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.
