OEM Carrier Integrated Furnace Control Board HK42FZ018 for Model PG9YAA036060ACSS

This OEM Integrated Furnace Control (IFC) board is the factory-specified replacement for the Carrier PG9YAA036060ACSS gas furnace. The control board is the command center of your heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower in precise timing, while continuously monitoring every safety switch and pressure sensor. When this board fails, the furnace may refuse to fire, lock out after ignition attempts, run the blower continuously, or display a fault code indicating a control failure. Replacing the board with a genuine OEM part restores factory logic and safety thresholds exactly as designed.

• Specs: OEM Part # HK42FZ018 | Cross-references: CEPL130590-01, CEBD430590-10A | Input: 120V | Control circuit: 24V | Weight: ~0.76 lbs | Factory-matched timing and fault-code logic
• OEM vs Generic: This is an authentic Carrier OEM board — not an aftermarket substitute. OEM boards preserve factory ignition timing, blower delay sequences, and error-code diagnostics. Aftermarket boards may use approximated firmware that causes nuisance lockouts or shortens component life.

Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone camera for documentation. Confirm all fault codes are cleared after installation before restoring power.
