OEM Carrier Furnace Control Board HK42FZ013 for Model PG9MAB048100LBSA

This is the factory OEM integrated furnace control (IFC) board for the Carrier PG9MAB048100LBSA gas furnace. The control board is the central nervous system of your furnace — it sequences every stage of operation, including inducer startup, hot surface ignition, gas valve activation, blower motor timing, and fault code diagnostics. When this board fails, you may experience a hard lockout with no heat, erratic ignition attempts, a continuously running blower, or status LED fault codes indicating a board-level failure. Replacing it with the correct OEM part ensures full compatibility with all connected components and restores factory-programmed timing sequences.

  • Specs: OEM Part Number HK42FZ013 | Factory-matched IFC board | 120V input | 24V control circuit output | Compatible with single-stage gas valve and HSI ignition system
  • OEM vs Generic: This is a genuine Carrier OEM board with factory firmware and exact terminal layout. Aftermarket boards may require wiring modifications, carry mismatched timing sequences, and void equipment warranties — always use OEM on control boards.
  • Install Difficulty: 3/5 — Moderate skill required. Power off and lock out the furnace at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections prior to removal. Transfer one connector at a time to avoid miswiring. Verify all LED indicators on the new board before closing the cabinet.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PG9MAB048100LBSA gas furnace. Always cross-reference the part number printed on your existing board before ordering, as similar Carrier models may use a different board revision. Need help confirming fitment?

Frequently Asked Questions

Does this Control Board fit my Carrier PG9MAB048100LBSA?
Yes. This is the factory-specified OEM control board for the Carrier PG9MAB048100LBSA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier PG9MAB048100LBSA?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
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?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
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.
How fast does National HVAC Parts ship?
