OEM Carrier Furnace Control Board HK42FZ013 for Model PG9MAB048060ABSA

This is the OEM integrated furnace control (IFC) board for the Carrier PG9MAB048060ABSA gas furnace. The control board is the central brain of your heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower fan in a precise timed cycle. When the board fails, symptoms range from a complete no-heat lockout and continuous LED fault codes to erratic ignition attempts, premature burner shutoff, or a blower that runs non-stop. Replacing with the factory OEM board (part number HK42FZ013) ensures every timing relay, safety interlock, and diagnostic LED operates exactly to Carrier factory specification.

• Specs: OEM Part # HK42FZ013 | Integrated Furnace Control (IFC) | 120V input / 24V control circuit | Compatible with single-stage gas valve and HSI ignition sequence | Onboard diagnostic LED fault code display
• OEM vs Generic: OEM boards carry factory-programmed timing sequences and safety lockout thresholds. Aftermarket boards frequently ship with mis-calibrated ignition trial timers and pressure-switch delay settings that can trigger nuisance lockouts or — worse — unsafe retry behavior.
• Install Difficulty: 3/5 — Requires disconnecting 120V power and 24V low-voltage wiring harnesses. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, phone/camera to photograph all wiring connectors before removal. We strongly recommend labeling each connector. Turn off gas supply and power at the breaker before beginning.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before 3 PM ship same business day from our warehouse.
