OEM Carrier Integrated Furnace Control Board HK42FZ034 for Model PG8JAA036070AFJA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG8JAA036070AFJA gas furnace, carrying OEM part number HK42FZ034 (cross-references: CEPL131012-01, CEBD431012-01A). The IFC board is the brain of your furnace — it sequences every stage of the heating cycle, from energizing the inducer motor and monitoring the pressure switch, to firing the igniter, proving the flame via the flame sensor, and distributing blower airflow. When the board fails, symptoms typically include the furnace entering a hard lockout with no heat, erratic or incomplete ignition sequences, a continuously running or non-starting blower fan, or error fault codes flashing on the board's LED indicator.

  • OEM Part Number: HK42FZ034 | Cross-ref: CEPL131012-01 / CEBD431012-01A | Factory-authorized direct replacement — no modifications required
  • OEM vs Generic: This is a genuine Carrier factory board, not an aftermarket substitute. OEM boards preserve factory-calibrated timing sequences for ignition, fan delays, and safety lockouts — critical for reliable and safe furnace operation. Generic boards can introduce mistimed sequences that cause nuisance lockouts or compromise safety shutoffs.
  • Install Difficulty: 3/5 — Requires labeling and disconnecting all harness connectors, removing mounting standoffs, and transferring the board to the existing bracket. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, needle-nose pliers, smartphone camera (photograph all wiring before disconnecting). Turn off power and gas before beginning. Professional installation recommended if unfamiliar with furnace wiring.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Directly replaces the integrated furnace control board in the Carrier PG8JAA036070AFJA gas furnace. Also compatible with select Bryant and Payne models sharing the CEPL131012-01 board specification — verify your existing board's part number against HK42FZ034 before ordering.

My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
