OEM Carrier Furnace Control Board HK42FZ013 for Model PG8JAA036110ACJA

The Carrier HK42FZ013 integrated furnace control (IFC) board is the command center of your PG8JAA036110ACJA gas furnace. This microprocessor-based board orchestrates every critical function in the heating cycle — sequencing the inducer motor, hot surface igniter, gas valve, and blower motor in precise timed stages. When this board fails, symptoms range from a no-heat lockout condition and repeated ignition attempts to erratic blower behavior, fault codes flashing on the diagnostic LED, or a furnace that simply will not respond to thermostat calls. Replacing it with the correct OEM part restores factory-spec operation immediately.

• Specs: Input range 98–132 VAC at 60 Hz | Ignitor output: 5A at 120 VAC | Cool blower: 30A / 2 HP / 240 VAC | Heat blower: 5A / 1/2 HP / 240 VAC | Inducer motor: 4A FLA / 8.0A LRA at 120 VAC | 24 VAC thermostat compatible | Diagnostic LED fault-code display | Also cross-references CEPL130438-01 / CEBD430438
• OEM vs Generic: This is a genuine OEM Carrier control board factory-matched to your PG8JAA036110ACJA furnace. OEM boards use original firmware and exact connector pinouts, eliminating the wiring harness adapters and configuration changes often required by aftermarket replacements — reducing installation risk and callback potential.
• Install difficulty: 3/5 — Turn off power at the breaker and gas supply before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph existing wiring, and a multimeter. Label all wire connections before removal. Note: this board supersedes to HK42FZ034 in current OEM supply — confirm board revision on your unit's data plate.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
