OEM Carrier Furnace Control Circuit Board for PG8DAA048115ABJA

The integrated furnace control board is the brain of your Carrier PG8DAA048115ABJA. It sequences the entire heating cycle — energizing the inducer, proving the pressure switch, firing the igniter, opening the gas valve, monitoring the flame sensor, and timing the blower on and off. When the board fails, symptoms are wide-ranging: the furnace may be completely dead with no response to the thermostat, may run the blower constantly, may ignite but never start the main blower, or may flash a diagnostic LED fault code on the board itself. Burned relay contacts, swollen capacitors, or scorched spots near the gas-valve terminals are visible signs of a failed board. This is the genuine OEM control board with the correct relay complement (inducer, gas valve, and line-voltage blower relays) and jumper configuration matched to the PG8DAA furnace family. The board's blower-timing taps and flame-sensing threshold are tuned to this cabinet, which is what makes it a true drop-in replacement. Why OEM matters: a generic or 'universal' board may lack the exact relay ratings or timing logic this furnace expects, leading to nuisance lockouts, incorrect blower delays, or relays that pit and weld under your blower's inrush current. OEM relay ratings and onboard diagnostics keep fault codes accurate and the sequence reliable. Install difficulty: 3 of 5 — the wiring is plug-and-play, but there are many connectors to transfer correctly. Tools: a 1/4" nut driver, a phone to photograph the existing wiring before you start, and a multimeter. SAFETY: kill power at the breaker before touching the board — these terminals carry 120V — and move each wire one at a time to the new board to avoid mis-pinning a connector.
