OEM Carrier Integrated Furnace Control Board for PG9MAB024060ACSA

The integrated furnace control board is the brain of your Carrier PG9MAB024060ACSA gas package unit. On every thermostat call it sequences the entire ignition cycle — energizing the inducer motor, proving the pressure switch, firing the hot surface igniter, opening the gas valve, and confirming flame through the sensor — while watching the limit and rollout safety circuits. When this board fails you will see classic symptoms: the furnace ignores the thermostat, the blower runs constantly or never starts, the unit short-cycles, or the diagnostic LED flashes a fault code instead of completing a heat cycle. Burnt relays and cracked solder joints around the connectors are common end-of-life failures. This board carries multiple onboard relays governing the inducer, igniter, gas valve, and the multi-speed indoor blower (separate heat and cool taps), plus a 24V control-transformer circuit and onboard diagnostics with a fault-code LED. It is matched to the PG9 platform ignition timing and flame-rectification thresholds, making it a drop-in fit for the ACSA configuration and its wiring harness. A control board switches both gas and high-voltage relays, so component ratings matter. OEM boards use relays rated to the exact inrush of your inducer and blower; generic or rebuilt boards often substitute lower-rated relays and capacitors that pit and weld under repeated switching, causing repeat failures and unsafe gas-valve timing. Factory flame-rectification calibration also ensures the board reliably proves flame instead of nuisance lockouts. Install difficulty: 4 of 5. Tools: 1/4-inch nut driver, multimeter, and a phone photo of the wiring before you begin. #1 safety warning: KILL POWER AT THE BREAKER before touching the board — 120V is present at the relays even with the thermostat off. Label every wire to its terminal. 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.

Compatibility

This part is compatible with Carrier model PG9MAB024060ACSA. Always verify the part number against your unit's data plate before ordering.

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.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
