Westinghouse 903106 Integrated Control Board Condensing Furnace

Product Description

The Westinghouse 903106 is an integrated control board designed for M2RC series condensing furnaces. This board serves as the central logic and sequencing component of the furnace, managing ignition, blower operation, inducer motor control, and safety lockout circuits. It is a direct OEM-style replacement intended for installation by licensed HVAC technicians servicing residential condensing gas furnace systems. The 903106 is compatible with G4, G5, and G6 model variants of the M2RC furnace line, making it a relevant stocking part for technicians who regularly service this equipment.

This control board is used in residential condensing gas furnace applications where the existing integrated board has failed or is presenting fault codes that cannot be cleared through standard diagnostics. Typical install scenarios include board replacement following ignition failures, inducer relay failures, or blower sequencing faults traced to the control board itself. It fits M2RC condensing furnace units across the G4, G5, and G6 model generations as stated by the manufacturer.
