OEM Carrier Integrated Furnace Control Board HK42FZ034 for Model PG8JAA036110AEJA

This is the OEM factory-specified Integrated Furnace Control (IFC) board for the Carrier PG8JAA036110AEJA gas furnace, carrying OEM part number HK42FZ034 (board references CEPL131012-01 / CEBD431012-01A). The control board is the brain of your furnace — it sequences every stage of operation including inducer startup, hot surface ignition, gas valve actuation, blower timing, and continuous safety-switch monitoring. When it fails, symptoms range from a furnace that won't light and flashes a fault code, to one that starts but shuts down erratically, runs the blower continuously, or loses all response entirely.

• Specs: OEM Part # HK42FZ034 | Board #s CEPL131012-01 & CEBD431012-01A | 24V control circuit | Single-stage integrated furnace control | Factory-matched connector layout for drop-in replacement
• OEM vs Generic: The OEM board ships with exact-match connectors, pre-set timing delays, and factory-calibrated safety thresholds. Aftermarket alternatives frequently use off-tolerance components that can cause nuisance lockouts, premature failure, or incompatibility with the fault-code diagnostic LED on the PG8JAA036110AEJA.
• Install difficulty: 3/5 — Power down and lock out the furnace at the breaker and gas supply before starting. Photograph all wiring harnesses and terminal positions before disconnecting. Transfer one connector at a time to the new board. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, multimeter. Cycle the furnace through a full heating call after installation and verify no fault codes are displayed.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
