OEM Carrier Furnace Integrated Control Board HK42FZ013 for Model PG8JAA024070ADJA

This is the factory OEM integrated furnace control (IFC) board for the Carrier PG8JAA024070ADJA gas furnace. The control board is the operational brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor on every heating call. When this board fails, you'll typically see symptoms such as a complete no-heat condition, repeated ignition lockouts, fault codes flashing on the diagnostic LED, or erratic blower behavior. Replacing it with the correct OEM part restores factory-programmed timing, safety shutoffs, and motor outputs exactly as Carrier engineered them.

• Specs: Part No. HK42FZ013 | Input: 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 at 120 VAC | Control Voltage: 24 VAC
• OEM vs Generic: This is the genuine Carrier OEM board — factory-programmed with exact ignition trial timing (5-second trial, 3 retries), certified 100% gas shutoff on ignition failure, and proper brownout/reverse-polarity protection. Aftermarket boards often use generic firmware that can trigger nuisance lockouts or void equipment warranties.
• Install Difficulty: 3/5 — Requires disconnecting 120V line voltage. Always shut off gas supply and power at the breaker before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a phone or camera to photograph all wiring harness connections before removal. Follow Carrier's wiring diagram on the furnace door label.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
