OEM Carrier Integrated Furnace Control Board HK42FZ036 for Model PG95SAS30040AAAA

This is the OEM factory-specified Integrated Furnace Control Board (IFC) for the Carrier PG95SAS30040AAAA gas furnace. The control board is the operational brain of your furnace — it sequences every stage of the heating cycle, including inducer start, igniter warm-up, gas valve activation, and blower operation. It continuously monitors pressure switches, limit switches, and flame sensors to protect the system. When the board fails, symptoms typically include a complete no-heat lockout, erratic short-cycling, an inducer that runs but never advances to ignition, or LED fault codes that persist even after resetting the system.

• Part Numbers: HK42FZ036 | Cross-reference: CEPL131012-02, CEBD431012-11A, HK42FZ0363416, CEPL131012-02-I — all factory-equivalent designations for this board
• OEM vs Generic: This is a genuine Carrier Factory Authorized Parts replacement — not an aftermarket substitute. OEM boards ship with original connectors, pre-configured timing sequences, and full diagnostic LED logic matched to your furnace's exact firmware. Generic boards risk mis-matched fault thresholds and voided equipment warranties.
• Install Difficulty: 3/5 — Requires shutting off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring harness connections prior to removal. Transfer wires one-at-a-time to avoid miswiring. Re-run a full heating cycle after install to verify LED status codes.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our warehouse when ordered before 3 PM local time.
