OEM Carrier Furnace Control Board HK42FZ013 for Model PG9MAB048100AASA

The Carrier HK42FZ013 is the factory integrated furnace control (IFC) board for the PG9MAB048100AASA gas furnace. Acting as the brain of the heating system, this microprocessor-based board orchestrates every stage of the heating sequence — from energizing the inducer motor and proving the pressure switch, to firing the hot surface igniter, opening the gas valve, and ramping the blower motor to the correct speed. When this board fails, common symptoms include a furnace that won't ignite, lockout error codes flashing on the diagnostic LED, random short-cycling, or a blower that runs continuously with no heat output.

  • Specs: 24 VAC control circuit | Input: 98–132 VAC at 60 Hz | Ignitor 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 | OEM part number: HK42FZ013 | Board ref: CEPL130438-01 / CEBD430438
  • OEM vs Generic: This is a genuine OEM Carrier control board built to exact factory specifications. OEM boards carry correct firmware timing, precise ignition trial sequences (5-second trial, 3 retries), and factory-matched connector pinouts — eliminating the wiring adapter kits and reconfiguration steps required with aftermarket replacements.
  • Install difficulty: 3/5 — Shut off gas and disconnect power at the breaker before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera (photograph all wiring before removal). Transfer wiring harness connectors one at a time to avoid miswiring. Consult the unit's wiring diagram on the blower door panel.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PG9MAB048100AASA gas furnace. Cross-references CEPL130438-01 and CEBD430438 board assemblies.

Frequently Asked Questions

Does this Control Board fit my Carrier PG9MAB048100AASA?
Yes. This is the factory-specified OEM control board for the Carrier PG9MAB048100AASA. 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 PG9MAB048100AASA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
