OEM Carrier Furnace Control Circuit Board for PG8JAA036070AGJA

The integrated furnace control board is the brain of your Carrier PG8JAA036070AGJA packaged unit. It sequences every heating cycle — energizing the inducer, proving the pressure switch, firing the hot surface igniter, opening the gas valve, and timing the blower on and off delays. It also runs continuous self-diagnostics and flashes fault codes through its onboard LED. When the board fails, symptoms are wide-ranging: the furnace is completely dead with no LED, the blower runs constantly, the unit short-cycles, or it ignites and immediately drops out. This OEM control board carries the relay complement Carrier engineered for this model — typically dedicated relays for the inducer, igniter circuit, gas valve, and both blower heat and cool taps — plus the correct firmware revision and connector pinout. The plug locations, jumper settings, and timing parameters match the PG8JAA wiring harness exactly, so it drops in without rewiring. Control boards are model-specific. A generic or cross-referenced board with mismatched relay ratings or ignition timing can mis-sequence the burners, chatter the gas valve, or fail to prove the pressure switch — risking nuisance lockouts or undersized relay contacts that pit and weld over time. The OEM board's timing and relay sizing are matched to your blower motor and gas valve load. Install difficulty: 3 of 5. Tools: 1/4" nut driver, multimeter, and a phone photo of every connector before you unplug it. #1 safety warning — KILL POWER AT THE BREAKER before servicing; these boards carry line voltage. Transfer wiring one connector at a time to avoid mistakes. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.
