OEM Carrier Furnace Control Board HK42FZ013 for Model PG8MAA048110ADJA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG8MAA048110ADJA gas furnace. The control board is the brain of your heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor through every heating cycle. When it fails, symptoms include a furnace that won't light, repeated lockout fault codes, random short-cycling, or a system that's completely unresponsive despite the thermostat calling for heat. Replacing the board with the factory-specified OEM part restores precise sequencing and eliminates nuisance faults caused by out-of-spec aftermarket timing.

  • Specs: Part No. HK42FZ013 | Input: 98–132 VAC at 60 Hz | Igniter Output: 5A at 120 VAC | Cool Blower: 30A, 2 HP, 240 VAC | Heat Blower: 5A, 1/2 HP, 240 VAC | Inducer Motor: 4A at 120 VAC | 24 VAC thermostat compatible | Diagnostic LED fault codes included
  • OEM vs Generic: OEM boards carry factory-calibrated ignition trial timing (5-second trial, 3 retries) and 100% gas shutoff on ignition failure. Generic boards may use looser timing tolerances, increasing the risk of nuisance lockouts or unsafe gas events. For a gas appliance, OEM is strongly recommended.
  • Install Difficulty: 3/5 — Requires shutting off gas and disconnecting 120V power before beginning. Photograph all wiring harness connections before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Electrostatic discharge precautions required — touch a grounded metal surface before handling the board.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Frequently Asked Questions

Does this Control Board fit my Carrier PG8MAA048110ADJA?
Yes. This is the factory-specified OEM control board for the Carrier PG8MAA048110ADJA. 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 PG8MAA048110ADJA?
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?
