OEM Carrier Furnace Control Board HK42FZ061 for Model PG8JAA066110AGJA

This is the genuine OEM Carrier integrated furnace control (IFC) board, part number HK42FZ061 (board reference CEPL131012-20 / CEBD431012), factory-specified for the Carrier PG8JAA066110AGJA gas furnace. The control board is the brain of your furnace — it sequences every operational stage including inducer pre-purge, hot surface ignition, gas valve activation, blower on-delay, and flame verification. When the board fails, symptoms range from a complete no-heat lockout, erratic short-cycling, or a furnace that ignites momentarily then shuts down, to LED fault codes that won't clear despite all other components testing good. Replacing it with the correct OEM board — not a universal substitute — ensures all timing parameters, fault diagnostics, and safety lockout thresholds remain exactly as Carrier engineered them for your unit.

• Specs: Part # HK42FZ061 | Board Ref: CEPL131012-20 / CEBD431012 | Control voltage: 24V | Compatible ignition type: Hot Surface Ignition (HSI) | Single-stage heating sequence
• OEM vs Generic: OEM boards carry factory-programmed timing and fault logic specific to the PG8JAA066110AGJA. Aftermarket universal boards often lack model-specific lockout thresholds, which can mask safety faults or cause nuisance trips — risking both equipment damage and voided warranties.
• Install difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter, and a phone or camera to photograph all wiring harness connections before removal. Transfer one connector at a time to the new board to avoid mis-wiring. Clear any stored fault codes after installation.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our warehouse — order by 3 PM local time.
