OEM Carrier Integrated Furnace Control Board HK42FZ013 for Model PG8MAA036045ABJA

This is the OEM factory-specified integrated furnace control (IFC) board for the Carrier PG8MAA036045ABJA gas furnace. The control board is the brain of your heating system — it sequences every stage of the ignition cycle, monitors safety inputs, drives the inducer and blower motors, and commands the gas valve. When it fails, symptoms range from a complete no-heat lockout and repeated ignition attempts to random short-cycling, blower running continuously, or fault codes flashing on the diagnostic LED. Replacing with the correct OEM board restores factory-programmed timing and safety logic that aftermarket boards frequently cannot replicate.

• Specs: Part No. HK42FZ013 | Also cross-references CEPL130438-01 / CEBD430438 | 24 VAC thermostat compatible | Microprocessor-based single-stage HSI control | Diagnostic LED fault codes | Input range: 98–132 VAC at 60 Hz
• OEM vs Generic: OEM boards carry Carrier's exact firmware, terminal layout, and safety-timing parameters. Generic or upgraded aftermarket boards may require wiring harness adapters and can alter ignition trial timing, blower off-delays, and rollout lockout thresholds — introducing liability and callbacks on a warranty job.
• Install difficulty: 3/5 — Disconnect power and label every connector before removal. Tools needed: 1/4" nut driver, needle-nose pliers, phone camera for wiring photos, anti-static wrist strap recommended. Transfer connectors one-for-one; confirm DIP switch or jumper positions match original board before powering up.
• Warranty: OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.
