OEM Carrier Integrated Furnace Control Board HK42FZ034 for Model PG8MAA024070AEJA

This OEM Integrated Furnace Control (IFC) board is the factory-specified replacement for the Carrier PG8MAA024070AEJA gas furnace. The control board is the operational brain of your heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower fan while continuously monitoring every safety switch and sensor. When it fails, symptoms range from complete no-heat lockout and repeated ignition failures to erratic blower behavior, fault code flashes, or a furnace that starts but shuts down unexpectedly mid-cycle.

• OEM Part Number: HK42FZ034 | Board References: CEPL131012-01 / CEBD431012-01A | Factory-authorized exact replacement for Carrier PG8MAA024070AEJA
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards carry factory-programmed timing sequences, correct fault code logic, and full UL certification specific to your furnace model. Aftermarket boards often introduce off-spec ignition delays and incorrect safety lockout thresholds that can void your equipment warranty and create unsafe operating conditions.
• Install Difficulty: 3/5 — Disconnect power and gas supply before beginning. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, a smartphone to photograph all wiring connections before removal. Transfer wires one at a time from old board to new. Clear any stored fault codes after installation and run a full heat cycle to verify operation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our climate-controlled warehouse. Free shipping included.
