OEM Carrier Integrated Furnace Control Board HK42FZ036 for Model PG95SAS48080BAAA

The Carrier HK42FZ036 Integrated Furnace Control Board (IFC) is the factory-authorized OEM brain of your PG95SAS48080BAAA 95% AFUE single-stage gas furnace. The IFC board orchestrates every critical furnace function — inducer startup, igniter timing, gas valve sequencing, flame sensing, blower delays, and fault code diagnostics. When this board fails, symptoms typically include a furnace that won't light, short-cycles after ignition, shows a lockout fault, runs the blower non-stop, or produces no response at all from the thermostat call for heat.

• Part Number & Cross-References: OEM part HK42FZ036 | Also cross-references as CEPL131012-02, CEBD431012-11A, HK42FZ0363416 — all refer to the same factory board revision.
• OEM vs Generic: This is the genuine Carrier Factory Authorized Part, engineered to exact electrical tolerances for the PG95SAS48080BAAA. Aftermarket boards frequently use off-spec relay ratings and timing chips that can cause nuisance lockouts, premature gas valve failures, or voided equipment warranties. OEM is always the right call on a high-efficiency furnace.
• Install Difficulty: 4/5 — Control board replacement requires disconnecting 120V line voltage and multiple low-voltage harnesses. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone/camera to photograph all wiring before disconnection, and a multimeter to verify 24VAC supply and incoming line voltage. If you are not comfortable working around energized equipment, consult a licensed HVAC technician.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed by 3 PM local time ship same business day from our warehouse.
