OEM Carrier Furnace Control Board HK42FZ013 for Model PG8MAA048070AAJA

This is the OEM integrated furnace control (IFC) board for the Carrier PG8MAA048070AAJA gas furnace, factory part number HK42FZ013 (also cross-referenced as CEPL130438-01 / CEBD430438). The control board is the brain of your furnace — it sequences every heating cycle from thermostat call to burner ignition to blower operation. When it fails, symptoms range from a complete no-heat condition and repeated safety lockouts, to erratic blower behavior, failure to prove flame, or a furnace that starts then immediately shuts down. If you've already ruled out a dirty flame sensor, failed igniter, and pressure switch faults, the control board is the next logical replacement.

• OEM vs Generic: This is the factory-matched OEM board carrying the original Carrier part number HK42FZ013. OEM boards preserve exact timing sequences, safety lockout thresholds, and connector positions — eliminating the adapter harnesses and configuration changes often required by aftermarket replacements.
• Install difficulty: 3/5 — Shut off all power and gas before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone/camera to photograph all wiring before disconnection. ESD precautions required — ground yourself to bare metal on the furnace chassis before handling the board. The board mounts on standoffs inside the blower compartment; swap connectors one at a time to avoid mis-wiring.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
