OEM Carrier Integrated Furnace Control Board for PG9MAA024040AFKA

The integrated furnace control board is the command center of your Carrier PG9MAA furnace. On each call for heat it starts the inducer, proves the pressure switch, fires the hot surface igniter, opens the gas valve, monitors flame, and times the blower on/off delays. A failed board shows up as a furnace that won't start, no ignition, constant or absent blower operation, short-cycling, or a flashing diagnostic LED throwing fault codes. Voltage surges and cracked relay solder joints frequently take these boards out. Specs: This microprocessor-controlled board integrates multiple relays — inducer, igniter, gas valve, and heat/cool blower-speed relays — a 24V transformer circuit, and flame-sense circuitry that reads microamp signals from the flame rod. It is engineered to match the PG9MAA control sequence, harness connectors, and LED diagnostics for a direct replacement. Why OEM: Genuine OEM boards carry the exact ignition timing and blower profiles your furnace was designed around. Generic or rebuilt boards often have undersized relay contacts that pit and weld under repeated cycling, or altered timing that causes nuisance lockouts and premature blower starts that push cold air through the ducts. Installing the wrong board invites intermittent faults and shortens the life of the furnace. Install difficulty: 3/5. Tools: 1/4" nut driver, Phillips screwdriver, multimeter, and a phone camera to photograph the wiring before removal. #1 safety warning: kill the breaker AND the furnace disconnect switch before touching the board — line-voltage 120V is present. Tag every wire as you disconnect it. Ships same business day from our stocked warehouse on orders placed before 3 PM CST.

Why Choose OEM?
