OEM Carrier Integrated Furnace Control Board HK42FZ040 for Model PG95XAT60100CBAA

This OEM Integrated Furnace Control (IFC) board is the factory-specified replacement for the Carrier PG95XAT60100CBAA 95% AFUE two-stage gas furnace. As the operational brain of your unit, the control board continuously monitors every safety switch, pressure switch, and sensor — then sequences and coordinates ignition, gas valve operation, inducer, and blower motor functions. When the board fails, symptoms range from a complete no-heat lockout and repeated ignition retries to erratic blower behavior, false fault codes, and furnaces that start but immediately shut down.

  • Specs: Single-stage 120V Hot Surface Ignition (HSI) control | Compatible with PSC blower motors | Board dimensions: 7-1/16" × 6-1/2" | 3-amp on-board fuse | CEPL130948-02 / CEBD430948-08A cross-reference | Made in Mexico
  • OEM vs Generic: This is a genuine Carrier factory-authorized part — not an aftermarket substitute. OEM boards carry factory-programmed timing, retry logic, and fault-code sequences precisely matched to your PG95XAT60100CBAA furnace. Aftermarket boards may introduce timing drift or incompatible lockout behavior that voids manufacturer warranties.
  • Install difficulty: 3/5 — Shut off power and gas at the unit before beginning. Tools needed: ¼" hex driver or Phillips screwdriver, needle-nose pliers, smartphone or camera (photograph all wiring before disconnecting). Transfer wiring harnesses one connector at a time to avoid miswiring. Restore power and run a full ignition test cycle when complete.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our stocked warehouse.

Compatibility: Factory-matched for Carrier model PG95XAT60100CBAA. Also replaces legacy part number HK42FZ028. Verify your existing board's part number against HK42FZ040 before ordering — consult your unit's data plate or wiring diagram inside the furnace cabinet. Have questions? Our HVAC-certified team confirms fitment before you buy. Order now — in stock and ships today.

Difficulty: Advanced (1–2 hrs)

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.
