OEM Carrier Control Board for PG8JAA060155AEJA Gas Furnace

The integrated furnace control (IFC) board governs the entire heating sequence on your Carrier PG8JAA060155AEJA package unit. On a call for heat it powers the inducer motor, verifies the pressure switch, energizes the hot-surface igniter, opens the gas valve, reads flame current through the sensor, and then times the blower on and off. It also drives cooling-mode blower operation and reports faults via its diagnostic LED. A failed board shows up as no ignition, a blower stuck on or refusing to start, short-cycling, random no-heat lockouts, or a fault LED that won't reset. Pitted relay contacts and a blown 3A fuse are common failure points. This board uses a microprocessor with several integrated relays for the inducer, igniter, gas valve, and the heat/cool blower speed taps, protected by a 3-amp fuse on the 24V secondary. Blower-off timing is set by onboard jumpers. The AEJA is an earlier A-revision than the AFJA — confirm the exact OEM number printed on your existing board, since timing firmware is not interchangeable across revisions. Why OEM matters: this board's ignition and flame-proving logic are calibrated specifically for this furnace. Generic replacement boards demand rewiring and re-jumpering and frequently use relays rated for fewer switching cycles, which weld shut and cause repeat no-heat failures. The OEM board reconnects to the factory harness and keeps the original safety lockouts intact. Install difficulty: 3/5. Tools: 1/4" nut driver, needle-nose pliers, multimeter, and a camera to document wiring. #1 safety warning: SHUT OFF THE BREAKER before servicing — line-voltage 120V terminals are live on this board.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
