The Carrier HK42FZ013 is the factory integrated furnace control (IFC) board for the PG9MAB048100AASA gas furnace. Acting as the brain of the heating system, this microprocessor-based board orchestrates every stage of the heating sequence — from energizing the inducer motor and proving the pressure switch, to firing the hot surface igniter, opening the gas valve, and ramping the blower motor to the correct speed. When this board fails, common symptoms include a furnace that won't ignite, lockout error codes flashing on the diagnostic LED, random short-cycling, or a blower that runs continuously with no heat output.
Compatibility: Direct OEM replacement for Carrier model PG9MAB048100AASA gas furnace. Cross-references CEPL130438-01 and CEBD430438 board assemblies. Verify your existing board's part number on the label before ordering. Not sure it fits?
