direct board swap format reduces installation time during service calls

Compatibility

Designed as an OEM-style replacement blower control board for variable speed downflow gas furnace systems.

Installation Notes

Installation of this blower control board should be performed by a licensed HVAC technician. Disconnect all power to the furnace at the disconnect switch and breaker before removing the original board. Follow all applicable local codes and manufacturer wiring diagrams when reconnecting low-voltage and line-voltage connections. Do not power up the unit until all wiring connections are secure and the board is properly mounted in the control compartment.
