OEM Carrier Integrated Furnace Control Board for PG8MAA066110AGJA

The integrated furnace control board is the brain of your Carrier PG8MAA packaged gas/electric unit. It sequences every ignition cycle—energizing the inducer, proving the pressure switch, firing the hot surface igniter, opening the gas valve, and timing the blower on/off delays—while continuously monitoring flame and safety inputs. When this board fails you'll see the classic symptoms: the furnace won't fire at all, the blower runs constantly or not at all, the unit short-cycles, or the diagnostic LED flashes a hard-lockout fault code. Intermittent no-heat calls in cold weather and a relay that audibly chatters are also tell-tale signs of a failing board. This OEM board carries the correct number of onboard relays for the inducer, blower, and humidifier/EAC terminals, matched ignition-trial timing, and the exact flame-sense threshold Carrier programmed for this furnace. Connector pinouts, line-voltage taps, and the 24V transformer terminals are an exact fit—no jumper rework required. Generic replacement boards frequently use substitute relays with lower contact ratings and altered blower-delay timing, which causes nuisance lockouts, premature relay burnout, and improper temperature rise. An OEM board preserves Carrier's safety logic and flame-proving sequence exactly, protecting the heat exchanger and your warranty. Install difficulty: 3/5. Tools needed: 1/4" nut driver, Phillips screwdriver, multimeter, and a phone to photograph wiring before disconnecting. Safety warning: KILL THE BREAKER and disconnect line power before touching the board—24V and 120V terminals are both live and back-feed from the transformer can shock you even with the thermostat off. 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.
